Sacramento Area Hydrology Model (SAHM)
The Sacramento Area Hydrology Model (SAHM) was developed by the Sacramento Stormwater Quality Partnership (Partnership) as part of the Hydromodification Management Plan (HMP) project. This tool is intended to assist Engineers in designing BMPs that meet upcoming hydromodification management requirements and low impact development requirements. The Partnership’s proposed hydromodification management requirements are presented in the revised HMP that was submitted to Central Valley Regional Board for approval in February 2013. The HMP was finalized in December 2017.
