Improve/Create water storage
Category 01. Water flow quantity improvement
General description
- Changes in land use and cover
- Improve stormwater management
- Reduce and limit the amount of impervious surfaces in the watershed
- • Change land use practices and zoning regulations to limit the allowable percent of impervious surface in the watershed
- • Decommission roads
- • Use pervious pavement alternatives where feasible
- Minimize the extent and degree of soil compaction
- Restore stream connectivity to floodplains (see Remove bank fixation, Allow/increase lateral channel migration or river mobility, Remeander water courses, Shallow water courses, Widen water courses, Lower river banks or floodplains to enlarge inundation and flooding, Remove hard engineering structures that impede lateral connectivity, Set back embankments, levees or dikes )
- Revegetate denuded areas within the watershed. Mean annual flow is increased as a result of greater runoff due to clearing and urbanization (Peterson& Kwak 1999)
- Protect, restore, and create wetlands and other infiltration areas (see Construct semi-natural/articificial wetlands or aquatic habitats, Improve backwaters, Reconnect backwaters and wetlands, Restore wetlands, Retain floodwater )
Applicability
Stormwater management
Stormwater reuse schemes are an effective way to reduce urban runoff volume. However, it is important to harvest only the larger flows than those occurring before the catchment was developed, to ensure that environmental flows are maintained in receiving waterways.
Expected effect of measure on (including literature citations):
- HYMO (general and specified per HYMO element)
- physico � chemical parameters
- Biota (general and specified per Biological quality elements)
Temporal and spatial response
Pressures that can be addressed by this measure
Cost-efficiency
Case studies where this measure has been applied
- Regge Velderberg
- Uilenkamp - Meander reconnection
- Sweden- Restoration of the Freshwater Pearl Mussel and its habitats (LIFE04/NAT/SE/000231)
