本文作者将一个供水管网建模程序和一个地理信息系统（GIS）连接起来，以便在这两个系统之间进行数据传输。该方法是在马萨诸塞州水资源管理局（MWRA）的GIS实施项目过程中开发的。实施过程包括七个步骤:在GIS中绘制配电系统地图；将智能添加到GIS文件中；在GIS中编写菜单驱动程序，将描述性文件作为网络模型的输入； 基于GIS生成的信息，建立供水管网的模型（在网络建模程序中）；在网络模型内进行水力模拟；写入包含网络模型预测值的输出文件；以及为现有的GIS数据库添加智能。说明了使用这种方法的优点。MWRA现在能够根据GIS数据库中包含的大量环境和社会经济数据，分析配电系统模型提供的复杂预测水量和需求，并利用GIS强大的分析能力。

This authors linked a water distribution network modeling program and a geographic information system (GIS) to allow data transfer between the two systems. The methodology was developed during the course of a GIS implementation project for the Massachusetts Water Resources Authority (MWRA). Implementation involved seven steps: building a map of the distribution system in the GIS; adding intelligence to the GIS file; writing a menu-driven program within the GIS that will write out the descriptive files as input to the network model; building a model (within the network modeling program) of the water distribution network based on the GIS-generated information; performing the hydraulic simulations within the network model; writing an output file that contains predicted values from the network model; and adding intelligence to the existing GIS database. Advantages of using this methodology are explained. The MWRA is now able to analyze sophisticated predicted water flows and demands provided by the distribution system model, in relation to the extensive environmental and socioeconomic data contained in the GIS database and to take advantage of the powerful analytical capabilities of the GIS.
