Description :
The physics-based model known as the Integrated Hydrology Model (InHM) is used to simulate continuous hydrologic response and event-based sediment transport for the R-5 catchment (Oklahoma). The hydrologic-response simulations were conducted in one-year periods, for a total of 6 years. Soil-water content was over-estimated during dry periods compared with the observed data. The sediment-transport simulations were more successful in reproducing the total sediment mass than the peak sediment discharge rate. The results reinforce the contention that comprehensive and detailed datasets are crucial for testing physics-based hydrologic-response models.
