FAQ/ Cross-section of a river channel with a riverbed higher than the height of the left and right banks¶
In a certain river channel cross-section, there are places where part of the river channel is higher than the height of the top of the left and right banks. Even in this case, is the exchange of water levels between the floodplain and the river channel calculated in relation to the ground height of the floodplain, the height of the left bank and the top of the right bank set in the river channel (cross-sectional data), and the river water level?
response¶
Yes. It works that way.
Some riverbeds that are higher than the height of the left and right banks do not serve as connection points with the floodplain. The connection relationship between the floodplain and the river channel is determined by the user-specified left and right bank tops for river channels, and by the user-specified crossing position and river line for floodplains. It does not depend on the shape of the river channel.
