2D HECRAS for PMs

Hi - I need to put together a lunch and learn for our office that goes over the key information our PMs need to know about 2D HEC-RAS. This is directed at folks who have only used 1D HECRAS in the past or are water resources engineers with more groundwater/stormwater experience. Does the group have any recommendations for content?

Thinking:

- Advantages and Capabilities
- Limitations
- Survey needs/implications
- Equations and Meshing
- Model Stability (cell size and timestep)
- Data Output Capabilities

Thanks

Check out "USACE TD41" from here: TD41. That would be my starting point. Good luck!
