Evaporation is one of the essential resource of water loss. Various methods to estimate evaporation were introduced, which evaluation of their performances in saline water bodies is of great significant. Accordingly, the aim of this study was to use remote sensing images in evaporation estimation models for a saline water body and evaluate the results of those methods. In this regard, using Moderate Resolution Imaging Spectroradiometer (MODIS) images and meteorological data, evaporation of the Urmia lake was calculated with employing FAO56-PM, Priestley-Taylor, Kimberly-Penman, Hargreaves-Samani, and METRIC methods. Then, the spatial distribution of evaporation was estimated. The result of this research showed that the evaporation over the selected saline water surface had not same distribution and considering a value of albedo for the whole surface would be result in an error in process of evaporation estimation. The obtained result indicated that due to the considering of all effective parameter, combined methods produce reliable results compared to the other methods.
