Effects of Morphological Change on Fluvial Flood Patterns Evaluated by a Hydro-geomorphological Model
Abstract High aggradation and degradation in a river induced by last flood event will respectively raise and decrease the risk of an upcoming flood event. However, this point is likely to be ignored or is not fully considered in some 2D fluvial...
