  1. These are located in UBM (simple network) and NSV (complex network) rivers, Rocky Mountain National Park, Colorado. Channels with a confinement value < 0.2 are considered unconfined while those with a confinement value ≥ 0.2 are considered confined. Confined is defined as the ratio of the channel width versus the valley width
