Application of a Geographic Information System to Estuarine Hydrodynamic Modeling

by Jerad D. Bales,
Douglas J. Newcomb,



Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract:

A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display, analysis of model results, and linkage of hydrodynamic information with other types of spatial data. The geographic information system was used to develop a computational grid, consisting of 200-meter square cells, for Albemarle Sound. Any combination of seabed elevation, water-surface elevation, salinity, velocity-magnitude contours, and velocity vectors can be produced by the geographic information system. Automated selection and display of regions having designated combinations of hydrodynamic characteristics is possible using the analytical capabilities of the geographic information system.
