Abstract

Evaporation from the soil surface has a significant role in hydrological cycle in nature, especially in arid and semi-arid regions. In these regions the main part of water which enters the soil, reaches the atmosphere by evaporation from the soil surface. The accumulation of salts in soil surface also occurs in regions with a high water table because of evaporation from the soil surface. The main difficulty for estimating the evaporation in field conditions is lack of simple relations with minimum input data. The goal of this study is to introduce an applied relation for calculating evaporation from the bear soil with the initial and real boundary conditions using a numerical, one dimensional and non-steady analysis for regions with deep ground water surface. Since the ground water is deep, a physical model can not be applied. In real conditions, computer model LEACHM was applied as a device for NUMERICAL SOLUTION of Richards' equation with initial and boundary conditions different from the previous examinations. Since this model required much entrance data, it was determined in laboratory and field, and the model was implemented there. The influence of changing entrance data on evaporation from the soil was examined and an applied relation for calculating evaporation from the soil with different initial and boundary conditions was given. The results of given relation have a good correlation with the computer model and water balance model done by filed examination. At first evaporation depth is calculated by which the final amount of evaporation for the distinguished period is determined. Another result of this examination is to introduce a relation for calculating the accumulated evaporation in a specific day by evaporation of the first day and final evaporation of the distinguished period.
