Hi, all of telemac user.
First of all, I got a lot of knoledge about telemac from here.
so I want to say to you thanks.
and I know that actually this topic is not new one.
but I coudn't find enough information. so I write this question here.

My question is about time-varying solid discharge.
I can apply constant sediment discharge.(by using keyword PRESCRIBED SOLID DISCHAGE in fudaa, and also Q2BOR in boundary condition file.)
and now I'm working on conlit.f to use time varying solid discharge.
In conlit.f, there is code like this

IF(LICBOR%I(K).EQ.KENT.AND.
& SIS_FILES(SISLIQ)%NAME(1:1).NE.' ') THEN
IF(IFRLIQ.GT.0) THEN
DO I=1,NSICLA
CBOR%ADR(I)%P%R(K)=CGL(IFRLIQ,AT)/XMVS
ENDDO
ENDIF
ENDIF

I think I should use this code, because there is AT(TEMPS).
but it seems that it is connected only to 'concentration',
not related with sediment discharge(prescribed discharge).

<<Qeustions>>
1) Should I copy this code to where prescribed discharge is?
2) is it right that 'SIS_FILES(SISLIQ)%NAME(1:1)' is liquid boundary file of sisyphe?
3) Finally, is it exactly possible to apply time-varying solid discharge by using conlit.f?

Thanks too much for your attention.
Sincerely.

Dear Noah,
thanks for your post. Effectively, you can use the soubroutine conlit.f to impose a time-varying sediment inflow into the domain.
You can use the variable QBOR to impose the corresponding values.
Your implementation must be done in the part of the code before the comment line:
! LICBOR : BOUNDARY CONDITION FOR SEDIMENT CONCENTRATION

I hope it helps,

all the best,

Pablo

Dear Pablo.
Thank you very much for your attention.
and I think now I can apply time varying solid discharge.
I attached my 'conlit.f' below.
but I wonder this is right,
Becuase you said the code location.

Could you check my fortran file?
All the best.
