Water sensitive urban design (WSUD) principles

Water-sensitive urban design WSUD is a land planning and engineering design approach which integrates the urban water cycle, including stormwatergroundwater and wastewater management and water supplyinto urban design to minimise environmental degradation and improve aesthetic and recreational appeal. Traditional urban and industrial development alters landscapes from permeable vegetated surfaces to a series of impervious interconnected surfaces resulting in large quantities of stormwater runoff, requiring management.

Historically Australia, like other industrialised countries including the United States and United Kingdom, has treated stormwater runoff as a liability and nuisance endangering human health and property. This resulted in a strong focus on the design of stormwater management systems that https://amazonia.fiocruz.br/scdp/blog/culture-and-selfaeesteem/campaign-ads-america-is-highly-familiar-with.php convey stormwater runoff directly to streams with little or no focus on ecosystem preservation.

Why do we do water sensitive urban design (WSUD)?

Increased peak flow also alters channel morphology and stability, further proliferating sedimentation and drastically reducing biotic richness. Increased recognition of urban stream syndrome in the s Adaaptation in some movement towards holistic stormwater management in Australia. Additionally, Australia's arid conditions means it is particularly vulnerable to climate change, which together with its reliance on surface water sources, combined with one of the most severe droughts from — since European settlement, highlight the fact that major urban centres face increasing water shortages. Australian states, building on the Federal government's foundational research in the s, began releasing WSUD guidelines with Western Australia first releasing guidelines in Seneitive released guidelines on the best practice environmental management of urban stormwater in developed in consultation with New South Wales and similar documents were released by Queensland through Brisbane City Council in The NWI Adaptation Of Water Sensitive Urban Design For a comprehensive national strategy to improve water management across the country, it encompasses a wide range of water management issues and encourages the adoption of best practice approaches to the management of water in Australia, which include WSUD.

WSUD regards urban stormwater runoff as a resource rather than a nuisance or liability.

This represents a paradigm shift in the way environmental resources and water infrastructure are dealt with in the planning and design of towns and cities. Usually, a combination of these elements are used to meet urban water cycle management objectives.

Bioretention systems involve the treatment of water by vegetation prior to filtration of sediment and other solids through prescribed media. Vegetation provides biological uptake of nitrogen, phosphorus and other soluble or fine particulate contaminants.

Bioretention systems offer a smaller footprint than other similar measures e. Use on larger scales can be complicated and hence other devices may be more appropriate.

Biorentention systems comprise bioretention swales also referred to as grassed swales and drainage channels and bioretention basins. Bioretention swalessimilar to buffer strips and swalesare placed within the base of a swale that is generally located in the median strip of divided roads. They provide both stormwater treatment and are. A bioretention system can be installed in part of a swale, or along the full length of a swale, depending on treatment Adapyation
