  4. Linking GIS and Water Resources Water Resources GIS Pre Conference Seminar

  5. Arc Hydro An ArcGIS data model for water resources Arc Hydro toolset for implementation Framework for linking hydrologic simulation models Arc Hydro: GIS for Water Resources Published in 2002, now in revision for Arc Hydro II The Arc Hydro data model and application tools are in the public domain Pre Conference Seminar

  6. Arc Hydro —Hydrography The blue lines on maps Pre Conference Seminar

  7. Arc Hydro —Hydrology The movement of water through the hydrologic system Pre Conference Seminar

  8. 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 …. IDRelationships link neighboring features and help to trace water movement Arc Hydro is a unique “flavor” or style of doing GIS Pre Conference Seminar

  9. What Makes Arc Hydro different? Arc Hydro connects space and time: HydroFeatures are linked to time series Flow HydroID Time FeatureID Time Series HydroFeatures Pre Conference Seminar

  10. 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 Pre Conference Seminar
