美国环境保护署和密歇根大学测试了先前开发的用于研究水分配系统中的变化的建模概念，包括现场采样程序来验证、校准和确定模型的准确性。这些模型在康涅狄格州中南部地区水资源管理局（SCCRWA）进行了测试，该局服务于康涅狄格州纽黑文。为SCCRWA的柴郡服务区开发了一个试点水力和水质模型。为了确定模型的准确性，进行了现场监测程序，以校准和验证模型。本文简要介绍了设计和进行现场监测研究所用的程序，以及该研究的一些显著结果。现场监测较好地反映了模型预测的总体趋势。

The US Environmental Protection Agency and the University of Michigan tested previously developed modeling concepts for studying changes in a water distribution system, including a field sampling program to verify, calibrate and determine the accuracy of the model. The models were tested in the South Central Connecticut Regional Water Authority (SCCRWA), serving New Haven, Connecticut. A pilot hydraulic and water quality model was developed for the SCCRWA's Cheshire service area. To determine the accuracy of the model, a field monitoring program was conducted to calibrate and validate the model. This paper briefly describes the procedures used to design and conduct the field monitoring study as well as some of the notable results of the study. The general trends predicted by the model were mirrored fairly well by the field monitoring.
