Analysis on the Variation Characteristics of Rainstorm and Cause of Flood in Central Yunnan — Take Downtown of Yuxi City as an Example
Published 2021-01-01“…Taking the downtown of Yuxi as an example,based on the maximum 1h and 24h rainstorm data of Dongfeng station from 1981 to 2019,this paper studies the variation characteristics of short-duration rainstorm in central Yunnan by the linear moving average,Mann-Kendall test and Hurst index,analyzes the causes of urban flood and puts forward countermeasures and suggestions.The results show that:The annual maximum 1 h and 24 h precipitation in downtown of Yuxi presented an insignificant fluctuation and rising trend,with the change rate of 1.4 mm/10a and 0.6 mm/10a respectively.The Hurst index of maximum 1 h and 24 h precipitation over the years is 0.57 and 0.56 respectively,which is consistent with the trend of future changes and relatively weak in continuity.The maximum 1 h precipitation sequence of the Dongfeng station changed suddenly in 1987,2002,2007 and 2013,while the maximum 24 h precipitation sequence changed suddenly in 2000,2009 and 2013.The annual maximum 1 h and 24 h precipitation mostly occurred in August and June,with a high concentration of rainstorm.The average P<sub>1h</sub>/P<sub>24h</sub> of the same rainstorm was 47.2%,and the largest proportion was 71.4%.Based on the causes of flood,it is suggested to regulate the river system,improve the pipe network,build new rain and sewage pipe network,construct the sponge city at all areas,and establish a scientific hydrological monitoring system and prediction and early warning platform for urban flood control and drainage.…”
