Calculate the groundwater flow per unit width of a confined aquifer which can be divided into three homogeneous areas with different hydraulic conductivities. Also determine the position of the piezometric surface on the cross-section and the "equivalent hydraulic conductivity". Solve the following problem analytically and using IGW-NET and compare the results.

Consider the head distribution along the length of an confined aquifer that is adjacent to two constant head boundaries and receiving constant recharge to the top of the aquifer. Develop a IGW-NET model to reproduce the above analytical solution.

(Intermediate - Analytical and numerical sub-problems.) The irrigation system for the Spartan valley is to control the water table at a minimum of 3.5 ft below the ground surface. This is done to prevent flooding in agricultural fields which can damage or completely destroy crops. The proposed solution is to create a system of 6ft. deep parallel ditches that `remove' groundwater through surface seepage, such that the water table does not rise to a depth less than the minimum allowable depth.

Consider the head distribution along the length of an unconfined aquifer that is adjacent to two constant head boundaries and receiving constant recharge to the top of the aquifer. Develop a IGW-NET model to reproduce the above analytical solution. Further develop the model to simulate vertical flow that is important in the area near the groundwater divide.

A water supply well at a paper factory is tapping an unconfined aquifer which is exposed to significant infiltration from precipitation. An incomplete record shows a fairly constant drawdown in the well and the two nearby abandoned wells. From the available data find the average pumping rate of the well and the average annual infiltration rate. Solve the following problem analytically and using IGW-NET and compare the results.

There was an incident with a cargo train that resulted in a major accidental spill of harmful chemicals. The contaminated groundwater is migrating toward a river used for drinking water supply for a large population center. ​Construction of a drainage gallery and an infiltration channel for aquifer flushing is proposed for the cleanup of the contaminant plume. Develop a IGW-NET model of the groundwater inflow into the drainage gallery for the given parameters/conditions. Also solve the problem analytically and compare the results.

Intermediate - Analytical approach (numerical sub-problem under development). Background: One of the primary delivery mechanisms of chemicals into lakes is the discharge of groundwater through lakebed sediments. The transfer of chemicals and nutrients such nitrogen and phosphorus, carbon, etc. affects the biological processes in the lake and helps to control the biochemical characteristics of the lakes and co-dependent ecosystems (including those downstream of the lake).

Beginner to Intermediate -- Analytical and numerical components. Background: A sandstone aquifer connects a reservoir with a river in a canyon as shown below. Impermeable shale lies above and below the aquifer, and along the river and reservoir where the aquifer is not connected. A portion of the aquifer near the river is unconfined.

Alluvial fans are fan-shaped deposits of water-transported material (alluvium) that typically form at the base of topographic features where there is a marked break in slope. Develop the solution for the water table elevation h(r), verify your analytical solution with IGW-NET using a set of assumed typical parameters.

Artificial Storage and Recovery (ASR) facilities inject treated wastewater or surface water into an aquifer. Some ASR facilities inject groundwater from a different aquifer. Watch the related videos, answer short questins, and reproduce the animations/models using IGW-NET

Seawater intrusion in coastal aquifers is a widespread and serious problem in many parts of the world. Groundwater degradation due to seawater intrusion is often accentuated in small island aquifers due to overpumping or limited replenishing amounts of precipitation. Solve an example problem analytically and numerically using IGW-NET.
