12/06/2019 · Two-dimensional (2D) numerical models are useful tools for studying river morphology. Frequently, 2D numerical models are often applied to predict the impacts of the artificial changes to rivers and estuaries. These changes may be caused by altered watershed hydrology, variations in the sediment supply and the construction of artificial works such as dams, embankments and tidal gutters. The
In this case, “common sense” means a background in sediment transport problems, which is sufficient for you to be able to check whether the results are reasonable or not.
