Abstract

This research was conducted to determine the need for green water space in District 4 of Tehran Municipality and to calculate the required water resources for the total green space of the region. To determine the water need of green space plants, the California method (Wucols) was used and to calculate the evaporation and suspension of reference and the amount of more load, the climatic data of the North Tehran Meteorological Station in a period of 30 years (1986-2016) was used. The net area of green space in the study area was 5683 hectares, which includes 215. 20 hectares of urban Park, 5311. 73 forestry and 156. 3 hectares of other green space divisions. Irrigation efficiency in this area was estimated at an average of 35 percent. The results showed that the amount of water required annually for irrigation of green space in the area was estimated at about 48. 6 million cubic meters with an efficiency of 35 percent and about 47. 3 million cubic meters with an efficiency of 45 percent. With the scenario of increasing irrigation efficiency by only 10%, 1. 3 million cubic meters per year, only water resources were saved. According to the amount of water that can be extracted from regional water resources, which is equal to 23. 62 million cubic meters per year, the annual water shortage of the region is calculated and its amount is equal estimated to 24. 98 million cubic meters with an efficiency of 35% this requires careful management and immediate operational solutions.
