As we get the bed load rate and suspended load rate in the unit of m2/s from Sisyphe, plz let me know the process to calculate total volume of sediment deposited (m3/s)in the simulated time.
I will be very grateful.

Hi
you could have the bottom evolution and by integration the volume of sediment...

Hi

Evolution could be an output variable of Sisyphe.
You could also compute this variable by difference between the last and the initial time step.
Then you could compute the volume of Evolution

This is well explained in the BK manual at chapter 1.6.4.4 page 88.

Thank you very much for your quick reply.
I got the value of evolution (z).

I have uniform gridded mesh.

so the volume of sedimnet = delta x * delta y * sum of (z)

am I right? or let me know the other process to formulate volume using the value of evolution (z).

Thanking you

The volume is automatically computed by BK!
You don't have to take care about the formula!
