Study about Realizability Situation and Utilization Contexts of Water Sensitive Urban Design

Climate changes, failure to complete the natural cycle of water in the city due to unsustainableconstruction of the urban environments and increase of impervious surfaces, lack of nutrition of undergroundaquifer in the cities, unsustainable management of stormwater and the floods due to them in the periods of rainfallcaused to provide an approach that is called water sensitive urban design. This approach offers methods in the threeparts; Sustainable management of stormwater, domestic scale water management and wastewater management.Different countries have pay to utilize of these methods according to their climatic conditions and their urbanforms each in different ways. This study shows for achieve success in use of WSUD methods we need situation andrequirements such as: Legal framework, ability of methods to close water cycle in cities to natural water cycle, payattention to aesthetic concepts and aspects, methods ability to achieve the technical objectives, pay attention to typeof methods and the scale of site, pay attention to climate conditions and specifications in implementation of projects,the measure of selected methods efficiency, public acceptance and integrated planning in the projects.
