What is the function of a 'levee'?

A levee serves as a barrier specifically designed to control the flow of water, primarily to prevent flooding and manage excess water from rivers, lakes, or even the sea. It is a crucial element in flood management, particularly in areas prone to heavy rainfall or where water bodies are likely to overflow their banks. By creating a physical separation between the water and the surrounding land, levees help protect infrastructure, agricultural land, and communities from water-related damage.

In contrast, the other choices relate to different functions that do not pertain to the purpose of a levee. For instance, structures that support heavy buildings are more about architectural integrity rather than water management. Facilities for recreation focus on providing spaces for leisure activities, while forms of transportation relate to systems that facilitate the movement of people or goods. None of these options capture the essential function of a levee, which is to act as a protective barrier against water inundation.
