Table A2. Summary of Consequences for 1 in 1,000 AEP Flood Event without Breach (Bridges) Notes: (1) Time of arrival and time to flood peak are relevant to the beginning of the storm event. (2) The bridge is not overtopped by the flood. (3) The bridge is overtopped by the flood and the detailed information is summarised in the corresponding road damage in Table A3. (4) Estimations of PAR and Potential Loss of Life are based on the Campbell method (Ref. 27). Waikino Railway Bridge and Criterion Bridge are expected to be closed before a severe storm event and thus excluded in the estimation of PAR and Potential Loss of Life.
