概述了改善和扩建配水设施的水系统建模方法。弗吉尼亚州夏洛茨维尔的网络建模帮助优化了几个增压泵站的运行计划，以提高效率并降低电力成本。其他用途包括评估新的输电主要需求，审查水系统的弱点或不足，以及确定改进和加固的优先事项。在阿拉巴马州的迪凯特，一个水力网络模型主要与正在进行的配水干线改进、确定具有成本效益的干线尺寸以及干线安装和更换有关。阿拉巴马州奥佩利卡市的市政供水系统采用水力网络模拟来改善火灾状况- 流量能力、拟建高架储罐的容量模拟，以及新供水水源的开发。包括7个参考文献、图表。

An overview of the methods of modeling water systems to improve and expand distribution facilities is presented. Network modeling in Charlottesville, Virginia helped optimize the operating schedule of several booster pumping stations to improve efficiency and reduce power costs. Other uses included evaluation of new transmission main needs, review of water system weaknesses or deficiencies, and establishment of priorities from improvements and reinforcements. In Decatur, Alabama, a hydraulic network model has been primarily associated with ongoing distribution main improvements, determination of cost-effective main sizes, and main installation and replacement. The municipal water system in Opelika, Alabama employs hydraulic network simulations for improvement of fire-flow capabilities, capacity simulation for a proposed elevated storage tank, and development of new water supply sources.
