MOHAMMED, Esam; ABID-ALZIZ AL-QASSAB, Salahaldeen  e  SALIH AL-WAZAN, Faris Akram. Using Inverse Modeling by HYDRUS-1D to Predict Some Soil Hydraulic Parameters from Soil Water Evaporation. Colomb. for. [online]. 2022, vol.25, n.1, pp.21-35.  Epub 10-Mar-2022. ISSN 0120-0739.  https://doi.org/10.14483/2256201x.18157.

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