Flood extent example for a small lagoon

I’d like to get some help with a EFDC Explorer simulation. I want to simulate a flood extent for a small lagoon, considering different regimes of rain. There is a tutorial or example that I can use to set up my model for this type of simulation? What are the initial data that I need?

Hi Tinh, thanks for your reply.

I already have the atmospheric file correctly configured (see the snapshot). I also have a withdrawal boundary condition (Data series_Flow Snapshot) and I was expecting to see a reduction in the water extents after the simulation, but I cannot see anything. Where might be the problem? or how I can display this situation? Attached files
