Impact/Purpose:
The purpose of the presentation is to describe a EPA-led national effort to develop rapid tools to classify stream reaches that help implement federal, state and local programs. The presentation will provide background materials, developed examples, and status of ongoing and future work.
Description:
Streamflow Duration Assessment Methods (SDAMs) are rapid, reach-scale indices or models that use physical and biological indicators to predict flow duration class (perennial, intermittent, or ephemeral). The U.S. Environmental Protection Agency is working cooperatively with the U.S. Army Corps of Engineers and other partners across the nation to develop regional SDAMs to help implement many federal, state and local programs (https://www.epa.gov/streamflow-duration-assessment). The presentation will describe the process used to develop SDAMs, examples of regional SDAMs, and future steps to complete nationwide coverage.
