Hydrologic Fluxes and Flows

Digital Watershed(Atmospheric, surface and subsurface water)

We need to represent the physical environment

and water flowing through it

Created first for the Neuse basin

arc hydro geodatabase model for water resources
Customization of ArcGIS for water resources.

Public domain data model and toolset

Stores time series as well as geospatial data

Attach remote sensing and climate model files using links

Integrate data into a coherent space-time framework

conclusions
Conclusions
  • A good start has been made with HIS
  • Digital Hydrologic Library and Digital Watershed ideas are reasonably well formulated
  • Work on mass balances, fluxes and flows is developing
  • CUAHSI HIS Symposium in Austin, Tx, on March 7-9, 2005
