本文讨论了在西得克萨斯州科罗拉多河市政供水区（CRMWD）的大型区域供水系统中建模氯化物的挑战和决策过程。输水研究的目的有两个:开发CRMWD输水系统的校准水力模型，作为CRMWD员工未来使用的操作工具；评估可能的系统改进，以加强系统运行并满足未来用水需求。这项特定研究涉及的系统挑战非常广泛，不仅包括液压系统限制，还包括有限的供水、水质问题、新供水的整合、地表水与地下水的使用、水需求的增长、能源成本，以及即将解除的电力管制。这项研究的目的是检查这些约束，并评估系统修改和添加如何提高系统能力、灵活性和经济性。 包括表格、数字。

This paper discusses the challenges and decision process of modeling chlorides in a large regional water system in west Texas, the Colorado River Municipal Water District (CRMWD). The purpose of the water transmission study was twofold: to develop a calibrated hydraulic model of CRMWD's delivery system to act as an operational tool for future use by CRMWD's staff; and, to evaluate possible system improvements to enhance system operation and meet future water demands. The system challenges involved in this particular study were extensive, including not only hydraulic system constraints but also limited water supplies, water quality issues, integration of new water supplies, surface versus groundwater use, growth in water demands, energy costs, and the pending deregulation of electrical power. The purpose of the study was to examine these constraints and to evaluate how system modifications and additions could improve system capability, flexibility, and economy. Includes tables, figures.
