Movement of Sediment Accumulations
Publication: Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges
Abstract
When dams are removed, the impacts from the erosion and transport of reservoir sediment are often the primary concern. Predicting the sediment impacts is critical to ensure that the dam is removed in a safe, controlled manner and the downstream mitigation or protective measures can be appropriately designed. However, because of the limited data and inadequate models, the quantification of sediment impacts is subject to great uncertainty. A diffusive wave model of downstream aggradation is presented that may simplify the analysis of deposition of coarse material downstream. The diffusive wave model is tested against two sets of laboratory data and a one-dimensional sediment transport model (GSTAR-1D).
