Abstract
The University of Georgia will complete
the National Hydrography Dataset for the State of
Georgia by the end of the 2003 calendar year. The next
stage in the maturation of Georgia’s water resources
database is the conversion to Arc Hydro – An ArcGIS
data model for water resources. This geodatabase
based capability enables a behavioral approach to data
modeling that enables a paradigm maturation beyond
the comprehensive integration needed for a hydrologic
information system to potentially enabling real-time
modeling in the GIS context. The full capabilities of
Arc Hydro are being realized using ArcGIS 8.3 with
geodatabase dynamic segmentation functions necessary
for stream networking. This implementation of Arc
Hydro represents the foundation for the eventual
construction of a comprehensive, integrated, real-time,
environmental modeling capability for the State of
Georgia.
