What is what does bfe mean?

BFE stands for "Boundary, Finite Element". In the context of fluid mechanics and water resources engineering, BFE is the term used to refer to the elevation of the boundary of a body of water or floodplain. In simpler terms, it is the level at which water or floodwater is expected to reach during a flood event. BFE is determined by using various factors such as the anticipated flood level, topography of the area, and the probability of a flood event. It is an important metric used in flood insurance, floodplain management, and flood hazard mitigation.
