Abstract: Flood flow patterns in mountain valleys may be influenced by longitudinal variations in channel and valley morphology and by temporal variations in boundary conditions. This study utilizes a 2-dimensional depth-averaged finite-element model (RMA2) to explore the sensitivity of flow patterns to valley bends and constrictions and flood-induced geomorphic changes at a site along the South Branch Potomac River in West Virginia.
