Utilization of GIS Software to Develop As-Built Terrains for Hydraulic Modeling July 2016 Technical Memorandum No. 86-68260-16-01 Utilization of GIS Software to Develop As-Built Terrains for Hydraulic Modeling Manuals and Standards Project ID: G6187 U.S. Department of the Interior Bureau of Reclamation Technical Service Center A methodology was developed by coupling GIS to a hydraulic calculation model (EPANET). The results showed that it is possible to obtain an alphanumeric description of the pipes, tanks, and all the accessories constituting the network. Design irregularities in the Tlemcen urban cluster's network were identified. Major research efforts toward the integration of GIS with hydrological modeling did not take place until the late 1980s, as a part of the GIS community's efforts to improve the analytical capabilities of GIS (Fotheringham & Rogerson, 1994; Goodchild, Haining, & Wise, 1992) and hydrologists' new demand for accurate digital representations of the terrain (Clark, 1998; Singh & Fiorentino, 1996).

In: Shekhar, S., Xiong, H. (eds) Encyclopedia of GIS. The integration of hydrology and GIS is therefore quite natural. The integration involves three major components: (1) spatial data construction, (2) integration of spatial model layers, and (3) GIS and model interface. GIS can assist in design, calibration, modification and comparison of models. The opportunity to apply the MIKE 11 hydrodynamic modeling package in this research was made possible by the Danish Hydraulic Institute and their provisions for the application of their modeling tools in academic research. In addition their international staff provided invaluable support and assistance throughout the course of this project.

Distribution-system models are becoming increasingly complex and are being used more regularly for various applications.
