Analysis of Multi-Scale Flood Series Alteration in the East River Basin
Abstract: Under the influence of climate change and human activities, alterations may happen to the distri-bution regulations and parameters of flood series in the East River basin. In order to uncover the multi-scale flood series alterations on temporal and spatial scales, annual maximum 1-day, 3-day, 5-day and 7-day floods of the Longchuan, Heyuan, Lingxia and Bolo stations in the East River basin were chosen, then the hydro-logical alteration diagnosis system was used to analyze the alteration. Combining with the analysis of the in-fluence of climate change and human activities such as the alteration of precipitation series and water con-servancy facilities in the East River basin, the physical causes of flood alteration are mainly due to the cas-cade hydropower plants. Results indicate that the variation degree of annual maximum 1-day, 3-day, 5-day and 7-day floods at the Longchuan, Heyuan, Lingxia, and Bolo stations are different. It is shown that the re-lationship between stations is different and the influence of climate change is very little.
