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

5. Pre Conference Seminar 5 Arc Hydro: GIS for Water Resources Arc HydroArc 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 Published in 2002, now in revision for Arc Hydro II

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

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

8. Pre Conference Seminar8 What Makes Arc Hydro different? 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 ArcGIS: All features are labeled with a unique ObjectID within a feature layer Arc Hydro is a unique “flavor” or style of doing GIS

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

10. Pre Conference Seminar 10 Challenges in developing Arc Hydro ArcGIS is a very successful static, 2D or 2.5D systemArcGIS is a very successful static, 2D or 2.5D system For surface water resources we needFor 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 needFor groundwater resources we need – 3D representation of boreholes and hydrogeologic units – Integration with groundwater models, especially Modflow, which has become the ArcInfo of groundwater
