Runoff Variation Characteristics in Dry Season and Discharge Prediction during Ice-Covered Period at Xiabagou Station
摘要
Abstract
To investigate runoff evolution under changing environmental conditions,the Taohe river basin was selected as the study area.Based on monthly runoff data from 1964 to 2020 at Xiabagou station,statistical methods including the Mann-Kendall test were applied to analyze dry-season runoff characteristics.Two methods were used to estimate discharge during the ice-covered period.Results show a declining trend in dry-season runoff,with abrupt changes occurring in specific months.The upstream-downstream correlation method proves effective for ice-period discharge estimation.The findings provide reference for similar hydrological studies.关键词
