【 摘 要 】

Water is one of the most importantnatural resource and assessment of the trends in water has a great importanceto estimate the future of water resources. The main purpose of this study is topresent a trend analysis of the streamflow of Daday Stream in Kastamonu, Turkeyby monthly, seasonal and annual analyses. Monthly streamflow data were obtainedfrom streamflow gauging station on the stream between 1988 and 2007. Trends ofmonthly, seasonal and annual runoff of Daday Stream were analysed by Trendanalysis, non-parametric Mann-Kendall and Spearman tests. The results showedthat mean annual streamflow of Daday Stream has a significant tendency to decreasefor this period (p<0.01). Seasonal trend analysis results demonstrated statisticallysignificant decreasing trends were found for all seasons. Trend analyses formonthly displayed that there were also statistically significant decreasingtrends for all month excluding February, March, April, and June. In conclusion,decreasing trends in the streamflow of Daday Stream have been predicted forthis period and for the future. The fluctuation in water resources could beaffected by some reasons such as decreasing rainfall, rising temperaturedepending upon climate change.
