Instead of cross sections, what do coastal flood engineers survey?

Coastal flood engineers survey transects as a means of effectively measuring and assessing coastal areas. Transects are straight lines used to analyze and gather data across varied environments, specifically in the context of coastal and floodplain management. By using transects, engineers can collect information on elevation, cross slopes, vegetation, and other important factors that influence flood risk and coastal erosion. This method provides a clearer understanding of how water interacts with different topographies, which is essential in making informed decisions for floodplain management and mitigation strategies.

The other options do not align with the specific practices used in surveying coastal areas for floodplain management and risk assessment. Zones refer to defined areas often used in planning or regulation but do not focus on the physical measurements taken in the field. Sections and quadrants are not standard surveying terms in this context, as they do not convey the same level of detail or application that transects provide in understanding coastal dynamics.
