tailieunhanh - GIS Applications for Water, Wastewater, and Stormwater Systems - Chapter 12

GIS tiết kiệm thời gian và tiền bạc trong việc phát triển mô hình hệ thống nước phân phối thủy lực để mô phỏng dòng chảy và áp lực trong hệ thống. GIS cũng có thể giúp trong việc trình bày các kết quả mô hình để các khán giả không có kỹ thuật. | CHAPTER 12 Water Models GIS saves time and money in developing water distribution system hydraulic models for simulating flows and pressures in the system. GIS also helps in presenting the model results to non-technical audiences. EPANET and ArcView GIS integration. Copyright 2005 by Taylor Francis LEARNING OBJECTIVE The learning objective of this chapter is to understand how GIS can be applied in developing water distribution system hydraulic models and presenting the results of the hydraulic models. MAJOR TOPICS Development of hydraulic models Software examples EPANET model Network simplification skeletonization Estimation of node demands Estimation of node elevations Delineation of pressure zones Mapping the model output results GIS application examples and case studies LIST OF CHAPTER ACRONYMS AM FM GIS Automated Mapping Facilities Management Geographic Information System CIS Customer Information System COM Component Object Model COTS Commercial Off-the-Shelf DEM Digital Elevation Model DHI Danish Hydraulic Institute DLL Dynamic Link Library DRG Digital Raster Graphic GEMS Geographic Engineering Modeling Systems MMS Maintenance Management System ODBC Open Database Connectivity PRV Pressure Regulating Valve SCADA Supervisory Control and Data Acquisition TIF Tag Image File CITY OF GERMANTOWN S WATER MODEL Application GIS software Other software GIS layers Hardware Study area Organization Water distribution system mapping and modeling ArcGIS ArcGIS Water Utilities Data Model formerly ArcFM Water Data Model and MapObjects WaterCAD Digital orthophotos pipes hydrants valves manholes pumps meters fittings sampling stations and monitoring wells Two Dell Precision 220 computers City of Germantown Tennessee City of Germantown Tennessee The City of Germantown Tennessee water distribution system serves 40 000 people through 12 000 installations in a mi2 area.
