Hydraulic performance of shallow water habitat in the Missouri River for ecological studies

Abstract

The overarching goal of this research is to evaluate the hydraulic performance of different structures found in the Missouri River for creating new shallow water habitat (SWH). Such structures include dikes found in their original form, notched dikes and chevron dikes. The hydraulic performance of the aforementioned structures will be evaluated via detailed field monitoring studies for a range of flow conditions and for different locations within the stream. In addition, a 2-D hydrodynamic model will be used to describe the flow patterns around the hydraulics structures. The code will provide for different flow conditions the flow depth and velocity variation introduced by the structures. This paper presents the first phase of this ongoing research by comparing the numerical simulations with the field measurements.
