Monitoring ET with Remote Sensing and the Management of Water Resources on a Basin Scale

[ABSTRACT] The shortage of water resources is serious in Hai River Basin. Managing water resources on the basis of evapotranspiration (ET), retrieved mainly from satellite remote sensing, is a new approach introduced in the GEF Hai Project. The most popular remote sensing algorithms in the retrieval of ET are reviewed, among them the SEBAL (Surface Energy Balance Algorithm for Land) is used for a preliminary analysis. Data from the MODerate resolution Imaging Spectroradiometer (MODIS) and Landsat TM/ ETM+ have been used to evaluate daily, seasonal and annual ET per county and per land use category. ET distributions and other related results for the Hai Basin, 2002 and 2003, are presented. Further studies will be continued in next five years, with an independent validation program to check and improve the ET retrieval algorithm. It is aimed to obtain a real saving of water resources through an ET reduction strategy, having more water resources remaining in the basin for production and environmental use, including that more freshwater discharge into the Bohai Sea.
