Managing excess or concentrated stormwater runoff from urban and peri-urban catchments can be an important management opportunity. There are several terms to describe these activities, including Integrated Stormwater Management (ISWM) or Water Sensitive Urban Design (WSUD). Urban stormwater runoff can be more than 10 times pre-development volumes and can have significant geomorphic impacts. Intervention approaches include stormwater control measures such as constructed wetlands, raingardens and stormwater tanks.
ISWM/WSUD involves maximising the retention or detention of stormwater and releasing it more slowly and in less concentrated flows. There are many different techniques, often used in combination, and their placement will be highly influenced by the available space, both above and below ground. These systems can manage water volumes, treat water quality and provide amenity (see Treatment systems).
