The Design Flood Calculation and Water Surface Profile Calculation for a Comprehensive Regulation Project
In order to ensure the comprehensive treatment effect of Tugou River,the instantaneous unit line method is used to calculate the flood according to the actual situation of the main stream regulation project of Tugou River in Juxian County.The data series demonstrates a high level of consistency through rationality analysis,satisfying the design flood requirements and aligning with the actual conditions of the river basin.After calculating the water surface line,it has been determined that the current ground elevation of the main stream of the Tugou River in section 0+900 to 4+260 is below the design flood level.Consequently,further excavation would significantly expand the land area,necessitating the construction of new levees.It is suggested to accelerate the implementation of the regulation project of the main stream of the Tugou River,in order to improve the flood control capacity of the river course.
