Key Position of GIS in Hydro-Technologies and Hydrological Risks Assessment
Track: Water Distribution, Wastewater, and Stormwater
Author(s): Philippe Gourbesville
With an increased public awareness of flooding and flood-related issues, many municipalities and regulatory authorities are requiring a higher degree of accuracy in flood studies and modeling. In this background, runoff management is an essential questions specially for the construction of new public buildings, which must be preserved from flooding. To obtain a realistic estimation for the new infrastructures, a full 2D modeling can be used. The efficient modeling approach is based on a hydraulic model implemented in a GIS interface, which allows the production of high definition DEMs and video animations for the flood dynamic. This approach, applied in very sensitive urban areas, allows authorities to obtain a realistic description of the flooding processes.
