Solved it. Issue was that lateral structures connecting to 2D tributaries need a higher Cd for the weir.

If anyone else runs on this problem: Use ~0.5 Cd for lateral structures connecting to floodplains, and between 2-5 when connecting to tributaries (calibrate accordingly to minimize percent error in mass balance).

Hope this helps.

Thanks!

– 5 sec time step
– lateral structures set to weir (0.5 Cd)
– Diffusion wave

I don’t think any of these setting will help improve the percent error though.

Update: Decreasing the number of XSs significantly reduces the error, but still high (~19%).
