拉斯维加斯山谷水区（LVVWD）正在开发一个综合的 包括监控和数据采集（SCADA）系统的系统 水力和水质模型、地理信息系统（GIS）和其他 数据库系统。SCADA系统不断观察和收集实时数据 内部不同位置的系统水力、水质和运行的变化 供水系统。SCADA系统中收集的数据对于 模型校准和验证。该模型利用SCADA数据计算水力流量 以及运行调整、意外情况或假设情况下的水质结果 情节。该模型还使用GIS中的空间数据来更新模型设施。这个 GIS利用SCADA数据和模型输出，并绘制信息，作为可视化的辅助工具 系统增强、运营规划和决策支持。综合系统 使数据处理尽可能自动化，以便 节省了人力和时间。本文描述了这种整合的意义 并通过三个应用实例展示了它的价值。 包括2个参考文献、图表。

The Las Vegas Valley Water District (LVVWD) is developing an integrated system that includes a Supervisory Control and Data Acquisition (SCADA) system, a hydraulic and water quality model, a Geographic Information System (GIS), and other database systems. The SCADA system constantly observes and collects real-time changes in system hydraulics, water quality, and operations from various locations within the water distribution system. The data collected in the SCADA system is important for model calibration and validation. The model utilizes SCADA data to compute hydraulic and water quality results for operational adjustments, unexpected conditions, or what-if scenarios. The model also uses spatial data in GIS to update the model facilities. The GIS utilizes both SCADA data and model output, and plots information as a visual aid for system enhancement, operational planning, and decision support. The integrated system enables the data process to be automated to the maximum extent possible so that manpower and time are saved. This paper describes the significance of such integration and demonstrates its value with three example applications. Includes 2 references, figures.
