  1. Indiana Silver Jackets Real-time Inundation Mapping Pilot Project Scott Morlock USGS Indiana Water Science Center October, 2009

  2. Silver Jackets Vision A dynamic flood mapping application, based on real-time and forecast hydrologic data, for EVERY flood-prone community

  3. Inundation Mapping Pilot Project • IN Silver Jackets Pilot Project • 11-miles, White River, Indianapolis • Tied to USGS streamgage & NWS flood forecast point

  4. The Partnership Funding: • City of Indianapolis • Indianapolis Museum of Art • IN DHS • USGS • The Polis Center In-kind: • NWS • IDNR • IU Grid Lab • All Silver Jackets Partners

  5. The Project Components: • Static flood maps library • HAZUS detailed analysis • Real-time dynamic application

  6. Approach • Develop GIS static map library • Perform Level 2 Hazus analysis • Build dynamic application based on static map effort • Partners use & test dynamic application • Implement static maps publically through NWS AHPS

  7. Progress • Static map library delivered to partners • Polis completed HAZUS analysis & report • Dynamic RT application rolled out in June • Working with NWS on AHPS delivery

  8. Static Library Mapping Process • Gathered DEMs, channel geometry, high-water mark, streamgage historic data. • Built calibrated hydraulic model – USGS FastMech • Made multiple model runs for increasing streamflow/stage • Produced a map GIS grid for each stage at a preset interval – e.g. every foot

  9. FastMech – What and Why WHAT • USGS 2-D hydraulic model • GIS front end (MDSWIMS) WHY • Speed • Stability • “Auto-adjusting” • Outputs flood grids

  10. Static map library • Maps in increments of 1 foot from bankfull to >21 feet • Delivered to partners through • GIS server • GIS raster files • PDF files • Working with NWS on AHPS delivery • QA/QC & metadata

  11. HAZUS Analysis • Polis Center • HAZUS MR-3 Level 2 Analysis – 15 min. • Imported flood grid • Imported inventory – IMAGIS • # structures, structure damage, structure count by category

  12. SOA – Service Oriented Architecture Allows different applications to exchange data with one another. Products/services based on interoperability of independent & distributed applications.

  13. Some points • RT application is state-of-the-art – and experimental! • IN approach • Get RT infrastructure built and tested • Build static map libraries served through AHPS • Implement static models in RT application later • A platform to build on – more complexity, trib inputs, breach modeling • Highly expandable, ideally suited for partnering – everyone can have a part

  14. Potential partner components • NWS – flood forecasting, tech guidance, QA/QC • USGS – streamgaging, channel surveying, H&H • FEMA – HAZUS-MH, RiskMap • USACE – hydraulic modelling, reservoir ops • Private sector – new hydraulic models • State and local partners – flood response plans • Universities – research, social science

  15. Issues • Sensitivity • DEM data • Models • Channel data • Maintenance • Channel changes • Levees, etc • Hazard communication & public awareness Prof. Venkatesh Merwade, Purdue University
