Understanding the impacts of compound and cascading event on water resources management. Invited Paper 407719
Abstract
Water resources management agencies in the US such as the US Army Corps of Engineers (USACE) have addressed various impacts of climate change including rising sea levels and changes in drought or flood occurrence and severity. The USACE has also encouraged the consideration of cascading impacts related to both climate hazards and the management actions taken to prepare or respond to these hazards. Recent analyses have highlighted several types of compound events impacting USACE water resources management. Among these are coastal storm surge associated with heavy precipitation causing riverine flooding, atmospheric river events occurring during drought, and the combination of heat, drought, desertification, wildfire, and intense precipitation that increases flooding and alters sedimentation processes impacting reservoir storage. Advances in understanding compound events and cascading impacts can improve climate preparedness and response and help to avoid adverse unintended consequences of management actions. Although still a relatively recent topic area this paper provides an overview of current USACE activities related to compound events and cascading impacts. Based on lessons learned from these experiences, we identify progress and opportunities for improvement for water resources management agencies dealing with compound events.
