The integration of nonstructural methods into flood loss reduction programs:an evaluation of a remaining obstacle
Current U.S. Army Corps of Engineers water resources planning guidance directs the planners to consider all design alternatives with economic efficiency as the primary criterion. Recent criticism of the flood loss reduction planning is directed at the Corps. One criticism is that the traditional …
