Smart code to remove the clear water/tailings reservoir

Change Initial water elevation to Water elevation

I'm sorry for the bad audio, I was using the wrong mic.

That seems good to me. I think it will be effective.

@rpachaly

The R lines are going to need some tweaking. I've found recently that sometimes you do need a clear water reservoir even if you are modeling a tailings breach because you are setting up a downstream reservoir.

[FLO-2DKaren]

I also think there could be a time when you'd use two different reservoirs. One clear and one with tailings.

[rpachaly]

You can do this on the two-phase. Just don't set the tailings and it works

[FLO-2DNoemi]

Let me make sure I understand correctly, you should set up the R lines as follow:

R 5232 1734.02 0.250 Tailings R 5232 0.00 0.250 Clear water

I made a mistake, I think it should be as follows:

RESCHAR = ‘R’ IRESGRID(II) RESERVOIREL(II) TAILINGSELEV(II) RESERVOIRN(II)

R 5232 1734.02 1744.02 0.250 Tailings R 5232 1734.02 0.00 0.250 Clear water

I will review the FLOPRO code to double check this is ok, and understand how the TAILINGSELEV(II)= 0 is taken into account in the two phase flow.

Clear water is like this R 5232 1734.02 0.250

[rpachaly]

To create a water reservoir and a tailings reservoir using the two-phase:

Water -> R 20990 955.00 0.00 0.25
Tailings -> R 25835 0.00 936.00 0.25

Did a quick test here. The top reservoir is only water and the bottom reservoir is only tailings.

[FLO-2DKaren]

OK I see what you mean. I wasn't testing it with two phase. I was testing it with mudflow only.

[rpachaly]

I could not make it to work with only mudflow.

[rpachaly]

From my previous testing.

1. ONLY INFLOW.DAT

MUD and ISED = 0 Runs fine R 26006 936.00 0.25

MUD = 1 and ISED = 0 Runs fine and prints out CVFPMAX.OUT R 26006 936.00 0.25

MUD = 0 and ISED = 1 Runs fine and prints out SEDFP.OUT R 26006 936.00 0.25

MUD = 2 and ISED =0 Runs clear water and two-phase together R 20656 980.00 0.00 0.25
R 26006 937.00 936.00 0.25

2. ONLY TAILINGS.DAT

MUD = 1 and ISED = 0 Runs (XCONX must be set to zero) but does not show any results

MUD = 0 and ISED = 1 Runs but does not show any results

3. ONLY TAILINGS_CV.DAT

MUD = 1 and ISED = 0 Runs fine but XCONC must be set to zero

MUD = 0 and ISED = 1 Does not run -> ERROR: FOR DRY STACK TAILINGS DAM FAILURE. THE SWITCH "MUD" HAS TO BE 1 (ONE) IN CONT.DAT. 2-PHASE FLOW IS NOT AVAILABLE FOR DRY TAILINGS WITH NO WATER SURFACE. ONLY MUDFLOW IS SIMULATED

4. ONLY TAILINGS_STACK_DEPTH.DAT

MUD = 2 and ISED = 0 Runs fine

5. COMBINATION OF INFLOW AND TAILINGS files

I could not run any combination of INFLOW and TAILINGS files, is this correct?
