Title

SENSITIVITY ANALYSIS OF EVAPOTRANSPIRATION FOR ROORKEE, UTTARAKHAND, INDIA

Abstract

Abstracts-The need of existing water allocation in a sustainable manner with meeting the needs of the projected population growth, initiated to assess the consumptive use or evapotranspiration (ET), which ultimately determines the irrigation demand. Its estimation is very much essential in the fields associated with water resources management. ET denotes evaporative nature of the atmosphere and depends on climatic parameters like solar radiation, temperature, relative humidity, wind speed etc. Sensitivity analysis is important to understand the relative importance of climatic variables to the variation of the evapotranspiration (ET). It is done to acquire a better understanding of the climatological parameters, which particularly indicates the physical meaning of each climatic parameter used in the ET estimation. In the present study, a graphical attempt was made to predict the average percentage change in responses of ET with respect to the percentage change of the various climatic variables, obtained at NIH Observatory, Roorkee. A historical monthly dataset of average temperature, relative humidity, solar radiation, sunshine hour from 1987-2013 were used in this analysis. The graphical sensitivity analysis based on sensitivity index was done using two evaoptranspiration methods i.e., Thornthwaite and Turc method and a comparison was made among them. The results of the study showed that monthly sensitivity exhibited large fluctuations during the growing season and solar radiation was the most sensitive variable in general for the NIH, followed by mean temperature and sunshine hours. It also showed that the influence of the climatic variables to ET, is not the same for each period. Solar radiation and mean temperature are the main parameters that affect ET.

Key Words

Sensitivity, ET, Turc method, Thornthwaite method.
