How is momentum treated with culverts?

Hi,

I am using modified culverts to represent the tidal turbines (discharge prescribed with a "Hill chart") in a tidal lagoon. The lagoon is enclosed with thin walls and the intake and outlet of a culvert are in the adjacent cells, one on each side of a thin dam. I am worried about how momentum is assigned at the discharge from the culvert.

In the manual it says that for discharges: "The momentum released to the flow due to a discharge is distributed over the velocity points that bound the quadrant in which the discharge is released." But my understanding is that only the Type=momentum discharge has the functionality where user can specify the direction and magnitude of out-coming velocity.

So how is the momentum then treated with culverts? It doesn't say anywhere in the manual. All I could find is that culverts are considered a special form of in-out discharge

Does anyone know where in the source code the discharges are added to the momentum terms, so I could potentially prescribe the direction manually? I did some investigation myself, however the source code can be quit hard to follow.

Any help will be much appreciated emoticon

Regards, Nejc

I don't think that I can help you with that because I don't have any knowledge about this. I was reading some Important content for my essay work at a cheap assignment writing service and that's why I had no time for any other work. Do you know any service which can help me with my writing work?

Box culvert tidak membutuhkan galian tanah yang dalam, sehingga hal tersebut cukup memudahkan kontraktor. Kemudahan dan kecepatan pemasangan membuat pemakaian box culvert sebagai saluran air semakin diminati. Tata cara memasang box culvert adalah sebagai berikut :

The American Society of Testing and Materials (ASTM) Specification C1577, entitled Precast walmart paystub Reinforced Concrete Monolithic Box Sections for Culverts, Storm Drains, and Sewers Designed According to AASHTO LRFD, can be used to design and detail these systems.
