Toward understanding changes in large-scale floodplain connectivity caused by levees
The widespread construction of levees has reduced river-floodplain connectivity and harmed associated fluvial processes in many river systems. Despite the recognition that levees can alter floodplain connectivity, few studies have examined the role of levees in reducing floodplain areas at large watershed scales. In this paper we explore the application of a hydrogeomorphic floodplain mapping approach in the Wabash basin, U.S. to assess floodplain loss in levee-protected areas. We evaluate 10-m and 30-m topographic resolutions and spatially examine the influence of levees on floodplain area in ...
