I would like to find out how 1 would measure or determine the LOB and ROB in a river channel that has a lot of bends . It’s easy measuring the LOB and ROB in a fairly straight river channel but it gets tricky when the river channel has a lot of bends .
It all depends on what flow you are modeling. Is the flow going to over top the banks of the river and act as if the channel doesn’t exist (common at very high flows) or is it going to follow the meanders of the river?
