A more thorough explanation:

A levee is a structure built along the edge of a river to prevent flooding. It is also a place where boats can dock to load and unload goods or passengers.

1. The city built a levee along the river to protect the town from flooding during heavy rains.

2. The boat pulled up to the levee to drop off its passengers and pick up new ones.

These examples show how a levee can be used to prevent flooding and provide a safe place for boats to dock. The first example illustrates the use of a levee as a protective structure, while the second example shows how a levee can be used as a landing place for boats.
