متن کاملRainwater harvesting: A gardening necessity in semi-arid regions
This research aims to introduce the water supply method required for pistachio orchards in semi-arid climatic regions using the rainwater harvesting technique. For this purpose, a rain catchment system with an area of 1000 m2 was constructed at the Tasuj Station site. Based on the mean annual rainfall of the region, runoff threshold, runoff coefficient for insulation surfaces and the area of th...
