Hi,I am modeling a subcritical flow towards a waterfall. At my upstream boundary, I want to have normal flow conditions. Until now, I used a Dirichlet boundary condition with normal stage and discharge at a distance close to a backwater length upstream, but this is affecting the flow depth at the overfall because I am imposing discharge and depth at the inflow boundary when it should really be controlled by the drawdown effect of the waterfall. Is there another boundary condition that would be more appropriate for me to use? (I played around with Transmissive_n_momentum_zero_t_momentum_set_stage_boundary, and tried to use it with a constant stage at the inflow boundary, nut my domain dries out in a few time steps)Many thanks in advance for your help,- Mathieu Lapotre

Hi,

I am modeling a subcritical flow towards a waterfall. At my upstream
boundary, I want to have normal flow conditions. Until now, I used a
Dirichlet boundary condition with normal stage and discharge at a distance
close to a backwater length upstream, but this is affecting the flow depth
at the overfall because I am imposing discharge and depth at the inflow
boundary when it should really be controlled by the drawdown effect of the
waterfall.
Is there another boundary condition that would be more appropriate for me
to use? (I played around with
Transmissive_n_momentum_zero_t_momentum_set_stage_boundary, and tried to
use it with a constant stage at the inflow boundary, nut my domain dries
out in a few time steps)

Many thanks in advance for your help,

- Mathieu Lapotre
