FAQ/ Closing the downstream end of a river

Does the water that reaches the downstream end of the river model overflow into the flood model?

If so, I thought it would be necessary [Sea]to mesh the flood model near the downstream end of the river [Open] to or .

response

In the river model, the water that reaches the downstream end of the river disappears. To be precise, it is displayed in a space that is not subject to analysis.
Therefore, you do not need to edit the mesh of the flood model.

However, if the River property [Close downstream end] is set to true, the water that reaches the downstream end will overflow into the floodplain.

For more information, please refer to Technical Reference/River Model/Closing the Downstream End.
