Integrating GIS with Water and Wastewater Hydraulic Models
Defining Issue: Developing automated applications to transfer information between a water/wastewater facility management GIS database in ArcInfo to specialized water and wastewater hydraulic modeling applications to support master planning and design operations. GIS Solution: In the past few years, advances in infrastructure management technology have been occurring at an accelerated pace. The development of database management systems (DBMS) and geographic information systems (GIS) is greatly expanding the potential to integrate independent utility operations, computer information systems, and applications. This presentation describes the integration of an existing infrastructure management system and a newly developed geographic information system with specialized hydraulic modeling applications for the Broward County, Florida, Office of Environmental Services (BC-OES). Methodology: Primary objectives of the integration effort include utilization of the BC-OES' existing Oracle-based infrastructure
management system database as a centralized database, development of an ArcInfo and ArcView-based GIS to query and display infrastructure data and to generate map products, and development of ArcView-based applications to automatically prepare water and wastewater hydraulic models. The presentation describes the methodology applied to integrate the infrastructure management system, GIS, and network models, with a focus on the applications developed to prepare hydraulic model inputs. A major focus of the presentation is the methodology applied to resolve conflicting representations of water/wastewater network facilities between the infrastructure management database, GIS, and hydraulic models. A secondary focus is the organizational and operational changes made to support the integrated system. The presentation should prove useful to any water/wastewater utility planning to integrate GIS with hydraulic and water quality modeling and with master planning efforts. Software: The application to download
GIS data to the hydraulic models was developed using ArcView, Avenue, and Visual dBASE. Additional programs were written in ArcInfo, AML, INFO, and Oracle SQL to ensure that data are properly synchronized between the GIS database and the Oracle-based infrastructure management database. The primary GIS platform is ArcInfo. Data access is achieved through numerous ArcView licenses on network client PCs.
