Estimating groundwater flow
WebMar 10, 2011 · 1. Introduction [2] Groundwater flow velocities, i.e., migration rates along the hydraulic gradient from high to low hydraulic head, can generally be obtained by application of Darcy's law. This conventional approach implies that the slope of the piezometric surface between two groundwater monitoring wells can be assumed constant. WebGroundwater 32:949–957 Moench, A. 1995.
