Research Area: Stormwater

Our Objective

WE&RF will evaluate how stormwater best management practices (BMPs) can affect water quality in streams, rivers, lakes, estuaries and other water bodies. We will provide simple spreadsheet screening tools as well as more comprehensive model-based products that stormwater managers, consultants, and others can use to make decisions on selection and design of effective BMP systems that achieve measurable improvements in water quality.
