| Abstract | ||
| Unsustainable growth of cities and creation a set of contiguous impervious surfaces have result on disorder of natural cycle of water in urban environments. This situation causes flooding and problems due it, pollution of groundwater resources and degrade the quality of the urban landscape by increase the speed, volume and frequency period of runoffs. conventional methods about the stormwater management have failed to demonstrate their effectiveness in this field. Thus, in recent years a new topic are created in the field of urban design that known as "water sensitive urban design". Water Sensitive Urban Design (short: WSUD) is the interdisciplinary cooperation of water management, infrastructer engineering, urban design, and landscape designing. WSUD develops integrative strategies for ecological, economical, social, and cultural sustainability. The purpose of Water Sensitive Urban Design is to combine the demands of sustainable stormwater management with the demands of urban designing, and thus bringing the urban water cycle closer to a natural one. This approach attempts to increase urban sustainability indicators, improve the quality of urban landscape and urban space amenities by offer operational mechanisms in relation to urban design and it attempts not only to close the urban water cycle in its natural cycle and achieve technical goals, but gain optimal utilization of runoff and change the vision of the issue from a threat to a valuable opportunity.The following is a description of some essential methods for sustainable stormwater management. These methods are grouped according to their primary function: water reuse, treatment, detention and infiltration, conveyance, and evapotranspiration. Here is the techniques of water sensitive urban design about stormwater management and link them to urban design concepts, till through that some methods to be introduced that they are more efficient than conventional stormwater management methods about performance, helping to complete the natural cycle of water, environmental sustainability of cities and urban design aspects. | ||
