洪水期水动力条件对人工湖沉水植物布置影响的数值模拟与优化策略研究
Numerical Simulation and Optimization Strategy Study on the Impact of Hydrodynamic Conditions During Flood Period on the Layout of Submerged Plants in Artificial Lakes
摘要
Abstract
To explore the optimization strategy for the layout of submerged plants in artificial lakes,a two-dimensional hydrodynamic model of Lingxiu Lake was constructed using HEC-RAS.Simulations were conducted for floods with return periods of 50 years,20 years,and 10 years in Lingxiu Lake to analyze the impact of flow velocity and water depth distribution during the flood period on the layout of submerged plants.Additionally,the layout of submerged plants was optimized based on the mixed planting scheme of aquatic plants.The results show that:the suitable planting area for submerged plants is the nearshore lake area where the flow velocity is less than 1.0 m/s during the flood period and the water depth at normal water level is less than 1.2 m,with an area of 24 677.5 m2;according to the suit-able planting water depth of different aquatic plants,considering the mixed planting of submerged plants with emergent plants and floating-leaved plants,the optimized planting area is 12 182.4 m2.The established hydrodynamic model is accurate and reliable,and it well simulates the hydrodynamic characteristics of the artificial lake during the flood period,which can provide technical support for the opti-mized layout of aquatic plants in similar projects.关键词
