Multidimensional infiltration with arbitrary surface fluxes

A new solution to the multidimensional linearized Richards equation was der ived using a Fourier integral transform. Exponential functional forms k = k (s)e(alpha psi) and theta = theta, + (theta (s) - theta (r))e(alpha psi) we re used to represent the hydraulic conductivity and pressure relation and t he soil water release curve. The analytical solutions consider the conditio ns of time dependence and nonuniform distribution of rainfall intensity and arbitrary initial water content distribution with a water table. The analy tical solutions can be used to predict the ponding time and to obtain the v olumetric water content distribution over time and space.
