Optimization of Stromwater System Design Scheme in Sponge City Construction of Residential Areas
[Objective] The model to optimize design of sponge city residential areas was established in order to provide beneficial support for the stormwater system design and construction such sponge city residential areas. [Methods] Based on discussions of outflow runoff coefficient
runoff pollution
and sponge facilities
and taking the minimum annual cost and maximum runoff pollution reduction rate as objective functions
a bilevel coupling optimization model of sponge city residential areas was established by nonlinear programming. Model validity was analyzed and verified by taking sponge city construction areas in a region of Hefei City as a case study. [Results] After optimization
the outflow runoff coefficients in communities A
B
and C were 0.257
0.268
and 0.303
respectively. The total cost was 1.11×107 yuan
and the annual cost was 9.87×105 yuan. The runoff pollution removal rate was 70.06%
which significantly improved the economic and environmental benefits compared with the original design scheme. [Conclusion] The application of the bilevel coupling optimization model in the design of sponge city residential areas can effectively reduce the annual cost
increase the reduction rate of runoff pollution
and make sponge city design and construction more reasonable.
