Floodplain maps (White Oak Bayou, Houston)

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

Water Quality

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

Nueces Bay Zinc in Oyster Tissue TMDL Project Imane Mrini Center for Research in Water Resources The University of Texas at Austin

Mean = 37µg/L Zinc loads to Nueces Bay Outflow Atmospheric deposition W at = kg/d NPS watershed loadings Q wsh = 1.83 m 3 /s W wsh = 3.69 kg/d Lake Corpus Christi load Q NR = 2.47 m 3 /s W NR = 4.27 kg/d Nueces Bay Permitted discharges Q pd = m 3 /s W pd = 0.71 kg/d CP&L plant W CP&L = kg/d Inner Harbor Average Conc. ( ) = 37µg/L Q = flow of water W = 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

Nexrad Map to Flood Map in Arc 9 Model Builder FLO ODP LAIN MAP Flood map as output Model for flood flow Model for flood depth HMS Nexrad rainfall map as input

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.
