Abstract

Long-term trends, and the abrupt changes of hydro-climatic variables were investigated (in the observation period of 1971-2000) for Aidoghmoush BASIN, employing Mann-Kendall nonparametric test, and cumulative curve of climatic variables-runoff, respectively. Results indicate a decrease in trends for rainfall and for runoff versus an increase in the trend for temperature as by the Mann-Kendall test (with a confidence level of 99%). Change of cumulative curve gradient of climatic variability-runoff indicates that the relationship among the parameters of climatic variables-runoff could be affected by human activities. With an identification of curve gradient change point, the observed period was divided into two sub-periods, namely: base line period and period associated with human activities. To determine the effects of human activities on runoff, hydrological model was calibrated and verified (within the baseline period), and by an introduction of hydroclimatic parameters (within the period associated with human activities) to the model, the produced runoff was estimated. The results reveal that contributions of climatic variability and human activities to the decrease in runoff amount to 79 vs. 21%, respectively.
