Using Inverse Modeling by HYDRUS-1D to Predict Some Soil Hydraulic Parameters from Soil Water Evaporation

The objective of this research was to assess the use unsaturated water flow in terms soil evaporation, which determined by evaluating some hydraulic parameters different textures. results show that predicted values these parameters, were obtained through inverse modeling with HYDRUS-1D software and depend on change volumetric content, exhibited a significant agreement measured from laboratory or field simulation data for evaporation at 5. 10. 20. 45 days measurement. At same time, conducted 5-day period predict infiltration retention curve, showed all
