^a Distance from the river mouth to the top of the reach
^b Slope and catchment area derived from the 5 m grid NEXTMap Digital Terrain Model (Intermap Technologies, 2007).
^c Reach-averaged widths and depths derived as the mean of all measured widths and depths in each reach (n = 2 to 10).
^d Uncertainty on width and depth is derived as the standard error of the mean of the values in each reach.
