SOURCE BLOCK - Unwanted Bed Load flux

Good afternoon,

I want to model a suspended load release since I want to assimilate it to plastic particles. The flow is in a steady state. I have the regular geometry of the Arno River as the basechain.

The bed load needs to be fixed, so I didn't include the bed load block.

I tried using a suspended load discharge from a cross-section, but the model crashed, and I couldn't fix it. So, I tried using the EXTERNAL_SOURCE block.

In this case, the problem is that once the model reaches the time step of the release, a bed load flux appears, causing the concentration curve to no longer be Gaussian but a curve with a plateau.

How can I fix this?

Thank you for your time.
