Floodplain
Dear Chris,
In our model the valley through which the river flows widens up at the most downstream section. So we used floodplains to define the channel geometry at this section. In the outputs we get higher flow depths in the cross sections with floodplains than in the cross sections upstream with no floodplains.
Why? We suppose, that the water downstream should dispread over the floodplain and as a consequence the flow depht should be not so high.
Yours sincerely
Karin & Bethi
