No result from addition of UNIFORM WASTE LOAD FROM BED

Trying to set up a waste load from the bed but it doesn't seem to work. Any value and combination, high flow or high concentration do not produce new results from a run without the waste load. Attached the *.scn file, values there are just to test the option to add a uniform waste load from the bed. Am I missing something?

Hi Lara, I see you have waste loads applied at multiple layers. Are you using a 3D model? Is the bed load applied in the bottom-most layer? I'm not sure what happens if you try to apply a bed load somewhere half-way in the water column but it is an easy test to try.

Hello Lora,

Yes, the model is 3D.

The bed load is applied to the bottom-most layer (using the option "uniform waste load at bed" at the discharges tab in the WAQ GUI).

The waste load you see at the different layers are from the discharge points (representing rivers), so they are not applied to the whole grid/bed. The waste load from rivers are distributed vertically as well according to the depth of the river (so they are not just at the surface).
