Preface Red River originated in Zhanyi County, Yunnan Province, flows through Yunnan and Guangxi, Guizhou and Guangxi at the junction into Guangxi. Basin area of 130,870 km ~ 2. Since 1936, hydrological observation of main stream has set up three hydrological stations of Ding Donglan, Du’an and Qianjiang in the middle and lower reaches of the country (Figure 1). The historical flood investigation took place in Du’an Station as early as 1941 and 1948, and was liberated After that, seven or eight units successively conducted more than 20 surveys and obtained many valuable materials. However, due to the different purposes and requirements of the surveys of various units, the depth of the work varied from no comprehensive analysis of the upstream and downstream balances and the internal and external watersheds. The important historical documents and tablet data also failed to make detailed investigations and research. Therefore, the problems of the historical floods that were investigated failed to be satisfactorily solved. In 1975 our hospital accepted
