... calibre of the load decreases downstream. Calibre of load 72 170 189 153 102.5 69 300 203.5 128 130 164.5 130 88.3 106 107 188 There is no correlation between the calibre of the load and the stream downstream but this may be because there we took random samples from the river and we only took six samples. There a slight decrease in the size of the bed load as the stream moves downstream. Relationships 1). There is a negative relationship between the discharge and the gradient. Discharge 0.01 0.04 0.04 0.04 0.06 0.05 0.19 0.1 0.2 0.17 0.18 0.13 0.26 0.34 0.15 0.33 Gradient 7 15 2 12 5 10 2 5 2 9 0 2 3 2 4 19 There is a strong negative pattern between the discharge and the gradient. The discharge increases downstream and the gradient decreases downstream. This proves my hypothesis. There is a strong pattern because on the upper course of the river there is a steep gradient, small number of volume and small amount of debris. As the stream moves towards the middle course there is plenty of debris for the work of erosion as the gradient becomes less steep and at the lower ...
