Research
The MRI promotes and engages in interdisciplinary river research that encompasses the natural sciences, social sciences, humanities, and legal field. The Institute contributes faculty, student, and equipment resources to this research. In some cases, the Institute also acts as a funding vehicle for these projects.
The Institute collaborates with many other institutions, such as the University of Texas-Arlington, U.S. Army Corps of Engineers and the National Park Service.
Research Projects

This project is monitoring the habitat of five backwaters along the river. Graduate students are conducting thesis/dissertation research in this area. Water quality, plant and animal species, and hydrology are included in the comprehensive monitoring plan for this project. Contact: Tim Cowman (Tim.Cowman@usd.edu), Missouri River Institute |

This project is sampling sites in the Bow Creek watershed to determine the potential impact of endocrine disruptor compounds originating in the Bow Creek watershed on the Missouri River. This is a collaborative project with the University of Nebraska - Omaha. Contact: Tim Cowman (Tim.Cowman@usd.edu), Missouri River Institute |

In cooperation with the National Park Service, Missouri River Institute, SD Geological Survey, Nebraska Conservation and Survey Division, and university partners, the U.S. Geological Survey began a geologic mapping project of the Missouri River corridor region along the Missouri National Recreational River (MNRR) of southeast South Dakota and northeast Nebraska. The geologic framework of the river corridor, especially the glacial and postglacial geology emphasized in this work, dominates the geomorphic and hydrogeologic bases of the physical habitat and ecology. The area of the corridor spanned by the MNRR includes several geologically significant terrains. The river valley, with a width of 3-6 km throughout most of the Dakotas and eastern Montana, expands markedly below Yankton, SD to a width of 10-16 km. The expanded reach coincides with the southernmost extent of the James River lobe of the late Wisconsinan Laurentide Ice sheet. In the uplands south of the river valley in eastern Nebraska, a much older and morphologically distinctive pre-Illinoian glacial terrain is partially mantled by loess. Both terrains include extensive glacial-buried-valley aquifers, which are contiguous with the alluvial-outwash aquifer that underlies the river and its valley.

Within the Missouri National Recreational River (MNRR) turtle populations are impacted by a number of factors which include limited access to nesting sites due to bank erosion, river bed degradation, and bank stabilization projects; flooding of nest sites, encroachment of nesting habitats by vegetation, overall reductions of suitable nesting habitat, and increased predation pressure related to high concentrations of nests within available areas. This mark-recapture study is investigating the habitat relationships, species composition, age structure, sex ratios, and abundance of turtle populations on the 59-mile segment of the MNRR.

Collaborative research between the MRI, USD Earth Science Department, and University of Texas-Arlington is documenting former channels of the Missouri River and James River (a major tributary on the 59-mile MNRR). This research is looking at how these rivers changed their flow patterns over the past few centuries. Impacts of climate change, dams, and bank stabilization are considered.
