I would ask if the streamflow is sensitive to the locations of demand sites on the river? and also, should I put the gauge station in the accurate location (Lat and Long) on the river or it does not matter?

Streamflow will be affected not by the locations of the demand sites, but by the locations of the withdrawals and returns of the demand sites. The gauge station should be placed in the correct location relative to other components of the model. IE if your gauge in reality is downstream of the return for Demand Site A and upstream of the withdrawal for Demand Site B, it should also be between the two in your model. It doesn't matter if it's in exactly the right lat-long in your model, as long as it's in the correct position relative to all inputs and outputs.

Thank you so much for your response, I appreciate it. actually, I solved this problem. Now, I am trying to do the calibration with PEST depending on Parameters such as Soil water capacity, Deep water capacity, Deep conductivity, ...etc I noticed no change in the simulated streamflow when I change the value. Do you recommend to do something regarding that?
