Projecting Extreme Precipitation in the Delaware River Basin
The Projecting Extreme Precipitation in the Delaware River Basin tool released by the DRBC allows users to obtain estimates of future changes in intensity, duration and frequency (IDF) curves throughout the Delaware River Basin. The curves represent how climate change could impact future rainfall patterns. They are based on regional climate models and can be plotted against historical data (Atlas 14) to compare outcomes, helping inform stormwater management and infrastructure design to increase climate resilience.
Policy and justice tools
