Numerous countries and regions have embraced implementing a separate sewer system, segregating sanitary and storm sewers into distinct systems. However, the functionality of these systems often needs to improve due to irregular interconnections, resulting in a mixed and malfunctioning system. Sewage collection is crucial for residential sanitation, but untreated collection significantly contributes to environmental degradation. Analyzing the simultaneous operation of both systems becomes vital for effective management. Using mathematical tools for precise and unified diagnosis and prognosis becomes imperative. However, municipal professionals and companies need more tools specifically designed to evaluate these systems in a unified way, mapping all the hydraulic connections observed in practice. This study proposes a unified simulation method for stormwater and sanitary sewer urban systems, addressing real-world scenarios and potential interferences. The primary goal is to develop a simulation method for both systems, considering system interconnections and urban layouts, involving hydrodynamic and water quality simulations. The practical application of this method, the Multilayer Hydrodynamic Simulation Method (MODCEL-MHUS), successfully identifies issues in urban water networks and suggests solutions, making it a valuable tool for urban water management and environmental engineering professionals.
许多国家和地区已经开始采用独立的下水道系统，将卫生下水道和雨水下水道分开为两个独立的系统。然而，由于不规则的连接，这些系统的功能往往需要改进，导致系统混合和故障。污水收集对于住宅卫生至关重要，但未经处理的污水收集会严重导致环境恶化。分析这两个系统的同时运行对于有效管理至关重要。使用数学工具进行精确和统一的诊断和预测变得至关重要。然而，市政专业人员和公司需要更多专门设计的工具，以便以统一的方式评估这些系统，映射实际中观察到的所有水力连接。本研究提出了一种用于雨水和卫生下水道城市系统的统一模拟方法，解决了实际场景和潜在干扰问题。主要目标是开发一种同时考虑系统连接和城市布局的两个系统的模拟方法，涉及水动力和水质模拟。该方法的实际应用，即多层水动力模拟方法（MODCEL-MHUS），成功地识别了城市水网络中的问题，并提出了解决方案，使其成为城市水管理和环境工程专业人员的宝贵工具。
