Abstract
With the frequent occurrence of extreme rainfall events worldwide, the problem of floods and water disasters has become increasingly prominent. During the construction of engineering projects, it is necessary to fully analyze the situation of regional floods and water disasters, provide a basis for the design of flood control and drainage plans for the main project, and ensure the safety of project operation. Taking Beihai Airport Project in southern China as the study area, this paper analyzes the flood situation in the project area under the condition of 100-year return period design flood and the condition of 100-year return period design flood plus 100-year return period design rainstorm. Modelling results showed that the submerged depth within the site range from 0 to 1.32m, Distributed in the southwest, central, and eastern parts of the airport area. The tributary of Hougang River passes through the airport construction area, when encountering a 100-year flood, The flood will overflow the riverbank and enter the airport construction area. Flood prevention measures need to be considered during airport construction. This study provides a basis for the design of airport flood control and waterlogging drainage scheme, and also provides a reference for the analysis of waterlogging impact of similar projects.
