WebIn apportioning amongst the subreaches the total storage volume computed for each discharge, the profile of cross-secticTal areas was assumed linear, i.e., changes in subreach storage over a time step were assumed proportional to subreach length. WebAn increase in vertical flux at sites in the lower subreach is attributed to the movement of lateral subsurface waters originating from the adjacent floodplain. This lateral‐moving …

Web27 Feb 2024 · Channel characteristics and streambed coverage were averaged for each subreach. Three substrate metrics were derived from pebble counts from each subreach: the median particle size (D50), and the particle sizes that 16% (D16) and 84% (D84) of particles were smaller than (Olsen et al., 2005). Models were fit with maximum likelihood … Web15 Sep 2016 · The study reach can be divided into an upper and lower subreach based primarily on the valley floor relief ( Fig. 3 ). The change in relief occurs ~ 400 m downstream of a knickpoint on the longitudinal profile, which coincides with an abrupt steepening of the channel slope (160% increase). Web15 Feb 2024 · The biggest drop in the peak tracer concentrations occurred between sampling points A and B despite this area being the shortest section among the three subreaches, which could be attributed to the significant impact of a larger pond pattern on the solutes dilution. l\u0027etoile french immersion school portland
