Abstract:
Prediction of sediment yield from catchments is essential in the investigation of reservoir sedimentation and
other hydrological and geological studies. Many methods have been used in the prediction of sediment yield.
Soil and Water Assessment Tool (SWAT) is a newly developed model that can be applied to rural watershed.
SWAT model has used Modified Universal Soil Loss Equation (MUSLE) in sediment calculation. The
Automated Geospatial Watershed Assessment Tool (AGWA) is a GIS based watershed modeling tool. This
paper improved a hydrological modeling using modeling environment AGWA and SWAT model to evaluate the
sediment yield in Kufranja basin in Jordan. The sediment yield has been calculated at three proposed dam sites in
the basin. The calibration process depended on the most sensitive parameters in SWAT model. Long term
rainfall series were used in the modeling process. AGWA studies the change in the most sensitive parameter in
the SWAT model. The change in this parameter can be considered as different scenarios in Kufranja basin.
