Integrated Approach for Evaporation Assessment in Al-Wand River Basin

الملخص

Estimating evaporation is crucial for planning and developing water resource development. The study discusses fuzzy logic’s ability to model monthly pan evaporation by MATLAB for Khanaqin Meteorological Station to the period (1981-2000). The model includes monthly maximum and minimum temperatures, wind speed, and relative humidity data gathered from stations situated in Al-Wand River Basin were used as input components in the model. The fuzzy logic results were evaluated with monthly average evaporation from Khanaqin Station using the coefficient of determination (R2). The results showed a converged value between the value of evaporation between Khanaqin Station and fuzzy logic, the coefficient of determination (R2) reached to 92% with the accepted trend in monthly evaporation for twenty years
