本文概述了配水系统中的水质建模。定义并讨论了五种一般类型的模型:水力模型、稳态水质模型和流量追踪模型、动态水质模型、优化模型和分析/显示模型。这些模型有许多应用:水质研究、校准和模型调查。作为一项相对较新的技术，其潜在影响尚未明确界定，但可能包括:监管流程、配电系统监控策略、法律诉讼、管理和运营、储存设施的设计和运营，以及健康影响；每种类型都有一些具体的含义。研究需要从更好地理解物理、化学和生物过程到开发技术转让。

This paper presents an overview of water quality modeling in a distribution system. Five general types of models are defined and discussed: hydraulic models, steady state water quality models and flow tracing models, dynamic water quality models, optimization models, and analysis/display models. These models have a number of applications: water quality studies, calibration, and model investigations. As a relatively new technology, the potential implications are not well defined, but may include: the regulatory process, distribution system monitoring strategies, legal proceedings, management and operation, design and operation of storage facilities, and health effects; some specific implications are given for each type. Research needs range from a better understanding of the physical, chemical, and biological processes to development of technology transfer.
