Title

Flood Control and Water Supply for Irrigation of Green Spaces Using Urban Runoff Harvesting Management Design (Case Study: Region 22 of Tehran)

Pages

  95-109

Abstract

 Background and Objective: Urbanization and increase in imperious surfaces, in many cases, have led to increase of runoff volumes and flooding in downstream areas. One of the useful methods for reduction of flood risk in urban areas is urban runoff harvesting to be used for non-potable purposes. In this study, according to urban development in Region 22 of Tehran and increased risk of flooding, as well as the need for Green Spaces development, it was attempted to implement urban runoff harvesting to supply a part of water required the Green Spaces in this area. Method: For this purpose, Green Spaces of Region 22 were identified and then Water Requirements of different species in one year was estimated using a questionnaire filled by specialists. The annual runoff volume was also calculated. Findings: Result of the calculations showed that Water Requirement of Green Spaces is 14, 969, 534 cubic meters while the average annual runoff volume was estimated as 33, 285, 441 cubic meters. According to the results, if only a quarter of the runoff (8, 321, 360 cubic meters) is controlled by special management, it would be possible to provide 5, 55% of the water required for irrigation of Green Spaces, which is currently supplied by tankers and is costly. Discussion and Conclusion: Finally, some methods such as earth dams, Crescent-shaped stacks and diamond-shaped stacks were suggested as a good models for water harvesting in places such as Cheetgar Forest Park, Vardavard, Letman and Khargooshdare.
