Water-Sediment Interface

Posted on September 11th, 2013

The water-sediment interface is an important component in nutrient dynamics. The main goal is to understand and model principal processes that enhance removal of nutrients. Figure 1 Shows a flow chart that represents one modeling approach. Starting with a backwater area, we identify the reactions and biological processes to create graphs that show the fluxes […]

Species Transport Models

Posted on September 11th, 2013

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 […]

Hydrodynamics and Nutrient Modeling

Posted on September 11th, 2013

Researchers at LACMRERS are linking the use of hydrodynamics (the study of fluids in motion) and nutrient modeling on the Upper Mississippi River System (UMRS). Biological communities in a large river system are mainly controlled by a complex interplay of biological, physical, and chemical processes that shape aquatic ecosystems. This growing area of research will […]

Mussels as Sensors

Posted on September 11th, 2013

As filter feeders, mussels serve as an early warning system for pollutants and sediments in Mississippi River, much like the “canary in the coal mine.” Native freshwater mussels perform essential ecological functions in aquatic systems. They can influence nutrient cycling, because they transfer nutrients from the water column to the riverbed. The mussels require constant […]

Water-Quality Monitoring Sensor Network

Posted on September 11th, 2013

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 […]

On the Trail of Nitrates

Posted on September 11th, 2013

by John Riehl Office of Postdoctoral Scholars University of Iowa Graduate College The Mississippi River—one of the defining physical features in North America—serves as a vital transportation corridor for much of the United States and provides drinking water for those who live along its banks. Significant changes in the river jeopardize its future. Excess plant […]

Rivers as Bridges

Posted on August 19th, 2013

The Mississippi River, which holds such an important place in North America’s geography, ecology, and culture, is helping build bridges between the United States and China. For the second year in a row, the Lucille A. Carver Mississippi Riverside Environmental Research Station (LACMRERS) welcomed some of China’s finest high school students, who had come to […]

What’s New at LACMRERS?

Posted on August 19th, 2013

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 […]
