摘要：The past drought in Ethiopia had resulted in a massive loss of vegetation as well as loss of soil within th~ watershedsof the Blue Nile and Atbara Rivers. The objective of this research is to develop sediment-yield model forthe Blue Nile Basin by using the Advanced Very High Resolution Radiometer (AVHRR)-NOAA satellite Data.The Global Vegetation index (GVI), which determined from the Normalized Difference Vegetation Index (NOVOusing the AVHRR sensors, will be inserted as a major factor into the hydrologic regression sediment-yield modelestablished for the Blue Nile Basin. This approach to predict sediment yield is very economical and gives a satisfactoryresul ts
