The HEC-RAS model you just computed should take approximately 5 minutes to run. In the meantime, you can begin preparing your briefing slide(s).
As described in Task 1, the briefing slide template can be found in the CWMS_Class\database\Reports folder. You will need to present both scenarios (with and without levee breach) to upper management, and you know from past flood events what types of information to include in your briefing slides.
Without Breach Scenario:
Inundation Map
Peak Stage Information (Date/Time)
Max Depth of Flooding within the Leveed Area of Interest (Pike Grain #4 Levee for this scenario)
With Breach Scenario:
Inundation Map
Peak Stage Information (Date/Time)
Max Depth of Flooding within the Leveed Area of Interest (Pike Grain #4 Levee for this scenario)
Time to Reach Maximum Depth (after breach initiates)
Breach Data
Max Width, Formation Time
Once the HEC-RAS model compute is complete, you can determine the With Breach Scenario information by examining the results using HEC-RAS Mapper. You can now finish developing the slides and prepare for the meeting with upper management.
This flood scenario was driven by backwater on the Mississippi River and not by releases from the project upstream (Clarence Cannon Dam). If the flooding scenario was instead driven by high releases from the dam upstream, what type of information would you want to include on the briefing slides?
You should probably include information regarding the peak inflow to the reservoir, peak outflow from the reservoir, and any operational decisions that lead to the final forecast.
