Résumé
Evaporation in the open water surface leads to the loss of large amounts of water in nature, so it is necessary to estimate and know these lost quantities, our study aims to compare the results of the evaporation estimate in several different ways (evaporator Piche ; Colorado pan ; Boutoutaou formula ; Penman formula), where we seek through this thesis to solve the problem of the lack of evaporation gauges or lack of data at meteorological stations, One alternative is to integrate methods using fewer variables, and the results of the study obtained showed that out of six equations, the best three were retained with validation and is : (1) E piche = 0,9105 E pan - 8,2265 sig = 0.335 (2) E Boutoutaou = 0,8561 E piche + 3,9264 sig= 0.278 (3) E penman = 1,2024 E pan - 9,7771 sig = 0.278 enabling us to calculate the evaporation value in one of the previous methods in the absence of the other.
