Richard's equation governs the migration of moisture in the soil under unsaturated
conditions. Although this differential equation provides a rigorous approach to simulating …

Based on the homotopy analysis method (HAM) and the generalized Coiflet-type orthogonal
wavelet, a new analytic approximation approach for solving nonlinear boundary value …

We propose a model to simulate infiltration into heterogeneous soils, with arbitrary initial
water content distributions, subject to unsteady rainfall, and under the free draining …

An analytical model based on Richards equation is presented to describe water content
redistribution during evaporation. Exponential functions are utilized to describe the relation …

A wide range of technologies is presently available for the remediation of contaminated
soils. The optimal selection depends on a number of soil characteristics. However, if the …

The large deflection of a circular thin plate under uniform external pressure is a classic
problem in solid mechanics, dated back to Von Kármán [1]. This problem is reconsidered in …

The present paper applies a simplified Green-Ampt (GA) infiltration model for the numerical
modelling of seepage processes within the body of the Maga earth dam, located in the Far …

Abstract A Moving Multi-Front (MMF) method is developed and tested for solving the
Richards equation governing unsaturated flow in vertical homogeneous porous columns …

We propose a method for the estimation of time dependent distributions of pressure head,
water content, and fluid flow in homogeneous unsaturated soils with unknown lower …

Explicit solutions to vertical and horizontal displacements are derived for large deformation
of a cantilever beam under point load at the free end by an improved homotopy analysis …
