Transient motion of groundwater (subsurface water) in the presence of evaporation
Abstract
The spread of a mound of groundwater in the region between two parallel channels with different water levels (H_{1} at x = 0 and H_{2} at x = L) during irrigation is studied with due allowance for evaporation. Evaporation is taken into account in relation to the depth of the groundwater h(x, t); its intensity is regarded as zero when h < h_{0} (where h_{0} is the critical level of the groundwater), while varying linearly or remaining constant when h > h_{0}. The intensity or irrigation is regarded as constant. This problem is solved by using the thermal potentials of a double layer and reduces to the solution of a nonlinear integral equation.
