Abstract: Engineering modifications of rivers, e.g., dams or groynes, often induce long-term riverbed erosion, which can be mitigated with sediment nourishments. Here, we consider nourishments to mitigate channel bed erosion ...

Abstract: A two-dimensional, finite-difference numerical model is developed to simulate the breach evolution of noncohesive optimally compacted earthen dams. The main feature of the model is the inclusion of a source term in the ...
