Man-made embankments, such as roads or levees, represent an overland flow hydraulic structure that retains, directs, and controls flow. Flow is retained as it is impounded behind the embankment, directed to flow adjacent to the embankment towards natural stream channels, and controlled in a weir-like fashion as it flows over the top of the embankment. Embankments significantly alter the flow characteristics of a watershed and are important features to be able to model.
