Changes of Runoff in Bosten Lake Basin and Annual Distribution Characteristics
Based on the monthly measured runoff data of Kaidu River and Huangshui Gulley of Tarim River Basin Administration from 1956 to 2021,the variation and annual distribution of runoff in Kaidu River and Huangshui Gulley are studied by the methods of concentration,linear regression,and Mann-Kendall rank...

| Summary: | Based on the monthly measured runoff data of Kaidu River and Huangshui Gulley of Tarim River Basin Administration from 1956 to 2021,the variation and annual distribution of runoff in Kaidu River and Huangshui Gulley are studied by the methods of concentration,linear regression,and Mann-Kendall rank test.The results show that the annual runoff of the Kaidu River and the Huangshui Gulley shows an increasing trend,and the annual runoff shows a gradual change of “decreasing,increasing,and decreasing”.The annual runoff of Kaidu River and Huangshui Gulley had abrupt changes in 1996 and 1994,respectively.After abrupt changes,the annual average runoff was higher than that before abrupt changes.The monthly runoff shows an increasing trend,and the monthly runoff increases significantly in winter.The monthly runoff distribution is unimodal throughout the year,and the annual runoff is mainly concentrated in summer,with the peak runoff in July.The mean monthly runoff after the abrupt changes was higher than that before the abrupt changes and multi-year averages.The characteristic values of each index show that the annual runoff distribution of Kaidu River has a uniform development trend,while that of Huangshui Gulley is still concentrated.The runoff of Kaidu River is mainly affected by precipitation and temperature,and that of Huangshui Gulley is mainly affected by temperature change. |
