Two-Dimensional Modeling Applications for Use with Missouri River Restoration

The Missouri River Biological Opinion and the Amended Biological Opinion set forth the requirements for the creation of Missouri River shallow water habitat. A significant physical monitoring and modeling effort has been undertaken in conjunction with habitat creation. Numerous bend length two-dimensional models have been constructed with successful reproduction of hydraulics at the structure level. This paper describes the application of two-dimensional analysis at several sites along the Missouri River in support of the shallow water habitat program. The merits of two-dimensional models, model selection, ability to replicate observed hydraulics, classification of shallow water habitat with the model, design and analysis of habitat construction methods are presented.
