I have an 2D hydrodynamic model in a approx. 10km² catchment and one rain event that goes one hour with measurements in a 5min interval. The reccurance interval for an event like that is close to 50years.
When I run my simulation software I get the flood heights for every m² in my catchment for every 30min. My question is, how do I validate my result? I guess, ideally I take the flood heights for 10 other rain events with the same intensity and duration and see if it fits my results. But I don't have these information.
what could be approaches to validate my model?
