Carrie Davis: Playing in the Mud
by Shianne Gruss Penny Davis likes to say that her daughter Caroline never grew out of the sandbox. Today, Carrie Davis, an assistant research scientist at IIHR— Hydroscience & Engineering, often spends her days knee-deep in riverbeds, monitoring water quality. Before joining IIHR as a postdoc in 2011, Davis was a contract geologist for Iowa […]
Success among Friends
IIHR research assistant Ruben LLamas helped design a curved spiral antenna for the multidisciplinary freshwater mussel research initiative at the University of Iowa.
STEM/K-12 Education
LACMRERS is an important educational resource for students in many fields of study, including engineering, biology, English, and more. A water-quality class is held every summer at LACMRERS, with significant time spent in the field on the Mississippi River. Short courses for international students are a popular new innovation at LACMRERS, and a recent STEM […]
A Celebration of Discovery
LACMRERS welcomed hundreds of K-12 students and their families (and Herky!) to the IExploreSTEM Festival, giving students the chance to experience science, technology, engineering, and math (STEM) hands-on.
Mussels Serve as Water-Quality Sensors
Why would a mollusk wear a backpack? For decades, IIHR has had a love affair with the freshwater mussel. Once students dig their first mussel from the Mississippi River mud, they are hooked. IIHR researchers have led countless mussel-based research projects, including efforts to re-establish endangered species in Midwestern rivers. At LACMRERS, a display of […]
IIHR Hosts Honors Workshop
IIHR hosted one of 16 Honors Primetime workshops held for incoming first-year honors students before the official start of classes this fall.
Species Suitability Indices
Habitat studies evaluate a particular ecosystem to define whether or not it is suitable for a particular species to survive. The studies use biological and hydrodynamic parameters to characterize optimal conditions for a species’ survival. The figure below shows one of the parameters that describes Habitat Suitability for vegetation in Pool 8 in the Mississippi […]
Historical Modeling of Pool Eight
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. […]
