Simulating constant DOC relase over time for chemostat study

[Bisesh Joshi]

Hi Glenn,

I'm trying to simulate a chemostat condition in which DOC is released from SOM used as a mineral continuously and is available for heterotrophic reactions. Right now, I'm assigning the volume fraction of SOM based on the average % of soil organic matter. The DOC finishes in the reactive transport system with simulation is run for more than 10 years. 

Please let me know if you have any suggestions regarding this.

Thank you.

Best regards,

Bisesh

Bisesh,

 

I don’t fully understand the issue below. Are you saying the DOC is depleted after 10 years? I would need to see the reaction network and rate expressions. If the SOM concentration is based on a mineral that is dissolving, you could set the mineral RATE_CONSTANT to zero.
