Arc Hydro GIS for Water Resources
Published in 2002, now in revision for Arc Hydro
II

• Arc Hydro
• An ArcGIS data model for water resources
• Arc Hydro toolset for implementation
• Framework for linking hydrologic simulation
  models

The Arc Hydro data model and application tools
are in the public domain

What Makes Arc Hydro different?
ArcGIS All features are labeled with a unique
ObjectID within a feature layer
Arc Hydro All features are labeled with a unique
HydroID across the geodatabase
HydroID to . ID Relationships link neighboring
features and help to trace water movement
Arc Hydro is a unique flavor or style of doing
GIS

Challenges in developing Arc Hydro

• ArcGIS is a very successful static, 2D or 2.5D
  system
• For surface water resources we need
• Close connection between raster terrain and
  vector stream data
• Linkage to time varying water data observations
  stored at gages
• Access to precipitation and evaporation data
  fields
• For groundwater resources we need
• 3D representation of boreholes and hydrogeologic
  units
• Integration with groundwater models, especially
  Modflow, which has become the ArcInfo of
  groundwater
