  9. Stormwater - Wikipedia

    en.wikipedia.org/wiki/Stormwater

    This greatly increases the volume of water in waterways and the discharge of those waterways, leading to erosion and flooding. Because the water is flushed out of the watershed during the storm event, little infiltrates the soil, replenishes groundwater, or supplies stream baseflow in dry weather. [1] A first flush is the initial runoff of a ...
