In hydrology, there are two similar but distinct definitions in use for the word drawdown: • In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. • In surface water hydrology and civil engineering, drawdown refers to the lowering of the surface elevation of a body of water, the water table, the piezometric surface, or the water surface of a well, as a result of th… WebFeb 2, 2024 · An analytical solution is presented for groundwater flow to a well in an aquifer with double-porosity behavior and transient transfer between fractures and matrix. The solution is valid for fractional flow dimensions including linear, cylindrical or spherical flow to the well and for fractional inter-porosity diffusive transfer including release from storage …

WebMar 21, 2013 · Two step test drawdown curves are shown in Figure 1. One is a curve for a hypothetical pumping well with no "well loss," and the other curve is for the same well with severe well loss. (Well loss is drawdown caused by restrictions to groundwater flow interfering with the movement of water into the well.)
