In 1997 a U.S. patent was granted to the U.S. Army Corps of Engineers for a new applied engineering tool and methodology called micromodeling, which uses a small-scale physical model to simulate sediment conditions in rivers and streams. Since the introduction of micromodels in 1994 by the St. Louis District Corps of Engineers, the technology has been used to address a variety of sedimentation problems and issues, among them navigation design in the Mississippi River; restoration of side channels; bridge scour in rivers and streams; improvements to detrimental flow conditions at locks and dams; siltation at water supply intakes; and the effects of dredging.
