Cross Sec­tion C‑C¹ of Point Bar 3 and Pool 4 to scale 1:5,000 @A3

These cross-sec­tions and long sec­tion show the point bar, pool and riffle fea­tures in a more real­ist­ic way. The cross-sec­tions are at a scale of 1:5000 with dis­tance in metres along the x axis and height in metres AOD up the y axis. The long sec­tion has the same ver­tic­al scale but dis­tance has been com­pressed due to the length of the sec­tion. The new chan­nel is between 9.8m and 13.5m wide, 0.5m deep and pools are an addi­tion­al 0.5m deep.

As men­tioned in the Design Draw­ings doc­u­ment, there is some flex­ib­il­ity allowed for in the chan­nel design to cre­ate as nat­ur­al a fin­ish as pos­sible using rough sur­faces, vari­able bank angles (with­in lim­its), the place­ment and form­ing of the gravel to cre­ate the riffle and point bar fea­tures and the excav­a­tion of pools and inset berms (a lower­ing of the bank edge) to add depth and width.

Cross Sec­tion D‑D¹ of Riffle 6 (to scale 1:5000 @A3) and long sec­tion E‑E¹ from Pool 6 down the chan­nel to bey­ond Riffle 6 (com­pressed hori­zont­al scale)
