Good morning
I have some rivers within my large study area. Along these rivers I have some monitoring stations with water level data in 10 years. For transient state I think I have to assign 3rd type boundary condition for these rivers with time-varying function.
In the link below I found this situation for a river as a boundary of the area and that the northern and southern points have the ID 1 and 2.

Now I have a river lying in the area with 4 monitoring stations. So I have a powerfunction file with 4 powerfunctions (ID = 1-4). I don't know how to link these 4 ID with 4 points, and to interpolate along the river. Is there any difference in transfer rate between steady state and transient state?

I'm waiting for any help, please as detailed as possible.
Thanks a lot!

Thuy.
