Title: SEBAL Model and Its Application in the Study of Regional Evapotranspiration
Abstract: Evapotranspiration is an important parameter in the balance of the earth's surface energy and water, the development of remote sensing has promoted the study of regional evapotranspiration. Based on the equation of the balance of energy, using remote sensing data including VIS/NIR/TIR and a few of weather data, the SEBAL model can calculate the daily regional evapotranspiration. In this paper, theory?flow and method to retrieve main parameters of this model are expresses in detail, using Landsat7 ETM~+ data and SEBAL model, the evapotranspiration of Luancheng County in Hebei Province is studied, we got several surface character parameters and evapotranspiration map in one day. Adopting P-M equation, the quantity of evapotranspiration is 5.64 mm·d~(-1),the quantity evapotranspiration in sullage-irrigation area retrived from model is 5.4~7.4 mm·d~(-1),because the soil water and crop situation in sullage-irrigation area are better than others,it shows the result of simulation is in reason.
