Abstract

The sensitivity analysis of climatic variables show that runoff is more sensitive to precipitation than temperature. As the climatic variable (temperature or precipitation) increases, the sensitivity index also increases, but the sensitivity index of precipitation was found to be higher than that of temperature. Runoff bounds predict high increase of flow in March-April-May period and slight increase or decrease in November-December period. It was found that runoff is more sensitive to precipitation than temperature, at an average of 160% and 32% in the negative and positive changes respectively. Generally the sensitivity index gap between precipitation and temperature is 96%.
