Water Sensitive Design Strategies In High Density Residential Areas

To solve this problem of the process of urbanization in urban settlements "dry" and "more water" and proposed sponge urban construction mode, the concept of water-sensitive urban design is based LID thinking evolved, both in substantially similar to the core measures. Water-sensitive urban design systems with strong guidance on urban design method, this article will water sensitive urban design concept of the system and the "sponge City" requirements in the guidelines combine investigate high density residential water sensitive design policy, promote "sponge settlements" universal.Firstly, on the scope of the study the meaning of "high density" content made defined. Summarizes the existing settlements rainwater Ecological research design approach, drawing on the successful practice case settlements, the integration density of a conventional settlements, water sensitive technical measures and the elements of buildings, roads, site and landscape design combined method. Further analysis of the high-density residential water sensitive design to construction, all aspects of inter-house, landscape, traffic space is different from the characteristics of conventional settlements conditions, starting from the specific issues, reverse thinking, the conditions for the corresponding feature to discuss their specific the way to deal with the practice of selecting a conventional method applicable portion inquiry response program does not apply in case. Make full use of high-density settlements in terms of water-sensitive design advantages, resolve its restrictive conditions. Final draw set for high-density settlements, water sensitive design strategies and applies comprehensive real cases. Popularizing "sponge City" technical guidelines in China’s high-density Residential building ecological stormwater management has a positive role in promoting.In this study, water-sensitive urban design (WSUD) as practical guidance, refer to "Technical Guide sponge Urban Construction-Construction of low-impact development stormwater systems," the specific requirements involved in the design of residential stormwater management, according to the existing settlements ecological rainwater research management design methods, sorting out the conventional residential water sensitive design objectives, principles, processes and specific practices. Depth study of conventional residential water sensitive design methods, analyzing the impact of high-density residential water sensitive design features based on the conditions on the choice of routine precautions settlements water sensitive design methods will be described, is not it suitable methods vary, refined water sensitive design in high density settlements operations and implementation methods, and ultimately proposed high-density settlements specific adaptive design strategies.In order to clearly state and contrast conventional settlements and high-density residential water sensitivity design of specific methods, this article with the same first 150 m by 200 m plot design general residential density and high density residential respectively, combining with the example given corresponding design strategy. Finally combining simulation design-yangzhou tang wang garden plot comprehensive residential design for actual application study, on the control of the key indicators. Through practice of specific methods to illustrate the high density residential water sensitivity design adaptive strategy.
