Hi all, I’m trying to create a model that all the culverts is working during initial condition, but then when the dam breaks, all/part of the culverts are blocked. I couldn’t delete the culvert for the dam break situation, since the geometric data for the base condition and the break condition need to be the same. Is there anyway I can perform this? Or can I simply know the flows going through the culvert in a 2D simulation? Thank you!
