This PR focuses on the position of three scripts in the post-processing and updating the longitudinal filtering parameters. First, a new script has been written to address the thalweg notch adjustment, separated from the nonmonotonic adjustment script. Second, the post-processing has been changed in a way that thalweg_notches_adjustment and logitudinal_flow_adjustment will be run before bathymetry_adjustment. Then, nonmonotonic_adjustment will be run after the src_subdivision section. The second purpose of this PR is to update the longitudinal_adjustment parameters and replace the minimum filter with the lowest 10-percentile of the discharge on the rating curve.

    • thalweg_notches_adjustment.py
