water quality calibration

Posts: 1
Hi there,

I've been getting mix review on how to calibrate water quality model. Some say to leave all parameters at boundary to be zero and some seem to say to inject some concentration at the boundary. Are these both options correct? or is one option more advisable than the other?

Wouldn't setting zero concentration at the boundary just causes specific parameter to decay until it reaches zero? or would it reach an equilibrium at some stage.

Thanks for helping emoticon

This very much depends on the problem you are trying to study:
- If there are no sources inside the model, the exchange over the boundary will cause it to disappear from the model in the long run
- For substances like salinity, a useful boundary condition depends on whether your model represents a marine environment or a freshwater environment
- etc.

Could you describe the modelling problem you are studying? Also, the term calibration is usually used for finding the right values for process parameters and the like, whereas from your description I get the impression that you are looking for the way to set up your model, based on - probably - a small amount of field data only.
