- Abstract
With climate change, many places have experienced extreme heavy rain and flood recently, which has a certain impact on the design flood in local areas. After analyzing the characteristics of extremely heavy rain and flood in 2010 and 2021 at Liqingdian Station in Nanzhao, Henan Province, this thesis determines the return periods of two major floods in 2010 and 2021 by using the flood data of regional survey. The design floods of various schemes are analyzed and calculated, including different flood series and historical flood recurrence periods at Liqingdian Station. According to the results, after the major floods in 2010 and 2021, the design peak flow of each frequency increased by 3.2% to 50.1%, and the design 24-h flood volume increased by 9.4% to 42.2%. The recent major floods have a significant impact on the design flood of Liqingdian Station. Therefore, the analysis and calculation of design flood should be made based on the full use of heavy rain and flood that have occurred and the surrounding survey data to fully demonstrate and determine the design flood.
