Abstract: In this paper, we present a stochastic-analytical approach for uncertainty modeling in two-dimensional, statistically nonuniform groundwater flows. In particular, we develop simple closed-form expressions that can be used ...

Abstract: The Richard’s equation was used to numerically model 1D flow within unsaturated topsoil and solved using a two-step Crank-Nicolson scheme. Under constant water supply, the Darcy velocity obtained at the upper boundary, the ...
