排水系统管理者面临的一个问题是极端降雨事件的增加，这种事件在世界各地都在增加。它们的发生在排水系统中造成水力超载，从而导致洪水。调整现有的基础设施，使其能够在不给城市居民造成后果的情况下接收极端降雨，已成为一种必要。这项研究显示了一种以最小的投资成本改善排水系统的新方法，为此使用了一种新的方法，考虑在管网中加入水力控制元件，安装雨水箱和更换管道。该方法采用雨水管理模型对管网进行水力分析，并采用改进的遗传算法对管网进行优化。在这种称为伪遗传算法的算法中，染色体的编码是积分的，并已被用于以前的水力优化研究中。这项工作评估所需基础设施的成本和洪水造成的破坏，以找到最佳解决方案。这项研究的主要结论是，纳入水力控制可以降低管网改造的成本，降低洪水水位。
A problem for drainage systems managers is the increase in extreme rain events that are increasing in various parts of the world. Their occurrence produces hydraulic overload in the drainage system and consequently floods. Adapting the existing infrastructure to be able to receive extreme rains without generating consequences for cities' inhabitants has become a necessity. This research shows a new way to improve drainage systems with minimal investment costs, using for this purpose a novel methodology that considers the inclusion of hydraulic control elements in the network, the installation of storm tanks and the replacement of pipes. The presented methodology uses the Storm Water Management Model for the hydraulic analysis of the network and a modified Genetic Algorithm to optimize the network. In this algorithm, called the Pseudo-Genetic Algorithm, the coding of the chromosomes is integral and has been used in previous studies of hydraulic optimization. This work evaluates the cost of the required infrastructure and the damage caused by floods to find the optimal solution. The main conclusion of this study is that the inclusion of hydraulic controls can reduce the cost of network rehabilitation and decrease flood levels.
