Abstract

About 36 percent of the total rainfall occurring in the country can be harvested and more than 64 percent of it is evaporated. The annual rainfall in Iran is 432 billion cubic meters in which 280 billion cubic meter return to the atmosphere, while it can be used. The other 100 billion cubic meter by appropriate methods of water harvesting can be utilized. Although the rain rarely falls in the arid areas, its volume is considerable. The studied place in this research is green zone located in the beginning of Birjand-Qaen Road, with a length of 11 km, which is executed in order to the attractiveness of the city entrance and also the relative equilibrium of humidity in the area. The new and economic resources should be applied for trees irrigation due to the climatic characteristics and water shortage. Thus, the main goal of the research is the harvesting and collecting of rain water from the road surface, with a length of 9 km and directing it to the special tank and finally irrigating the green zone. The results show that due to the monthly shortage of water and water waste in the flow path, there is a capacity of storing 10000 cubic meter water in two tanks. This amount of water will be the supplier of the water shortage in the green zone. Also for optimal use and increasing the efficiency of irrigation, a drip irrigation system was designed for irrigation of the green zone.
