Dear mohammad

What actually you want to add into F3D?

Regards.

Hi dear Ghirghidov
i have a question
in initial, you input 991 for sediment concentration
how you calculate it?
Many thanks and best regards,
Hosain

Dear Hosai.

I used it from the example. IMHO you could use 100 or 1000 does not matter.

Dear obama549.

The scouring rate depends on sediment tipe and discharge ond many other things.

Hi bojiezhang,

I have same problem too with F3D 9.2, think you can share the problem. i modeling scour around rectangular pile group.. but all sediment going up by wave.. i have limited the depth of sediment but unsatisfied result :(
