1 Bridge Section 11.105 94.223 Existing Valley with river section put in at bridge location.

2 No upstream culverts and No Bridge 12.834 94.266Both upstream storage areas removed by areas being re-contoured as in proposal, No bridge has been modelled.

3 Bridge Option 1A + CC 12.445 94.099Bridge 1A as set out in proposal with both upstream storage areas removed by areas being re-contoured.

4 Bridge 1A with culverts 10.856 94.066 Proposed bridge 1A is modelled into the existing layout of the valley.

5 Bridge Option 1B + CC 12.461 94.205Bridge 1B as set out in proposal with both upstream storage areas removed by areas being re-contoured

6 Bridge Design Option 3B - upstream storage kept with New Flood Storage 11.677 94.622

Top upstream storage area kept (to CS7). Storage area immediately upstream of the proposed bridge location is re-graded, spill 18-19 lowered to 93.75, Spill 21-22 being raised to 95m AOD.

7 Bridge Design Option 3B - new contours high spill 18-19 11.929 96.619

Both upstream storage removed by areas being re-contoured as proposed, Flood Storage being provided by Spill 18-19 being raised to 96m AOD.

8 Bridge Design Option 3B - New contour design with New Flood Storage 11.793 94.688

Both upstream storage removed by areas being re-contoured as proposed, Flood Storage being provided by Spill 18-19 being lowered to 93.75, and Spill 21-22 being raised to 95.0m AOD.

9 Bridge Design Option 3B - New contour design with New Flood Storage + new cut 11.756 94.672

Both upstream storage removed by areas being re-contoured as proposed, Flood Storage being provided by Spill 18-19 being lowered to 93.75, and Spill 21-22 being raised to 95.0m AOD. The right hand bank of CS14 has been regraded to 93.25m AOD to provide extra storage capacity.

10 Bridge Design Option 3B with culverts 11.104 94.220 Proposed Bridge 3B is modelled into the existing layout of the valley.
