USGS Flood Inundation Mapping: Plans for a Collaborative Future

Transcription

1 USGS Flood Inundation Mapping: Plans for a Collaborative Future Marie C. Peppler USGS FIM Program Liaison U.S. Department of the Interior U.S. Geological Survey

2 USGS and NWS Data Networks Over 9,000 USGS Gages reporting current stream conditions in NWIS Over 4,000 NWS Flood Forecast/Warning locations in AHPS

3 Flood Inundation Maps translate a hydrograph into operational maps that communicate risk and consequences

4 FIM becomes a tool for flood.. Preparedness What-if scenarios Response Tied to gage & forecast data Recovery Damage assessment Mitigation & planning Flood risk analyses Environmental & ecological assessments

5 Environmental Aspects Ecological studies of floodplains E.g. frequency of inundation Riparian wetland applications 7-day inundation areas for Wetland Reserve Program Hazardous substance spills MI Kalamazoo River Oil Spill

6 Creation of Inundation Map Libraries Gage/HWM Calibrated Hydraulic Model High Quality Elevation Model Series of sequential maps showing probable areas of inundation from bankfull to record stages

7 USGS FIM Mapper more than just maps + + Flood Library USGS Real-time streamgage NWS Flood Forecast

25 USGS FIM Toolbox Available to partners Key Contacts Program Development Flood Documentation Flood Libraries Other FIM research areas

26 The IWRSS FIM Requirements Team USACE, NWS and USGS (FEMA) are working together to form common requirements for FIM Includes basic methods, QA/QC and documentation standards, metadata and database Structure for an interagency peer review process Mechanisms for growth and flexibility Goal: to have one Map

27 We need your help. ±3000 possible community locations (DEM?) Even if IWRSS was fully funded we cannot do it New Technical Assistance Agreement process designed to collaborate closely with the Private Sector to develop maps for all USGS gages/ NWS forecast points
