Hi,

I've tried the equilibrium sediment disharge (according to my ICF) on the example canal_solid_discharge by changing the .cli files to :
4 5 5 0 0 0 0 5 0 0 0 X X
LIEBOR = 5 & EBOR = 0

Now I want to impose only X% of the equilibrium sediment discharge.
Which subroutines deals with equilibrium sediment discharge ? I'm a bit confused with conlit.f, disimp.f and bedload_solvs_fe.f .....

Best regardes,
P.N

I've made some tests to understand how and where solid discharges are exactly comptued. Instead of resolving my problem I encountered a new one.

I've modified canal_solid_discharge example to reproduce a flume without inflow solid discharge and wihtout available sediment on the bottom.It should look like a T2D run.

To avoid sediment transport, boundaries conditions files looks like
LIHBORLIQBORLIVBORQ2BORUBORVBORAUBORLIEBOR
45500004
It means constant constant sediment discharge equals to Q2BOR value 0.
In noerod.f, I set ZR=ZF and add in my .cas file
OPTION FOR THE TREATMENT OF NON ERODABLE BEDS = 2 (NUL SOLID DISCHARGE)
I should have 0 solid discharge in all my domain. This is confirmed by the listing.
But when I look to my result file (.slf) I see bed-load fluxes in all my domain according to my IFC (in my cas = 1).


Can someone knows why ?
