Description:
Assessing hydrologically driven erosion at regional scales from a process-based perspective presents a significant challenge. Most regional-scale erosion assessments are based upon a simple steady-state hydrology foundation. For this study, the sediment transport version of the physics-based Integrated Hydrology Model (InHM), excited by synthetically generated rainfall, was employed to assess long-term hydrologically driven erosion for a regional-scale island boundary-value problem. The spatiotemporal dynamics of runoff generation, erosion, and deposition are illustrated through saturation, water depth, velocity, and sediment concentration results. The simulations demonstrate that process-based assessment for concept development is both feasible and tractable at regional spatial and human time scales. © 2011 John Wiley & Sons, Ltd.
