Hydrological regimes of river system have been changing under climate change and human activities,so study on the trends of these hydrologic variables can provide references for water resource management and flood risk analysis.Xiang river,a tributary of Yangtze River was chosen to investigate the hydrological responses to climate change and human activities.Based on the site data of daily runoff and water level as well as the deduced annual,seasonal and monthly runoff and water level series over the past thirty years,a non-parametric statistical method (Mann-Kendall trend test) is employed to detect trends and abruption of runoff and water level in Xiang River Basin suffering by severe floods.
