In a recent paper, Govindaraju and Koelliker used the Boussinesq equation to describe the horizontal one-dimensional flow of water into an unconfined aquifer from a channel. An improved analytical approach is suggested both for constant and time depe

The spatial variability of soil hydraulic properties that govern infiltration were investigated at two sites in the Konza Prairie Research Area in Kansas. One site was a pristine prairie site with native grass, and the other was a continuously croppe

A general analytical solution to the equation describing purely convective vertical transport of a conservative solute under transient water flow conditions is presented. Richards equation does not yield analytical solutions for the flow field, excep

This study addresses the development of probability distributions of travel times for one-dimensional (vertical) solute transport in soils. The field-scale soils are considered heterogeneous, with stationary fluctuations of soil hydraulic properties

A physically based model was developed for analyzing the movement of colloidal clay particles in laboratory soil columns. The physical mechanisms of detachment of particles from the soil matrix, their subsequent transportation in the pore water, and

Laboratory soil-column experiments were conducted to study the distribution of preferential flow paths resulting from removal of colloidal-size clay particles. Flow paths were assumed to result when the fluid energy was able to overcome the cementiti

A theoretical solution framework to the nonlinear stochastic partial differential equations (SPDE) of the kinematic wave and diffusion wave models of overland flows under stochastic inflows/outflows, stochastic surface roughness field and stochastic

Following the study of Govindaraju et al. (1988), approximate analytical solutions are presented to the diffusion and kinematic wave models subject to space and time-varying rainfall. An approximation in the form of the first term of an infinite sine
