A time-dependent water infiltration problem in homogeneous soil with water absorption is
considered. The problem involves infiltration from periodic trapezoidal channels. Four …

In this paper, some steady infiltration problems from periodic channels into two-layered soils
are considered. The problems are governed by a system of Richards' equations with …

In this paper, problems involving steady pollutant spread from a point source in a path with
laminar water flow are studied. Three different paths with different inclination angles are …

This study delves into the investigation of steady infiltration problems within a two-layered
soil, featuring periodic channels, and taking into account the presence of rootwater uptake …

This paper investigates steady infiltration problems involving periodic channels in two-
layered soil with the presence of root-water uptake. The problems are governed by a set of …

In this paper, problems involving steady heat conduction in two-layered materials are
