Final answer:
The area behind recognized levees is referred to as a 'levee-protected area,' which safeguards the hinterland from flooding, akin to the fertile floodplains of ancient civilizations.
Step-by-step explanation:
The area behind recognized levees is designated as levee-protected area. A levee is a natural or artificial embankment that protects land from river floods and overflows by blocking water from reaching the levee-protected zone. Understanding this dichotomy echoes historical contexts like the abundant black silt of the 'Kemet' in ancient Egypt, which made the land fertile when the Nile overflowed, contrasting with the 'Deshret', or barren desert lands. The levee-protected area benefits from such flood control measures, securing the hinterlands from the kinds of seasonal flooding that influenced ancient civilizations and their agriculture.
