“…The data collected in this study appear to have a bedrock-coarse-bed transition that has an intermediate intercept and gentler slope in comparison to the relations proposed by Sklar and Dietrich (1998) or Addy et al (2011). The semiarid Colorado Front Range has less discharge per drainage area, and steeper stream gradients per drainage area, than the empirical data set from Scotland (Addy et al, 2011).…”

“…This line was plotted on an S-A diagram with all of our study reaches plotted by the predominant substrate. Neither of the transition lines proposed by Sklar and Dietrich (1998) or Addy et al (2011) reliably divided bedrock from coarse-bed reaches in our study sites (Fig. 4A).…”

“…The semiarid Colorado Front Range has less discharge per drainage area, and steeper stream gradients per drainage area, than the empirical data set from Scotland (Addy et al, 2011). We interpret this to indicate that higher gradients are needed in the Front Range to create enough stream power to initiate bedrock incision.…”

“…We plotted the hypothetical transition between coarse-bed alluvial and bedrock channels as estimated by Sklar and Dietrich (1998) and Addy et al (2011) and visually assessed sites for their location relative to this line. We also developed regression power relationships for each of the predominant substrate types to compare among coefficients, exponents, and correlations.…”

River floodplains constitute an important element in the terrestrial sediment and organic carbon cycle and store variable amounts of carbon and sediment depending on a complex interplay of internal and external driving forces. Quantifying the storage in floodplains is crucial to understand their role in the sediment and carbon cascades. Unfortunately, quantitative data on floodplain storage are limited, especially at larger spatial scales. Rivers in the Scottish Highlands can provide a special case to study alluvial sediment and carbon dynamics because of the dominance of peatlands throughout the landscape, but the alluvial history of the region remains poorly understood. In this study, the floodplain sediment and soil organic carbon storage is quantified for the mountainous headwaters of the River Dee in eastern Scotland (663 km 2), based on a coring dataset of 78 floodplain crosssections. Whereas the mineral sediment storage is dominated by wandering gravel-bed river sections, most of the soil organic carbon storage can be found in anastomosing and meandering sections. The total storage for the Upper Dee catchment can be estimated at 5.2 Mt or 2306.5 Mg ha-1 of mineral sediment and 0.7 Mt or 323.3 Mg C ha-1 of soil organic carbon, which is in line with other studies on temperate river systems. Statistical analysis indicates that the storage is mostly related to the floodplain slope and the geomorphic floodplain type, which incorporates the characteristic stream power, channel morphology and the deposit type. Mapping of the geomorphic floodplain type using a simple classification scheme shows to be a powerful tool in studying the total storage and local variability of mineral sediment and soil organic carbon in floodplains.
