Click here: http://cook.ba/2qouQFb This video is sponsored by Blue Apron. Most of us think about erosion on the surface of the earth, but erosion can occur in the subsurface as well. In fact, scientist and engineers have a very creative name for just such a process: internal erosion. If just the right factors come together in the subsurface, some very interesting things can occur, including sinkholes. -Patreon: http://patreon.com/PracticalEngineering -Website: http://practical.engineering Memories by SNDR & Joey Shigrov is licensed under a Creative Commons Attribution License Source: https://www.youtube.com/watch?v=S1Q2PpM5To8 Tonic and Energy by Elexive is licensed under a Creative Commons Attribution License Source: https://www.youtube.com/watch?v=U6fBPdu8w9U

Great Animation Shows How Deep Humans Dug Into The Earth
 
02:54
Courtesy of Tech Insider --- Extreme Journey to the center of the Earth - Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments, crust, and upper mantle. In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere, mostly microbial life, preserved in drilled samples. Most of the technology used for drilling come from advances in the oil and gas industry. Scientific drilling is carried out on land by the International Continental Scientific Drilling Program (ICDP) and at sea by the Integrated Ocean Drilling Program (IODP). Scientific drilling on the continents includes drilling down into solid ground as well as drilling from small boats on lakes. Sampling thick glaciers and ice sheets to obtain ice cores is related but will not be described further here. Like probes sent into outer space, scientific drilling is a technology used to obtain samples from places that people cannot reach. Human beings have descended as deep as 2,080 m (6,822 ft) in Voronya Cave, the world's deepest known cave, located in the Caucasus mountains of the country of Georgia. Gold miners in South Africa regularly go deeper than 3,400 m, but no human has ever descended to greater depths than this below the Earth's solid surface. As depth increases into the Earth, temperature and pressure rise. Temperatures in the crust increase about 15°C per kilometer, making it impossible for humans to exist at depths greater than several kilometers, even if it was somehow possible to keep shafts open in spite of the tremendous pressure. Scientific drilling is interdisciplinary and international in scope. Individual scientists cannot generally undertake scientific drilling projects alone. Teamwork between scientists, engineers, and administrators is often required for success in planning and in carrying out a drilling project, analyzing the samples, and interpreting and publishing the results in scientific journals. Humans have reached the moon and are planning to return samples from Mars, but when it comes to exploring the land deep beneath our feet, we have only scratched the surface of our planet. This may be about to change with a $1 billion mission to drill 6 km (3.7 miles) beneath the seafloor to reach the Earth's mantle -- a 3000 km-thick layer of slowly deforming rock between the crust and the core which makes up the majority of our planet -- and bring back the first ever fresh samples. It could help answer some of our biggest questions about the origins and evolution of Earth itself, with almost all of the sea floor and continents that make up the Earth´s surface originating from the mantle. Geologists involved in the project are already comparing it to the Apollo Moon missions in terms of the value of the samples it could yield. However, in order to reach those samples, the team of international scientists must first find a way to grind their way through ultra-hard rocks with 10 km-long (6.2 miles) drill pipes -- a technical challenge that one of the project co-leaders Damon Teagle, from the UK's University of Southampton calls, "the most challenging endeavor in the history of Earth science." 'A ship flying in space:' Earth seen through the eyes of an astronaut Their task will be all the more difficult for being conducted out in the middle of the ocean. It is here that the Earth´s crust is at its thinnest at around 6 km compared to as much as 60 km (37.3 miles) on land. Drilling all the way to the mantle would also give geologists a look at what they call the Mohorovičić discontinuity, or Moho, for short. Above this mysterious zone, named for the Croatian seismologist who discovered it in 1909, seismic waves travel at around 4.3 miles per second, a rate consistent with those waves traveling through basalt, or cooled lava. Below the Moho, the waves rip along at around 5 miles per second, similar to the rate they travel through a silica-poor type of igneous rock called peridotite. The Moho typically lies between 3 to 6 miles below the ocean floor and anywhere between 12 to 56 miles beneath the continents. This zone has long been considered the crust-mantle boundary, where material gradually cools and sticks to the overlying crust. But some lab studies suggest it’s possible that the Moho represents the zone where water seeping down from the overlying crust reacts with mantle peridotites to create a type of mineral called serpentine. This possibility is exciting, Dick and MacLeod suggest. The geochemical reactions that generate serpentine also produce hydrogen, which can then react with seawater to produce methane, a source of energy for some types of bacteria. Or, the researchers note, the Moho could be something else entirely unknown to science.

What is GOLD PROSPECTING? What does GOLD PROSPECTING mean? GOLD PROSPECTING meaning & explanation
 
03:43
What is GOLD PROSPECTING? What does GOLD PROSPECTING mean? GOLD PROSPECTING meaning - GOLD PROSPECTING definition - GOLD PROSPECTING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Gold prospecting is the act of searching for new gold deposits. Methods used vary with the type of deposit sought and the resources of the prospector. Although traditionally a commercial activity, in some developed countries placer gold prospecting has also become a popular outdoor recreation. Prospecting for placer gold is normally done with a gold pan or similar instrument to wash free gold particles from loose surface sediment. The use of gold pans is centuries old, but is still common among prospectors and miners with little financial backing. Deeper placer deposits may be sampled by trenching or drilling. Geophysical methods such as seismic, gravity or magnetics may be used to locate buried river channels that are likely locations for placer gold. Sampling and assaying a placer gold deposit to determine its economic viability is subject to many pitfalls. Once placer gold is discovered, the gold pan is usually replaced by sluices or mechanical devices to wash greater volumes of material. Discovery of placer gold has often resulted in discovery of hardrock gold deposits when the placers are traced to their sources. Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Drilling is often used to explore the subsurface. Surface geophysical methods may be used to locate geophysical anomalies associated with gold deposits. Samples of rocks or soil may be collected for geochemical laboratory assay, to determine metal content or detect geochemical anomalies. Hardrock gold particles may be too small to see, even with a microscope. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in developing countries. A recent study by Australian scientists found that termites have been found to excrete trace deposits of gold. According to the CSIRO, the termites burrow beneath eroded subterranean material which typically masks human attempts to find gold, and ingest and bring the new deposits to the surface. They believe that studying termite nests may lead to less invasive methods of finding gold deposits. Small-scale recreational prospecting for placer gold has been seen in many parts of the world including New Zealand (especially in Otago), Australia, South Africa, Wales (at Dolaucothi and in Gwynedd), in Canada and in the United States especially in western states but also elsewhere.

Find more effects of mining right here: http://www.buzzle.com/articles/how-does-mining-affect-the-environment.html Mining is the source of all the substances that cannot be obtained by industrial processes or through agriculture. Mining reaps huge profits for the companies that own them and provides employment to a large number of people. It is also a huge source of revenue for the government. Despite its economic importance, the effects of mining on the environment is a pressing issue. Mining activities require the clearing of large areas of land. The chemicals used in the mining process often escape into the environment causing pollution. Watch this video to know how mining affects the environment.

Explore the Critical Zone
 
06:27
The Critical Zone supports terrestrial life on Earth. It is the region above and below the Earth surface, extending from the tops of the trees down through the subsurface to the bottom of the groundwater. Critical Zone scientists work to discover how this living skin is structured, evolves, and provides essential functions that sustain life. The national Critical Zone Observatory Network is made up of nine environmental observatories each located in a different climatic and geologic setting. CZO scientists observe and measure a set of common parameters at each site. Building a common set of measurements across a diverse range of environmental conditions allows scientists to examine the underlying factors responsible for ecosystem growth and resilience. Through interdisciplinary investigation, CZ scientists help us understand the essential functions that sustain life on Earth. This project is in partnership with the Paleontological Research Institution.

Oil Drilling | Oil & Gas Animations
 
08:22
- Like our Facebook: https://www.facebook.com/oilvips - Geologists and geophysicists have agreed on the existence of a "prospect", a potential field. In order to find out if hydrocarbons are indeed trapped in the reservoir rock, we must drill to hit them. Bearing in mind the knowledge acquired about the substratum and the topography of the land, the best position for the installation of the drilling equipment is determined. Generally it is vertically above the point of maximum thickness of the geological layer suspected of containing hydrocarbons. The drillers then make a hole in conditions that are sometimes difficult. Of small diameter (from 20 to 50 cm) this hole will generally go down to a depth of between 2000 and 4000 meters. Exceptionally, certain wells exceed 6000 m. One of them has even exceeded 11 000 m! Certain fields can be buried at a depth equivalent to the height of 12 Eiffel Towers ... The derrick is the visible part of the drilling rig. It is a metal tower several tens of meters high. It is used to vertically introduce the drill strings down the hole. These drill strings are made up of metallic tubes screwed end to end. They transmit a rotating movement (rotary drilling) to the drilling tool (the drill bit) and help circulate a liquid called "mud" (because of its appearance) down to the bottom of the well. The drilling rig works like an enormous electric hand-drill of which the derrick would be the body, the drill strings the drive and the drilling tool the drill bit. The most usual tool is an assembly of three cones -- from which comes the name "tri cone" -- in very hard steel, which crushes the rock. Sometimes when the rock being drilled is very resistant, a single- block tool encrusted with diamonds is used. This wears down the rock by abrasion. Through the drill pipes, at the extremity of which the drill bit rotates, a special mud is injected, which the mud engineer prepares and controls. This mud cools the drill bit and consolidates the sides of the borehole. Moreover it avoids a gushing of oil, gas or water from the layer being drilled, by equilibrating the pressure. Finally, the mud cleans the bottom of the well. As it makes its way along the pipes, it carries the rock fragments (cuttings) to the surface. The geologist examines these cuttings to discover the characteristics of the rocks being drilled and to detect eventual shows of hydrocarbons. The cuttings, fragments of rock crushed by the drill bit, are brought back up to the surface by the mud. To obtain information on the characteristics of the rock being drilled, a core sample is taken. The drill bit is replaced by a hollow tool called a core sampler, which extracts a cylindrical sample of several meters of rock. This core supplies data on the nature of the rock, the inclination of the layers, the structure, permeability, porosity, fluid content and the fossils present. After having drilled a few hundred of meters, the explorers and drillers undertake measurements down the hole called loggings, by lowering electronic tools into the well to measure the physical parameters of the rock being drilled. These measures validate, or invalidate, or make more precise the hypotheses put forward earlier about the rocks and the fluids that they contain. The log engineer is responsible for the analysis of the results of the various loggings. The sides of the well are then reinforced by steel tubes screwed end to end. These tubes (called casings) are cemented into the ground. They isolate the various layers encountered. When hydrocarbons are found, and if the pressure is sufficient to allow them come to the surface naturally, the drillers do a flow check. The oil is allowed to come to the surface during several hours or several days through a calibrated hole. The quantity recovered is measured, as are the changes in pressure at the bottom of the well. In this way, a little more knowledge is gained about the probable productivity of the field. If the field seems promising, the exploration team ends the first discovery well and goes on to drill a second, even several others, several hundred or thousand meters further away. In this way, the exploration team is able to refine its knowledge about the characteristics of the field. The decision to stop drilling is made only when all these appraisal wells have provided sufficient information either to give up the exploration or to envisage future production. --------------------------------------------------------------------------------------- Like our Facebook: https://www.facebook.com/oilvips Twitter: https://twitter.com/oilvips And Don't forget to subscribe to our channel

Executive VP of Columbus Gold Peter Kendrick explains what Geophysics is, and how it can be used to help identify mineral deposits. From Wikipedia: Exploration geophysics is the applied branch of geophysics which uses surface methods to measure the physical properties of the subsurface Earth, in order to detect or infer the presence and position of ore minerals, hydrocarbons, geothermal reservoirs, groundwater reservoirs, and other geological structures. Exploration geophysics is the practical application of physical methods (such as seismic, gravitational, magnetic, electrical and electromagnetic) to measure the physical properties of rocks, and in particular, to detect the measurable physical differences between rocks that contain ore deposits or hydrocarbons and those without.

USGS Scenario Evaluator for Electrical Resistivity Survey Design Tool

This video provides an overvew of the USGS Scenario Evaluator for Electrical Resistivity (SEER). Today’s environmental site managers have many tools to choose from when conducting site characterization and remediation. Geophysical tools can provide noninvasive ways to see inside the earth, much like how medical imaging lets us see inside the human body. The USGS Scenario Evaluator for Electrical Resistivity (or "SEER") is a quick and simple tool practitioners can use to assess the likely outcome of using two-dimensional electrical resistivity imaging for site characterization and remediation monitoring. Electrical resistivity imaging is a widely used geophysical method for environmental site management studies. The method is sensitive to fluid conductivity, interconnected porosity, saturation, clay content, and metallic materials.

Evolution of Risk Management...in Underground Engineering - 2006 Buchanan Lecture by C.Baker
 
01:53:11
The Spencer J. Buchanan Lecture Series on the GeoChannel is presented by the Geo-Institute of ASCE. For more information about the Geo-Institute: http://www.asce.org/geotechnical-engineering/geo-institute/ The 14th Spencer J. Buchanan Lecture in the Department of Civil Engineering at Texas A&M University was given by Clyde N. Baker, Jr., PE, SE on Nov. 17, 2006. "Evolution of Risk Management as a Project Management Tool in Underground Engineering" Abstract: Cost effective foundation design may entail use of mixed foundation systems which can require more accurate and reliable load deformation prediction capability. In the writer's experience, the Menard in-situ pressuremeter test has been very useful in enabling better load deformation prediction with different foundation support systems. Case histories are presented to illustrate five different design concepts: 1) Complex existing foundation conditions required dewatering effots to permit belled caisson construction below the old caissons. 2) Use of piles or drilled shafts as settlement reducers rather than as required structural elements for building support. 3) Use of deeper basement excavation stress release effects in ways to maximize site building capacity. 4) Use of variable length piles under a mat to minimize differential settlement. 5) Re-use of existing deep foundations on one bearing stratum in combination with new foundations on deeper stratum. About Clyde N. Baker, Jr.: Mr. Baker received his BS and MS degrees in Civil Engineering from the Massachusetts Institute of Technology and joined the staff of STS Consultants, Ltd. (formerly Soil Testing Services) in the fall of 1954. Over the past 50 years, he has served as geotechnical engineer for many high rise built in Chicago. He has also served as geotechnical engineer or consultant on seven of the sixteen tallest buildings in the world including the three tallest in Chicago (Sear s, Hancock, and Amoco) and the current two buildings in the world, the Petronas Towers in Kuala Lumpur, Malaysia and 101 Financial Center inTaipei, Taiwan. As a result of his experience, Mr. Baker has developed an international reputation in the design and construction of deep foundations. He has been a leader in using in-situ testing techniques correlated with past building performance to develop more efficient foundation designs. In the Chicago soil profile this has facilitated economical use of belled caissons on hard pan for major structures in the 60 to 70 story height range (such as Water Tower Place, 900 North Michigan, and AT&T) which normally would have required extending caissons to rock at significant cost premium. Mr. Baker has shared his knowledge and experience with his peers through numerous Conference and University lectures, technical articles, papers and publications. He is the recipient of the Deep Foundation’s Institute Distinguished Service Award, the ADSC Outstanding Service Award, ASCE’s Thomas A. Middlebrooks and Martin S. Kapp awards and of three Meritorious Publication Awards from SEAOI including the "History of Chicago Building Foundations 1948 to 1998". He is the author of "The Drilled Shaft Inspectors' Manual" sponsored jointly by the Deep Foundation Institute and the International Association of Foundation Drilling (ADSC).

KEENE DRYWASHER Gold in Wickenburge Arizona . GOLD RUNNERSS the dirt was wet or els our results would have been amazing Prospecting for placer gold is normally done with a gold pan or similar instrument to wash free gold particles from loose surface sediment.[1] The use of gold pans is centuries old, but is still common among prospectors and miners with little financial backing. Deeper placer deposits may be sampled by trenching or drilling.[2] Geophysical methods such as seismic, gravity or magnetics may be used to locate buried river channels that are likely locations for placer gold.[3] Sampling and assaying a placer gold deposit to determine its economic viability is subject to many pitfalls.[4] Once placer gold is discovered, the gold pan is usually replaced by sluices or mechanical devices to wash greater volumes of material. Discovery of placer gold has often resulted in discovery of hardrock gold deposits when the placers are traced to their source Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Drilling is often used to explore the subsurface. Surface geophysical methods may be used to locate geophysical anomalies associated with gold deposits. Samples of rocks or soil may be collected for geochemical laboratory assay, to determine metal content or detect geochemical anomalies.[5] Hardrock gold particles may be too small to see, even with a microscope. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in third-world countries. A recent study by Australian scientists found that termites have been found to excrete trace deposits of gold. According to the CSIRO, the termites burrow beneath eroded subterranean material which typically masks human attempts to find gold, and ingest and bring the new deposits to the surface.

Thallium is used for various high-technology products (optics, electronics or even medicine).It is only used in small amounts, but because of its unique characteristics it has become an important raw material in modern consumer electronics. Nevertheless, Thallium is toxic. Since Thallium is also a by-product of mining processes and is transferred into natural water and soil supplies, it is important to identify Thallium concentrations in food plants and water respectively.

Subsidence - Video Learning - WizScience.com
 
02:09
"Subsidence" is the motion of a surface as it shifts downward relative to a datum such as sea-level. The opposite of subsidence is uplift, which results in an increase in elevation. Ground subsidence is of concern to geologists, geotechnical engineers and surveyors. Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in the subsurface causes the creation of voids . If the roof of these voids becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface. This type of subsidence can result in sinkholes which can be many hundreds of meters deep. Several types of sub-surface mining, and specifically methods which intentionally cause the extracted void to collapse will result in surface subsidence. Mining-induced subsidence is relatively predictable in its magnitude, manifestation and extent, except where a sudden pillar or near-surface underground tunnel collapse occurs . Mining-induced subsidence is nearly always very localized to the surface above the mined area, plus a margin around the outside. The vertical magnitude of the subsidence itself typically does not cause problems, except in the case of drainage –rather, it is the associated surface compressive and tensile strains, curvature, tilts and horizontal displacement that are the cause of the worst damage to the natural environment, buildings and infrastructure. Where mining activity is planned, mining-induced subsidence can be successfully managed if there is co-operation from all of the stakeholders. This is accomplished through a combination of careful mine planning, the taking of preventive measures, and the carrying out of repairs post-mining.

Ground Penetrating Radar (GPR) B-Scan Collection (FDTD Animation) [Georadar]
 
01:06
Here, B-scan data collection of a simple ground penetrating radar (GPR) is animated through the use of Finite-difference time-domain (FDTD) method. The upper part of the animation shows the 2D spatial propagation of the short pulse transmitted from the antenna at different spatial locations. The transmitting antenna shoots a short electromagnetic pulse (with a central frequency of 600 MHz) into the subsurface where the relative dielectric permittivity is 4. The short pulse is reflected from the air-soil interface and then from the target embedded in the subsurface. Then, the scattered signals are recorded by the same antenna in the receiving mode. The lower part of the animation corresponds to the received signals (A-scan) at the same antenna for each of the positions. This constitutes the so-called B-scan data collection.

GOLD PROSPECTING TIPS  .. GOLD RUNNERSS
 
01:56
gold prospecting in america is bac Prospecting for placer gold is normally done with a gold pan or similar instrument to wash free gold particles from loose surface sediment.[1] The use of gold pans is centuries old, but is still common among prospectors and miners with little financial backing. Deeper placer deposits may be sampled by trenching or drilling.[2] Geophysical methods such as seismic, gravity or magnetics may be used to locate buried river channels that are likely locations for placer gold.[3] Sampling and assaying a placer gold deposit to determine its economic viability is subject to many pitfalls.[4] Once placer gold is discovered, the gold pan is usually replaced by sluices or mechanical devices to wash greater volumes of material. Discovery of placer gold has often resulted in discovery of hardrock gold deposits when the placers are traced to their sources.Prospectors for hardrock, or lode gold deposits, can use many tools. It is done at the simplest level by surface examination of rock outcrops, looking for exposures of mineral veins, hydrothermal alteration, or rock types known to host gold deposits. Field tools may be nothing more than a rock hammer and hand lens. Hardrock gold deposits are more varied in mineralogy and geology than placer deposits, and prospecting methods can be very different for different types of deposits. As with placer gold, the sophistication of methods used to prospect for hardrock gold vary with the financial resources of the prospector. Drilling is often used to explore the subsurface. Surface geophysical methods may be used to locate geophysical anomalies associated with gold deposits. Samples of rocks or soil may be collected for geochemical laboratory assay, to determine metal content or detect geochemical anomalies.[5] Hardrock gold particles may be too small to see, even with a microscope. Most gold today is produced in large open-pit and deep underground mines. However, small-scale gold mining is still common, especially in third-world countries. A recent study by Australian scientists found that termites have been found to excrete trace deposits of gold. According to the CSIRO, the termites burrow beneath eroded subterranean material which typically masks human attempts to find gold, and ingest and bring the new deposits to the surface. They believe that studying termite nests may lead to less invasive methods of finding gold deposits.[6] Gold mining in Alaska Gold in California Gold nugget Gold panning Gold Prospectors Association of America Gold rush Hushing Mineral exploration Placer mining Recreational gold mining

Searching for hidden continents and mountains ... Geoscientists take us for a rail journey from Kraków to Warszawa, crossing “the most important boundary in Europe”. It is invisible and very few know about it … We can identify this invisible boundary thanks to geophysics, the science which holds the key to a hidden and yet fascinating subsurface world. You are welcome to join this trip. Prof. Marek Lewandowski and Dr habil. Piotr Krzywiec from the ING PAN - Institute of Geological Sciences of the Polish Academy of Sciences make the geophysics easy to follow and enjoy.

HGS-WRF California Basin Model
 
00:41
Integrated Hydrosystem Modeling of the California Basin The Western United States is facing one of the worst droughts on record. Climate change projections predict warmer temperatures, higher evapotranspiration rates, and no foreseeable increase in precipitation. California, in particular, has supplemented their decreased surface water supplies by mining deep groundwater. However, this supply of groundwater is limited, especially with reduced recharge. These combined factors place California’s water-demanding society at dire risk. In an effort to quantify California’s risks, we present a fully integrated water cycle model that captures the dynamics of the subsurface, land surface, and atmospheric domains over the entire California basin. Our water cycle model combines HydroGeoSphere (HGS), a 3-D control-volume finite element model that accommodates variably-saturated subsurface and surface water flow with evapotranspiration processes to the Weather Research and Forecasting (WRF) model, a 3-D finite difference nonhydrostatic mesoscale atmospheric simulator. The two-way coupling within our model, referred to as HGS-WRF, tightly integrates the water cycling processes by passing precipitation and potential evapotranspiration data from WRF to HGS, while exchanging actual evapotranspiration and soil saturation data from HGS to WRF. Furthermore, HGS-WRF implements a flexible coupling method that allows each model to use a unique mesh while maintaining mass conservation within and between domains. Our simulation replicated field measured evapotranspiration fluxes and showed a strong correlation between the soil saturation (depth to groundwater table) and latent heat fluxes. Altogether, the HGS-WRF California basin model is currently the most complete water resource simulation framework as it combines groundwater, surface water, the unsaturated zone, and the atmosphere into one coupled system. The simulation below illustrates the coupled model running for a six day time period. The first plot, Log Depth, is the surface water elevations over the entire basin in log base 10 units (so a value of -2 is actually 1 cm). The next plot illustrates Precipitation shown as meters per second. The third plot Evapotranspiration is the amount of water coming out of the surface and subsurface as evaporation and from plants (transpiration). The last plot is the change in soil moisture from the initial condition, these values are negative values because the soil is drying with time. I am presenting this research at the American Geophysical Union Tuesday, 15 December 2015 in San Francisco. Hope to see you there!
