Arc Hydro: GIS for Water Resources
• 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 andapplication tools are in the publicdomain

FEMA Map Modernization Program
• FEMA is redoing floodplain maps for whole nation over next 5 years, county by county
• Spend $1.5 billion on this• Store data and models in server farm in
Cary, NC for whole country • How to relate all this to Arc Hydro?• How to quantify the error in floodplain
boundaries?Joint project with Dr Hodges

Location of Impaired Waters
Waters are “impaired” when their quality is inadequate for “designated uses”,e.g. fishing and swimming

Q = flow of waterW = load of zinc
Bacterial TMDL for Copano Bay
• DNA studies to “type” the sources of bacteria in water have been done (animals,humans, birds, etc)
• What is the loading of bacteria to the bay from these sources?
• How can loading be reduced to make bacterial concentrations acceptable?
• TMDL = Total Maximum Daily Load
Joint project with Dr Kirisits

Interface Data Model for HSPF
• Previous work has focused on flooding with HEC-RAS and HEC-HMS models
• Moving now to integrate water quality modeling• HSPF – Hydrologic Simulation Program Fortran• Widely used simulation model for water quality
modeling• How to connect this to GIS requires detailed
design of the interface and developing computer tools to achieve that integration.
