The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM) [1][2][3][4][5][6][7][8] is a dynamic rainfall – runoff – subsurface runoff simulation model used for single-event to long-term (continuous) simulation of the surface/subsurface hydrology quantity and quality from primarily urban/suburban areas.
Daylighting (streams) The daylighted Saw Mill River in Getty Square, Yonkers, New York, had been covered by a parking lot. A short stretch of Lower Marin Creek in UC Village in Albany, California has been daylighted.

t. e. Stormwater, also written storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil (infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff.
Retention basin. A retention basin, sometimes called a retention pond, wet detention basin, or storm water management pond (SWMP), is an artificial pond with vegetation around the perimeter and a permanent pool of water in its design. [1][2][3] It is used to manage stormwater runoff, for protection against flooding, for erosion control, and to ...
Storm drain grate on a street in Warsaw, Poland Storm drain with its pipe visible beneath it due to construction work. A storm drain, storm sewer (United Kingdom, U.S. and Canada), highway drain [1], surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved ...
Bioswale. Runoff from the vicinity flows into an adjacent bioswale. Bioswales are channels designed to concentrate and convey stormwater runoff while removing debris and pollution. Bioswales can also be beneficial in recharging groundwater. Bioswales are typically vegetated, mulched, or xeriscaped. [1] They consist of a swaled drainage course ...
