Hello Everyone!! 1) I am trying to calibrate a 2D TUFLOW model, after the simulation run. Actually, I have water surface elevation data from the field but I don't have any data for daily averaged discharge. So, I tried 50 year event, 100 year event and 200 year event and also different Manning's for roughness but I am not sure about my result. How can I calibrate my model for having the best results? 2) There is a confidence interval in the calibration target. What is the best number for the interval? Does it depend on any thing? Thanks in advance!
