Final answer:
Coastal flood engineers survey tidal patterns instead of cross sections to understand the timing and intensity of coastal flooding events.
Step-by-step explanation:
Coastal flood engineers survey tidal patterns instead of cross sections.
Tidal patterns refer to the movement of ocean tides, which are caused by the gravitational forces of the Moon and the Sun on Earth's oceans. Tidal patterns can help engineers understand the timing and intensity of coastal flooding events.
By studying tidal patterns, coastal flood engineers can develop strategies to mitigate the impact of flooding and protect coastal communities.
