摘要: Land use/land cover change has been responsible for altering the hydrologic response of watersheds leading to impacting river flows. Various water resources projects’’ planning and implementation will require knowledge extent these changes on watershed hydrology. The main objective this study is assess impact land use flow Angereb which located in upper Tana basin, Ethiopia. In particular, analyses between 1985 2011, effect have had runoff reservoir inflows watershed. within were examined through classification satellite images with integrated image spatial analysis. Soil Water Assessment Tool (SWAT) model was used investigate stream flow. calibrated validated using historical data. analysis shown that cultivated built up areas increased, while forest grass decreased 2011. Sensitivity curve number most sensitive parameter affects hydrology year data from 1992 2000 2001 2004. R2 Nash Sutcliffe Efficiency (NSE) values 0.85 0.76 calibration, 0.79 0.72 validation, respectively. evaluation SWAT mean wet monthly 2011 increased by 39% compared cover. On other hand, dry average 46%
