Workshop Proceeding

Flood damages have increased greatly over the past century, in part because of increased development in floodplain areas. Unfortunately, conventional methods used to understand and plan for flooding -- for example by considering flood risk when designing structures and setting insurance rates -- have become outdated. This report summarizes the discussions at a two-day workshop held by the National Research Council to foster dialogue among the science and applications communities on issues related to planning for extreme hydrologic events. Discussions at the workshop focused on research needs in the new science of hydrologic extremes, the role of new and advancing methods to observe and predict flood events, and the interface between the science of hydrologic extremes and how science information is utilized, for example, by agencies to monitor flood levels. The report highlights issues for future attention by the National Research Council and workshop participants.
