摘要: AbstractRegional downstream hydraulic geometry equations are developed using flow with a 1.5-year recurrence interval, and corresponding widths, depths, velocities. The study includes 634 gauge stations located across Canada grouped by characteristics that affect or correlated bank bed stability. Jack-knife analysis was done to test the predictive capabilities of each grouping. For width prediction, grouping data geology vegetative improved predictions in 14 15 categories, drainage mode deposition groupings showing best results. Grouping showed improvement among noncontiguous categories when considering all variables (width, depth, velocity). These investigated further. demonstrates classifying local vegetation improves eq...
