APPLICATION OF MULTI-DIMENSIONAL NUMERICAL MODELING TO REAL WORLD COMPLEX HYDRAULIC PROBLEMS

There is a growing need to have multi-dimensional numerical modeling capability to apply to real world problems. Complex hydraulic problems in rivers, streams and coastal areas require that application tools be available to the practicing engineer for use in developing suitable alternative solutions and to provide more insight to regulators and peer reviewers. Sediment management with river engineering structures has been successfully performed around the World in both isolated and systematic ways. By proper evaluation and implementation of river engineering projects sediment problems can be alleviated. There are numerous examples of such projects around the World, such as; Lower Mississippi River, Red River Waterway, Arkansas River, and numerous small streams having systems approach applied to reduce sediment transport Additionally, localized projects when properly evaluated can solve sediment problems without causing problems to other areas in the watershed. Multiple dimensional modeling is now capable of adequately computing the hydrodynamics and sediment transport of a river reach to aid in developing a sustainable solution. The CCHE3D model was applied to the Hudson River in the vicinity of Yonkers, New York and specifically the docking area to evaluate means of moving the sediment through the area, in lieu of annua
