Here, the accuracy of Ripple model is examined by analysing the terraint agreement metics and FIM from HAND and Ripple. There are 11 metrics calculated for each NWM reach model, including avg_inundation_overlap, avg_flow_area_overlap, avg_top_width_agreement, avg_flow_area_agreement, avg_hydraulic_radius_agreement, avg_r_squared, avg_spectral_angle, avg_spectral_correlation, avg_correlation, avg_max_cross_correlation, and avg_thalweg_elevation_difference. A description of the metrics can be found here: https://ripple1d.readthedocs.io/en/stable/tech_summary.html#model-and-nwm-network-conflation.
