Two-Dimensional Simulation and Parameters Optimization of Soil-Water Flow from Field Experiments of M’Nasra Area (North-West Morocco)

EasyChair Preprint no. 7314

Abstract

Determination of soil hydrodynamic parameters at field scale is of great importance for modeling soil water dynamics and for agricultural water management. Modeling of water flow and solute transport in the unsaturated soils requires knowledge of many parameters associated with the water content θ(h), hydraulic conductivity K(h), The experimental determination of some of these parameters in the laboratory or in-situ requires expensive equipment and requires significant time. The main objective of this work is to optimize the hydrodynamic parameters of unsaturated soil by using  the two-dimensional numerical software HYDRSUS-2D model with different boundaries conditions at the soil surface to simulate water flow. Soil water content samples, collected from the area of M’nasra in north western of Morocco, were used to deduce the optimized values of hydrodynamic parameters   and  . The results show that HYDRUS-2D model simulated water flow through the root zone depths satisfactorily.
