- Abstract:
- With the continuous promotion of green development concept in cities of China, in order to scientifically support the preparation of sponge city planning, a mathematical model of water quantity and water quality in Canghai Lake, Wuzhou was established by using InfoWorks ICM and combining relevant research experience at home and abroad and local measurement parameters. Two scenarios of dry season and rainy season were designed to simulate the runoff scour effect of pollutants in Canghai Lake catchment and the migration and diffusion of pollutants in the lake, respectively, and the evolution process of surface pollutants entering Canghai Lake with rainwater runoff and diffusing in the lake under different design scenarios were calculated. Based on the calculation results, engineering guidelines and suggestions were proposed to improve the hydrodynamic conditions and protect the water quality of Canghai Lake, so as to provide reference for application of mathematical model of water quantity and water quality in sponge city planning.
