This Editorial presents a representative collection of 15 papers, presented in the Special Issue on Advances in Modeling and Management of Urban Water Networks (UWNs), and frames them in the current research trends. The most analyzed systems in the Special Issue are the Water Distribution Systems (WDSs), with the following four topics explored: asset management, modelling of demand and hydraulics, energy recovery, and pipe burst identification and leakage reduction. In the first topic, the multi-objective optimization of interventions on the network is presented to find trade-off solutions between costs and efficiency. In the second topic, methodologies are presented to simulate and predict demand and to simulate network behavior in emergency scenarios. In the third topic, a methodology is presented for the multi-objective optimization of pump-as-turbine (PAT) installation sites in transmission mains. In the fourth topic, methodologies for pipe burst identification and leakage reduction are presented. As for the Urban Drainage Systems (UDSs), the two explored topics are asset management, with a system upgrade to reduce flooding, and modelling of flow and water quality, with analyses on the transition from surface to pressurized flow, impact of water use reduction on the operation of UDSs and sediment transport in pressurized pipes. The Special Issue also includes one paper dealing with the hydraulic modelling of an urban river with a complex cross-section.

城市水网建模与管理进展

本社论收录了 15 篇具有代表性的论文集，这些论文发表在《城市水网建模和管理进展特刊》(UWNs) 中，并将它们纳入当前的研究趋势。特刊中分析最多的系统是配水系统 (WDS)，探讨了以下四个主题：资产管理、需求和液压建模、能量回收以及管道爆裂识别和泄漏减少。在第一个主题中，提出了网络干预的多目标优化，以找到成本和效率之间的权衡解决方案。在第二个主题中，介绍了模拟和预测需求以及模拟紧急情况下的网络行为的方法。在第三个话题中，提出了一种用于输电干线中泵作为涡轮机 (PAT) 安装地点的多目标优化方法。在第四个主题中，介绍了管道爆裂识别和泄漏减少的方法。至于城市排水系统 (UDS)，探索的两个主题是资产管理、系统升级以减少洪水，以及流量和水质建模，分析从地表到加压流的过渡，减少用水量的影响UDS 的运行和承压管道中的泥沙输送。特刊还包括一篇关于复杂横截面城市河流水力建模的论文。至于城市排水系统 (UDS)，探索的两个主题是资产管理、系统升级以减少洪水，以及流量和水质建模，分析从地表到加压流的过渡，减少用水量的影响UDS 的运行和承压管道中的泥沙输送。特刊还包括一篇关于复杂横截面城市河流水力建模的论文。至于城市排水系统 (UDS)，探索的两个主题是资产管理、系统升级以减少洪水，以及流量和水质建模，分析从地表到加压流的过渡，减少用水量的影响UDS 的运行和承压管道中的泥沙输送。特刊还包括一篇关于复杂横截面城市河流水力建模的论文。
