Silver Jackets Vision

A dynamic flood mapping application, based on real-time and forecast hydrologic data,

for EVERY flood-prone community

Inundation Mapping Pilot Project

IN Silver Jackets Pilot Project

11-miles, White River, Indianapolis

Tied to USGS streamgage & NWS flood forecast point

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

The ProjectComponents:

1.Static flood maps library

2.HAZUS detailed analysis

3.Real-time dynamic application

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

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

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

Static Library Mapping Process

FastMech – What and Why

WHAT USGS 2-D hydraulic model GIS front end (MDSWIMS)

WHY Speed Stability “Auto-adjusting” Outputs flood grids

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

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

SOA – Service Oriented Architecture

Allows different applications to exchange data with one another.

Products/services based on interoperability of independent & distributed applications.

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

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

Issues

Sensitivity DEM data Models Channel data

Maintenance Channel changes Levees, etc

Hazard communication & public awareness
