The problem of vertical one-dimensional infiltration for both ponded and constant flux boundary conditions was studied through the use of existing analytic solutions. Main objective was to compare the soil moisture profile developed under constant flux boundary condition at the time of ponding<InlineEquation ID="IE1"> <EquationSource Format="TEX">...</equationsource></inlineequation>

In the present work, the effect on the soil moisture profiles development and the cumulative infiltration when three different equations for calculating the diffusivity versus volumetric water content, D(θ) function, from one-step outflow experimental data are used, is investigated. These D(θ)...

A simplification for the variable sorptivity infiltration equation of Poulovassilis et al. (1989) is proposed. The resulting equation has three parameters S <Subscript>x</Subscript>, c and K <Subscript>0</Subscript>. From these, S <Subscript>x</Subscript> and c are considered as fitting parameters and K <Subscript>0</Subscript> as a physical one. The new empirical infiltration equation...</subscript></subscript></subscript></subscript>
