Title

TREND ASSESSMENT OF EXTREAM FLOWS (LOW FLOW AND FLOOD) IN SEFID-ROUD BASIN

Pages

  215-229

Abstract

 This study performs TREND ANALYSIS of hydroclimatic varibles and their possible effects on the water resources variability. Nonparametric Mann-Kendall and spearman tests were used to investigate TREND ANALYSIS of mean annual and 24-hr maximum rainfall, flood and low flow parameters of 23 hydrometery and 18 synoptic stations in SEFID-ROUD BASIN. The results showed that mean annual and 24-hr rainfall parameters are decreasing in few stations while most of stations representing negative trend for low flow and flood time series. Applying Sequential MANN-KENDALL TEST revelad that this negative trend is started from 1965 to 1970 for rainfall parameters and from 1970 to1980 for flow (low flow and flood) parameters. Results show that CLIMATE CHANGE has probability affected variability of climatic variables, while changing of land use may have aslo affeteced extreme flow trends during recent decads. Therefor it can be noted that combination of climate chanege effects and human activities on water recources have affected the negative trend of hydroclimatics variables.
