I am modelling a dam break using the MOHID Land and I can see the flooding using the "water column" inside the runoff hdf5 file.
But I want to keep the maximum value in each position, to plot as a map after the simulation.
How can I do ithis?
Is there a keyword to change and produce this output?
Thanks for the help!

Hello Jader,
In the RunOff module configuration you can set the option "Write flood hazard" to True. Then you run the simulation and 4 Grid Data files will be generated in the simulation results folder (..\res\RunX - where X is the ID of your simulation).
FloodPeriod.dat - period of time each grid cell was flooded (in seconds)MaxFloodRisk.dat - maximum flood risk for each grid cell (where risk is computed as "water column" x ("velocity modulus" + "risk coefficient") and risk coefficient is = 0.5MaxWaterColumn.dat - maximum water column each grid cell computed during the simulation VelocityAtMaxWaterColumn.dat - water velocity at maximum water column for each grid cell
You can load and display these files in the map window using the Grid Data button in the "MOHID specific layers" Map toolbar.
Kind regards,Luis
Do you have any paper or book to recommend about the "Max Flood Risk" formulation?
Thanks a lot Luis!!!
In fact, the MaxFloodRisk is not actually a risk, but more a hazard (or dangerousness). The formulation was developed within the framework of a flood mapping study for the Portuguese Environmental Agency. You can find more information here (in Portuguese, which will not be a problem for you :))
