A detailed finite-difference approach is presented for the simulation of transient radial flow in multi-layer systems. The proposed discretization scheme simulates drawdown within the well more accurately than commonly applied schemes. The solution is compared to existing (semi) analytical models for the simulation of slug tests and pumping tests with constant discharge in singleand multi-layer...

The Massachusetts Military Reservation is located in the western portion of Cape Cod. World War II and the period immediately afterward saw the most intense military activity on the base. During this time, chemicals leached into the groundwater and contaminated the aquifer. One of the larger regions, or plumes, of groundwater contamination is the Chemical Spill 10 (CS10) plume, a region in whic...

In Ethiopia, groundwater is the main source of freshwater to support human consumption and socio-economic development. Little Akaki watershed located in Upper Awash basin, known for its high annual rainfall considered as potential recharge zone. On contrary, urbanization industrial expansion are increasing at an alarming rate area. This became a concern threatening resources’ sustainability. To...
