Abstract

Proper management of water resources is always a matter of concern in arid regions like southern Idaho such as the Snake River basin where rainfall is limited and the moisture level of atmospheric air is below threshold level most of the time throughout a year. For the proper assessment of water resources it is necessary to quantify the Evapotranspiration (ET) loss in this region and use the available water resources efficiently. A vast quantity of water is moving in the atmosphere under the direct influence of solar energy. So, in order to characterize the behavior of the water cycle, it is important to understand the energy balance of the Snake River basin. ET is an important phenomenon in the water cycle for the estimation and evaluation of the available water resources. If we understand how ET is changing over space and time, then we can more accurately calculate the crop water requirement (CWR) at a high resolution for that region. This study can help water managers and farmers in manage water resources very efficiently. Current research has difficulty projecting how ET is going to change over different locations in the future. Therefore, through this research we are trying to understand the partition of the energy balance components and quantify them to help the water management in southern Idaho. To support this research, we will use the data from both Land Surface Hydrology Model and field observations and present the trends in surface energy balance components.
