in the hydrodynamic and water properties is possible to impose cyclic boundaries but is assumed that all open boundaries are cyclic.

Dear Francisco,
it is not possible to define directly a value variable in time in the border. The only way is to active the assimilation module. The assimilation module allow the user to relax any property (flow or water) in any cell using the follow formula
dP/dt = (P(assimilation) - P) / Decay Time
If the decay time is very low the model impose in a cell the value P(assimilation) if the decay is very large the final result is equal to the model result. This type of methodology is use usually to impose boundary solution in a progressive way in space.

You need all the information use to define a grid that is in the Bahymetry plus
a block were you impose very low decay times in the boundary points. The temperature is always a 3D property heaven if the model has only one layer.
