I would like to sincerely welcome you to IIHR, and I hope your work here will be successful and rewarding. IIHR has the responsibility to provide staff and resources to assist and support your research activities. Our goal at IIHR Engineering Services is to provide high-quality resources that will play a key role in your […]
The IIHR Engineering Services (IES) program has developed to support the varied research and education activities at the institute. Thanks to this demanding environment, the IES team is proficient in a wide variety of areas, with excellent facilities, wide-ranging experience, and the flexibility to rapidly adapt to changing needs and tight deadlines. IIHR continues to […]
by Cornelia F. Mutel Floyd Nagler, IIHR’s founding director, focused his entire life on making a difference. One could see it in his tending of his large vegetable garden (he felt fresh foods were crucial to his family’s health). And in how he took over the pulpit when his minister traveled elsewhere (he wanted to […]
The objective of this research was to compare historical and current conditions in Pool 8 of the Mississippi River. A comparison of different discharges over different bathymetries was conducted. The results can be very helpful to restoration attempts on Pool 8. Also, they can be used to study possible management actions to restore an ecosystem. […]
In this study. an ecosystem (Round Lake) was modeled. Using 3-D tools allowed us to define flow patterns and species distribution when structures are place on the ecosystem. Figure 1 Shows distribution of mean velocity field (left) and nitrate concentration (right) for two cases: one without an island and, one with an island.
This area of research explores species transport using complex multi-physics models to understand spatial and temporal distribution on smaller and larger scales of nutrients. IIHR researchers currently use the OpenFOAM (free platform) and FLUENT models, both of which have been extended through in-house codes developed to improve mass transport. Present research covers the use of […]
IIHR’s water-quality initiative represents an unprecedented effort to monitor real-time changes in a large river in response to climatic events, agricultural trends, and other human activities. Researchers at LACMRERS have 10 Hydrolab multi-sonde water-quality monitors deployed in Pool 16 for detailed chemical analysis. The sensors provide continuous real-time monitoring of: Dissolved oxygen Temperature Specific conductance […]
There’s always something interesting happening at the Lucille A. Carver Mississippi Riverside Environmental Research Station (LACMRERS). LACMRERS is a place where people meet to study, collaborate, and learn about the Upper Mississippi River — often while having a lot of fun. Whether it’s students gathering to try out some hands-on science on the river, or […]
IIHR’s Sarah Vigmostad is part of research team working to learn more about metastatic cancer cells and how they survive the remarkable stresses of the human bloodstream.
