| Abstract: | Hai River Basin in the North China Plain is suffering from a serious shortage of water resources. The two major water balance components of the basin are precipitation and evapotranspiration (ET). Only the reduction of comprehensive ET can restore the water balance, and resolve gradually the shortage of water resources in the Hai River Basin. SEBAL uses spectral radiances recorded by satellite-based sensors, plus ordinary meteorological data, to solve the energy balance at the earth's surface. The latest version of SEBAL will be used in the Hai River Basin to evaluate ET. This will provide a reference for the application of basin scale water management interventions in the near future. |
