Host: 34th Conference on Hydrology
Chair:

The connection between extreme rainfall and hydrologic extremes seems obvious, but recent research has shown the relationship to be complex and location-specific.  New observing technologies and real-time hydrologic models are improving our ability to monitor and predict droughts and floods.  Meanwhile, broad-brush assumptions about climate-driven trends in frequency and intensity of hydrologic extremes fail to capture the interplay between location characteristics, meteorology, soil conditions, and vegetation.  This session invites papers on all aspects of extreme rainfall, including their relationships to floods and to the termination of droughts, encompassing observations, modeling, short-term and seasonal prediction, climate change, and risk assessment.  Papers exploring the causes and consequences of individual extreme rainfall events that cause floods or terminate droughts, as well as the causes and consequences of changing drought, extreme rainfall, and flood risk are particularly encouraged.
