This study is based on multiple data including satellite image, DEM, climate data, geological map, soil map, basin drainage map, land use and land cover map to estimate the volume of water and sediment yield that can Kani Ban basin to convey Tanjero basin. The Soil Water Assessment Tool (SWAT) was used to achieve the aims of the study. The results showed that the rainfall on the study area is estimated at about 380 mm, while rates of runoff ranged between (73.16-151.18 mm). The percolation rates ranged between (117.48-195.94mm) and high values were concentrated in the northern and southern parts of the basin. Sediment yield was calculated using modified soil erosion equation, total amount of sediment ranged from (0.03-2.43 t / ha), at a rate of (1 t / km2). The water yield of the valleys ranged from (140.76 to 200.84) mm, where the water yield within secondary basins ranged from (120.25 to 214.95 mm).
