Abstract:

Evapotranspiration is a key process of water balance and also an important element of energy balance. Its precise estimation is not only of vital importance for the study of climate change and evaluation of water resources, but also has much application value in crop water requirement management, drought forecasting and monitoring, effective water resources development and utilization etc. Actual evapotranspiration is a key process of hydrological cycle and a sole term that links land surface water balance and land surface energy balance. The study was conducted in Shipra river basin to determine actual evapotranspiration in the area. Long term daily meteorological data including rainfall, maximum temperature, minimum temperature, relative humidity, wind speed and sunshine hours of Indore IMD station was used as input data in CROPWAT Model 8.0. The potential evapotranspiration was converted into actual evapotranspiration by using the crop coefficient. Reference evapotranspiration is a measure of evaporative demand, while the crop coefficient accounts for crop characteristics and management practices (e.g., frequency of soil wetness).The major crop in the shipra river basin area are soyabean and sorghum which are kharif crop whereas the rabi crop in the area are wheat and gram and the summer or zaid crop in the area is sunflower. The value of Kc in, Kc mid, Kc end for the selected crop was obtained from department of irrigation. The maximum average actual ET was in the month of May i.e., 288 mm due to highest temperature in this month and the minimum average actual ET was in the month of November i.e., 34 mm due to minimum temperature in this month. Thus the experiment concluded that PET and AET increases as the temperature increases and it decreases as the temperature decreases.
