Abstract

The present study attempted to investigate the trends of mean annual temperature, precipitation, and streamflow changes to determine their relationships in the upper Huai river basin. The Mann-Kendall (MK), Sen’s slope test estimator and Innovative trend detection (ITA) methods were used to detect the trends. According to the finding average annual precipitation shows a descending trend in Xiangcheng (ф=-0.33), Zhumadian (ф=-0.60), Gushi (ф=0.35), Xinyang (ф=-0.32), and Xichong (ф=-0.11) stations. An increasing trend was found only in Fuyang station (ф=1.02). In all stations, the trends of mean annual temperature in Xiangcheng (ф=0.30), Zhumadian (ф=0.45), Gushi (ф=0.45), Fuyang (ф=0.36), Xinyang (ф=0.38) and Xichong (ф=0.45) was abruptly increased. During the past 56 years, the mean air temperature has considerably increased by 1.2°C. The river streamflow showed a dramatic declining trend in all stations for the duration of the study period (1960-2016) (ф=-4.29). The climate variability in the study region affects the quantity of the streamflow. The outcomes of this study could create awareness for the policymakers and scientific community about the hydro-climatic evolutions across the study basin and become an inordinate resource for advanced scientific researches.
