open TELEMAC-MASCARET The mathematically superior suite of solvers

Good Afternoon

it is possible to enter the solid discharge as value to the opentelemac with sisiphe, If possible, how can I do it?

Please help, me

Hello,

Indeed, it's possible.
Solid discharges is one of the boundary conditions you can set with a boundary conditions file for Sisyphe.
Take a look at inflow boundary conditions in Sisyphe user manual for further details.

I hope this helps.

Best Regards,

Good morning

I was doing some tests entering a solid flow in the entrance of a trapezoidal channel, but when performing the simulation, sedimentation begins but it does not progress, someone could help me to understand what happens.


I'm attaching my files

How wide is your channel. The specified discharge is 56m3/s and the depth is 9m. This means for a 100m wide channel you will have 0.06m/s of flow velocity.

Hi,

Hi, I have an approximately rectangular section channel with width at the base of 4,572. And the velocity is 1.1 m/s ansd is subcritical flow.

I attached image.

I have reviewed the hydrodynamic model, I do not know if there is any problem with the entry of information in the sediment model

I think the following is happening:
You have a 'more or less uniform flow in the channel. The bed is mobile and therefore the bedload transport is constant along the channel, giving no change anywhere. However, at the entrance you are prescribing a much higher discharge than is realistic for these flow conditions and the material accumulates at the entrance.

I suspect you are intending to prescribe a solid discharge in kg/s, whereas the model interprets it as a discharge in m3/s.

Currently I am comparing this channel with a model made in hec-ras, in the model hec-ras (one-dimensional) enter 3000 ton / day. To this value I have transformed it into volume and I divided it between the width of my channel. I have recalculated and the value for each cell I get 0.0017 m2 / s. If I add a high solid flow, the tendency is to accumulate in the income ?, that occur internally in the program or should I add the exact value of income?
