Identification of Aquifer and Pumped Well Parameters Using the Data Hidden in Non-Linear Losses

During the pumping of wells, groundwater level drawdown, as measured in pumped well, is increased by non-linear losses caused water flow velocity through well screens. This undermines adequacy direct use drawdown data for purpose realistic identification effective radius and aquifer parameters. anomaly avoided reshaping function into a specific sw/Q well. simplifies exclusion from sequence at position Combining linear respective rate radial was formed. describes parameter relations during test pumping. A consistent reveals actual value coefficient nonlinear losses. Moreover, enables reliable estimation transmissivity using only data.
