This study included the extraction properties of spatial and morphological basins studied using the Soil and Water Assessment Tool (SWAT) model linked to (GIS) to find the amount of sediment and rates of flow that flows into the Haditha reservoir . The aim of this study is determine the amount of sediment coming from the valleys and flowing into the Haditha Dam reservoir for 25 years ago for the period (1985-2010) and its impact on design lifetime of the Haditha Dam reservoir and to determine the best ways to reduce the sediment transport. The result indicated that total amount of sediment coming from all valleys about (2.56 * 106 ton). The maximum annual total sediment load was about (488.22 * 103 ton) in year 1988 due to the surface runoff about 167.79 * 106  m3, while the minimum annual total sediment load was about (8.62 * 103 ton) in year 2007.  This due to the total runoff volume that was 5.67×106 m3. Model calibration and verification were carry out using flow rate and sediment yield data observed at the study area and the results were satisfactory.
