Thiem's equation
WebThe well formula according to Dupuit-Thiem is an equation in hydrogeology, the sub-area of geology that deals with groundwater and related topics. The well formula relates the withdrawal of water by a well with the permeability of the aquifer and the groundwater level. The well formula is formulated in two different cases: once for confined and once for … Web30 Jun 2024 · We explain the origin of the Thiem equation and illus... This video is about the Thiem equation which describes steady state flow to wells in confined aquifers.

WebEquations [3-8a] to [3-8c] are different applications of the Thiem equation, which estimates drawdown in an aquifer or well under steady-state conditions. As previously mentioned, it is assumed that the changes in saturated aquifer thickness are small compared with the total saturated depth. This is necessarily true in a confined aquifer, but ...
