2. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Red River Flood of the Century 10 years later 4 th International Symposium on Flood Defence May 6, 2008 Dan Luna, NOAA/NWS Accomplishments – Improvements

3. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Recommendations from the IJC Report after the ’97 Flood Implement Advance Hydrologic Prediction Services (AHPS). Improve hydrometeorologic data networks. Improve communications among forecasters with the public. Data supporting the operation of the hydraulic models and model outputs should be made widely available. Accomplishments – Improvements

4. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Specifically Implemented AHPS and new modeling. 1999 – FLDWAV implemented. 2002 – MIKE-11 implemented as a planning and potential forecasting tool along with a gis-based user tool. Accomplishments – Improvements

5. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Manitoba North Dakota Morris Grand Forks Winnipeg MIKE-11 model model Selkirk PTH #4 bridge Water levels calculated at 935 points. Flowcalculated at 525 points Accomplishments – Improvements

6. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Specifically Implemented AHPS and new modeling. 1999 – FLDWAV implemented. 2002 – MIKE-11 implemented as a planning and potential forecasting tool along with a gis-based user tool. 2005 - Existing FLDWAV model was updated by adding 161 cross-sections. Total – 554. Accomplishments – Improvements

7. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Background LIDAR Dark blue - Red River Light blue - secondary channel Green – cross- sections Yellow with Red outline – City of Fargo Accomplishments – Improvements

8. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Specifically Implemented AHPS and new modeling. 1999 – FLDWAV implemented. 2002 – MIKE-11 implemented as a planning and potential forecasting tool along gis-based tools. 2005 - Existing FLDWAV model was updated by adding 161 cross-sections. Total – 554. 2006 Lumped model was re-calibrated. Accomplishments – Improvements

9. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship What Did We Do? Implemented AHPS and new modeling. Improved hydrometeorologic data networks. Accomplishments – Improvements

10. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Stations that report daily Accomplishments – Improvements

11. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship LEGEND Accomplishments – Improvements

12. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship What Did We Do? Implemented AHPS and new modeling. Improved hydrometeorologic data networks. Drastically improved communications among forecasters with the public and emergency management and improved Municipal, Provincial and Local Response. Accomplishments – Improvements

13. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Communication, Coordination, and Collaboration are a must Flows are sent to Manitoba as well as our other Federal water partners. Coordination takes place continually during significant floods. Collaboration takes place during high impact events (New for 2006). Accomplishments – Improvements

14. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Successes in Spring 2006 Started communicating our concerns as early as 1/9/06 and followed that up in early February with updated information. Really stressed our concerns. Continued this approach as time went on and expanded the e-mail list to those appropriate. Asked the “local flood experts” their opinions in terms of what they thought the possibilities were before forecast issuance. Accomplishments – Improvements

15. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship Successes Spring 2006 ‘cont Conveyed information daily via conference calls and state EOCs. With IWI involvement we held 2 Press Conferences, before and during flood. Resulting communication was one clear voice. Resulting coordination and collaboration was one forecast with credibility. Accomplishments – Improvements

16. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship What’s Next? Recommendations FLDWAV model needs to be expanded. Cross-sections extended and/or added. Area included within the model, Sheyenne River upstream to Kindred. Assumes additional LIDAR data will be available Accomplishments – Improvements

17. NOAA/NWS River Forecast Center Chanhassen, MN Manitoba Water Stewardship What’s Next? Recommendations Need to further improve hydrometeorological networks – additional snow water equivalent, frost, and rainfall data essential to better forecasting. Need to have a better grass roots effort in terms of providing this critical data to the river forecast centres in Minnesota and Winnipeg when we have the potential for significant flooding.
