Abstract: Two-dimensional distributed finite element (F-E) and finite difference (F-D) models are developed to simulate storm events on arid watersheds. The F-E model uses the kinematic wave approximation, while the F-D model uses the diffusive wave approximation. Both formulations offer tremendous flexibility in the analysis of surface runoff generated from both stationary and moving storms. In general, F-D models offer more stability than F-E models. Input data can be obtained from a network of raingages or from radar measurements. Several raingages provide ground truth information on precipitation, while radar data describes spatial variability.
