...climate). The presence of the new highway embankment will not change the depth or duration of flooding over the existing road. 156. Downstream of the existing Manakau Stream bridge, the model shows that minor changes dissipate well within the proposed designation for the main design event. 157. Peak velocities in some parts of the modelled realignments for the main design event reach approximately 3m/s compared to 2m/s peaks in the baseline situation. This is the result of realig...
