Based on Book 6 of ARR2016 (Reference 2, Section 7.2.4), small vehicles can withstand flood depths of up to 0.3 m before beginning to float and therefore, flood depth over roadways is critical. The peak flood depths and levels presented in Table 16 and Table 17 indicate that flood depths of 0.3 m are exceeded at many locations in the study area during events as frequent at the 1 EY event, albeit
