Lesson plan
Drop structure
of Leasburg Diversion Dam, part of the Rio Grande Project, is an example of a vertical hard basin, the most basic form of a drop structure, designed to dissipate energy. A drop structure, also known as a grade control, bed sill, check dam, or weir, is a manmade structure, typically small and built on minor streams, or as part of a dam's spillway, to pass water to a lower elevation while controlling the energy and velocity of the water as it passes over. Unlike most dams, drop structures are usually not built for water impoundment, diversion, or raising the water level. Mostly built on watercourses with steep gradients, they serve other purposes such as water oxygenation and erosion prevention.
