Study explores impacts of a warming climate on global snowfall patterns
Posted
NASA awarded Ardeshir Ebtehaj $2.9 million to provide the longest and the most accurate satellite record of global snowfall. Ebtehaj is an associate professor and researcher in the Department of Civil, Environmental, and Geo- Engineering (CEGE) at the University of Minnesota.
Summertime is fieldwork time: Stream sampling
Posted
Summertime is fieldwork time! Here researchers and students step into a stream for a lesson on the United States Geological Survey protocols for stream sampling. Students learned how to collect samples from the thalwag, the line that connects the deepest points of the stream. They also learned how to measure a stream's velocity, depth, cross-section, and how to log that information into a mobile GIS data collection program.
Trees affect stormwater
Posted
Have you noticed trees in St. Paul parks wearing foil cumberbunds? The foil is protecting instrumentation designed to monitor the flow of sap within the trees. That data, along with several other data points about the trees, will help researchers learn more about the role trees play in urban watersheds.
How is our environment affected by wide use of antibiotics?
Posted
When the COVID-19 pandemic arose, the use of antibiotics soared. Levels of use evened out as we learned more about how the virus is transmitted. People concerned about water, however, are still concerned about the large amounts of antibiotics introduced into the environment and how they might move into and through our water systems. Zihang Wang, a graduate student advised by Bill Arnold, is taking aim at this question with support from a Hsiao Shaw-Lundquist Fellowship.
The next generation of transportation engineers: Ben Rosenblad
Posted
Starting at the University of Minnesota College of Science and Engineering, Benjamin Rosenblad (BCE 2023) was not even aware that transportation was a specialty within Civil Engineering. Four years later, he found himself heading off to graduate school to study Next Generation Transportation Systems with the benefit of a competitive and highly prestigious fellowship from the National Science Foundation Graduate Research Fellowship Program (NSF GRFP).
CAVs are coming; $15 mil will ease the transition
Posted
Assistant Professor Raphael Stern is part of the team of researchers awarded $15 million by the U.S. Department of Transportation to help lead the transition to connected and automated vehicles (CAVs). Led by the University of Michigan, the team includes UMN’s Center for Transportation Studies (CTS) and will leverage the experience of the MnCAV Ecosystem, drawing on UMN’s unique strengths to conduct transportation research concerning equity, public perception and trust, the connected environment, vulnerable road users, and cold weather conditions.
Protecting Clean Water: Faculty awarded $2.1 million to study opportunistic pathogens and disinfection byproducts in US drinking water systems
Posted
Pathogens (i.e., microorganisms that can make people sick) and disinfection byproducts (DBPs; potentially toxic chemicals formed when disinfectants like chlorine are added to water) are two classes of contaminants that are of concern in public water systems. Hozalski, et al., will examine opportunistic pathogens or OPs and contaminants that occur as byproducts of disinfection.
Tapping into Random Motion: Art in Engineering

Vaughan Voller taps dance troupe to communicate about his research into patterns of movement in nature.
To disinfect or not to disinfect, is that the question?
Posted
A recent (May 2023) article by several researchers, including CEGE’s own Bill Arnold, raised a warning about overuse of disinfectants. The use of disinfectants went way up during and after the COVID-19 pandemic. The issue has garnered interest from the media. Is this widespread use doing more harm than good?
Kimberly Hill Studies Particles That Can Bring Down Mountains
Posted
Dramatic landslides can capture popular attention. Kimberly Hill’s work helps us understand the physics behind such dramatic slides and, more importantly, how we might improve prevention efforts and mitigate the consequences.
