- Abstract
Estimation of evaporation from three models namely: Penman, Priestley-Taylor, and Linacre for calculating evaporation rate were compared with the observed values of data collected from pan evaporimeter. Based on two years data, the most promising and reliable model for Algardabiya reservoir in Libya has been established. Various statistical measures such as RMSE, MBE, R2 and t test have been chosen for performance evaluation of these models. The study revealed that the models resulted in reasonable accuracy. The errors in the model prediction were 2.95, 1.68, and 1.15 (mm/d) for Penman, Priestley-Taylor, and Linacre models, respectively. Linacre model, which requires only temperature data, was found to be the most reliable.
