Abstract

In this study, monthly and annual mean discharge records of Latian basin are analyzed. The Kendall-tau test is first used to detect the trend of discharge, temperature, and precipitation records. Then the correlations between these parameters are determined. Models for annual mean discharge and daily mean discharge in each month are generated based on this information using linear regression. The results show that despite the increasing trend in temperature, there is no significant trend for the annual discharge during the past four decades. Due to the increase in temperature the amount of monthly discharge has increased in cold seasons and decreased in warm seasons during the past four decades.
