On a watershed scale, factors contributing to flooding include the total volume of stormwater, the peak flow and the duration of peak flow.
On a watershed scale, factors contributing to flooding include the total volume of stormwater, the peak flow and the duration of peak flow.
All low impact development facilities can help to prevent flooding by providing watershed distributed stormwater storage, and most feature some form of peak flow control device at the outflow or [[overflow]]. The limiting factors in the contribution that a system can make to flood control include the total storage and [[drainage time|the rate at which the system can be emptied between events]].
