In this thesis, the Hydrological Simulation Program-Fortran (HSPF) was employed for estimating sediment loads and stream flows from the defined watershed areas adjacent to the HSC. Temporal and spatial analyses were performed to characterize the modeled watershed areas. The model was calibrated and validated to hourly observed flow and total suspended solids (TSS) data. Sensitivity analyses were also conducted to determine the model’s response to changes in certain hydrological and sediment parameters. The overall results indicated that the model was generally able to simulate stream flow and sediment yields well during the calibration/validation periods.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
