低影响开发 (LID) 和管道更换有效地管理城市洪水. 将LID集成到不透气的区域,并考虑25年的风暴情景,提供了最好的防洪投资.
科学领域:
- 环境工程 环境工程
- 城市规划 城市规划
- 水资源管理 水资源管理
背景情况:
- 洪水对社区和经济造成重大损害,需要有效的洪水控制和雨水管理.
- 城市环境面临越来越多的挑战,因为开发和降雨模式的变化导致过剩的水.
- 低影响开发 (LIDs) 和传统的管道更换是管理表面流水的关键策略.
研究的目的:
- 使用多目标优化 (MOO) 方法优化洪水控制策略.
- 评估LID和管道更换在各种降雨强度和未来非静止条件下的有效性.
- 为了确定成本有效的解决方案,以尽量减少地表排水,洪水地区和建筑费用.
主要方法:
- 采用多目标优化 (MOO) 方法分析洪水控制策略.
- 开发了六种经过调整的降雨强度的场景,模拟未来的非静止条件.
- 使用空间分析来评估LID放置和与管道更换整合的影响.
主要成果:
- 增加的投资显示了排水和洪水区域减少的非线性改善.
- 在不同情景中,在排水量减少和洪水面积减少之间观察到明显的趋势.
- 集群LID在不透气的区域,并将它们与管道更换相结合,被证明是有效的洪水控制.
结论:
- 25年-24小时风暴情景显示,减少洪水面积的效益成本比是最高的.
- 整合LID与管道更换对于有效的城市洪水控制至关重要.
- 结果支持城市规划人员在预算限制范围内设计可持续的排水系统和城市规划.
