Federal Flood Risk Management Standard Climate-Informed Science Approach (CISA) State of the Science Report

The state of the science is described in the context of four types of flooding—coastal, riverine, pluvial, and compound. This report introduces two flood hazard projection workflows that describe the elements that are recommended to be considered when applying the Climate-Informed Science Approach for coastal- and riverine-related flooding, the two flooding types where the present understanding is most mature.

These flood hazard projection workflows also provide an overarching framework for users to understand where new data and science, including new information on climate change, feed into the process of assessing and projecting future flood hazards.
