Abstract

The sediment-transport version of the Integrated Hydrology Model (InHM) is further tested for the case of multiple-species sediment transport with both rainsplash and hydraulic erosion using data from the Johansen et al. (2001) field experiments. The ability to simulate sub-plot scale interactions between surface water hydrology and multiple-species sediment transport with InHM is clearly demonstrated. Sensitivity analysis reveals that the erodibility coefficient has a substantial impact on the simulated total sediment mass. New spatio-temporal, data-rich field experiments are needed to continue the evaluation of the sediment-transport version of InHM and, subsequently, fully exploit the concept-development capabilities of the model.
