Rainfall and ET
Rain is water droplets that condense from atmospheric water vapor and then fall under gravity. Precipitation is a major component of the water cycle and is responsible for accumulating most of the fresh water on Earth. Evapotranspiration (ET) is the combined processes by which water moves from the earth’s surface into the atmosphere. The average annual rainfall of Ayad river basin is 640 mm with CV 32.82%. The 1st highest (1222.8 mm), and 2nd highest (1184 mm) rainfall were realized during the year 1917, and 2019 respectively, while the lowest (127.8 mm) during 1938. The annual rainfall during 1917 was about 91% more than the long period average (LPA-640 mm).
