DR. Mahdi S. Hantush (1921–1984) was a prominent Iraqi-born American hydrologist known for his analytical work on leaky aquifers and well hydraulics. He was the founder of the New Mexico Tech Hydrology Program. His granddaughter is Yasmin Younis, the 2018 Student Commencement Speaker at Boston University’s 185th Commencement, which went ...
the aquifer material is incompressible (no change in matrix due to changes in pressure — aka subsidence), the water is of constant density (incompressible), any external loads on the aquifer (e.g., overburden, atmospheric pressure) are constant, for the 1D radial problem the pumping well is fully penetrating a non-leaky aquifer,
In hydrology, a well test is conducted to evaluate the amount of water that can be pumped from a particular water well.More specifically, a well test will allow prediction of the maximum rate at which water can be pumped from a well, and the distance that the water level in the well will fall for a given pumping rate and duration of pumping.
Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries. A slug test is a variation on the typical aquifer test where an instantaneous change (increase or decrease) is made, and the effects are observed in the same well.
Unconfined aquifers are sometimes also called water table or phreatic aquifers, because their upper boundary is the water table or phreatic surface (see Biscayne Aquifer). Typically (but not always) the shallowest aquifer at a given location is unconfined, meaning it does not have a confining layer (an aquitard or aquiclude) between it and the ...
The military next week plans to begin draining fuel from World War II-era underground fuel tanks in Hawaii, nearly two years after the massive facility sickened 6,000 people when it leaked jet ...
An aquifer is called semi-confined when a saturated layer with a relatively small horizontal hydraulic conductivity (the semi-confining layer or aquitard) overlies a layer with a relatively high horizontal hydraulic conductivity so that the flow of groundwater in the first layer is mainly vertical and in the second layer mainly horizontal.
Typical aquifer cross-section. An unambiguous definition of "groundwater model" is difficult to give, but there are many common characteristics. A groundwater model may be a scale model or an electric model of a groundwater situation or aquifer. Groundwater models are used to represent the natural groundwater flow in the environment.
