What is an embankment?

An embankment is defined as a bank of earth or rock raised above the natural ground surface, primarily used to hold back water or to create a barrier or support structure. This construction technique is often employed in various civil engineering projects, such as the creation of roadways, bridges, or levees. The embankment acts to elevate the surface, providing a structure that maintains its integrity under load and environmental stress.

In the context of stormwater management, embankments can play a critical role in redirecting water flows, managing runoff, and controlling flooding by creating physical barriers. The design and construction of an embankment consider factors such as the material used, slope stability, and drainage to prevent erosion and structural failures.

Understanding what constitutes an embankment is crucial for professionals in grading and drainage, as it directly impacts how they manage water in the landscape and ensure proper function of stormwater systems.
