Good morning!

I work on a seawater modelling project, trying to simulate pollution.

Through the determination of "process parameters" I try to provide depth varying values for several parameters (degradation rate constants).
When selecting "data properties", the window selection regarding "depth (constant/depth varying)" is freezed, giving no options for any selection. 
On the contrary, i have this option (depth varying) when dealing with open boundaries..
​​​​​​​
Do you have any relevant experience to solve this problem? Should I create a dedicated file with the desired values (segment function, quickin data file) or is there a simpler solution. I just need to provide different values over some of the layers.

Thank you in advance for any replies!
Have  a great day!
