Selecting the best-suited model to support stormwater projects can be complicated. Today’s water quality managers must not only be able to predict peak flow rates, runoff volumes, and receiving water quality, they must also navigate stringent regulatory requirements and varying levels of resources. The Water Environment Federation’s (WEF; Alexandria, Va.) newest publication, Stormwater, Watershed, and […]
