| This paper examines two classification systems, one designed by David Rosgen for a wide variety of landscapes and drainage areas, the other by David Montgomery and John Buffington which was specifically developed for use in mountainous drainage basins. The latter system is used to test two hypotheses. The first hypothesis tests whether spatial patterns of reach types along a longitudinal gradient occur randomly. The second hypothesis tests whether differences in valley width influence what reach types occur along that same gradient. Results from this study suggest that (1) certain reach types preferentially terminate into other reach types and (2) the valley width relative to the active channel width exhibits a strong signal in terms of the observed bed morphology. |
