Engineering Out Loud

The Klamath River is transforming after four dams were removed in 2024. In this episode, we join the research team studying the impacts of the dam removals on plant and algae. Hear from the students and faculty about what they are learning at the confluence of engineering and ecology.   BONUS CONTENT  River Rebalance (story)  Mark Bransom Heads the Historic Klamath Dam Removals (video)  How Engineers Decommissioned Four Dams Along the Klamath River (lecture video)  Rewilding the Klamath (story)  What it Takes to Take Down a Dam (podcast) 

The removal of four dams from the Klamath River was a once-in-a-lifetime opportunity to capture the interplay of science, engineering, and culture. Desirée Tullos, professor of water resources engineering at Oregon State University assembled a collaborative team that unites Western science and traditional ecological knowledge of Indigenous people.   BONUS CONTENT:  What it Takes to Take Down a Dam (podcast) Unrestricted Flow (video about River Engineering field trip on the Klamath)   

This is a historic year on the Klamath River, where the biggest dam removal in the U.S. is underway. The hope for the monumental engineering project is that it will restore some balance to a damaged ecological system. We hear from Mark Bransom, who is overseeing the demolition and restoration, about why and how it’s happening and some of the challenges of the project.

Will swarms of unmanned aerial vehicles be able to aid humans in wildland firefighting or package delivery? Research summarized in a new paper in Field Robotics represents a big step towards realizing such a future. In this interview, Professor Julie A. Adams describes the research showing that one person can supervise more than 100 autonomous ground and aerial robots. 

The final episode of the season occupies a time of transition, as spinoff company Espiku ramps up. We get an update on two systems that received patents and a third that could provide an environmentally benign technology for extracting lithium. We also hear from four graduating students who reflect on their experiences. Bonus content: Tapping technology to ensure the world has enough clean water 

The pandemic didn’t stop Bahman Abbasi’s desalination research. In this third episode, we learn about the successful lab-scale demonstration of his team’s technology and the next steps toward its commercialization. Plus, the team takes on a new project to clean up wastewater from oil and gas production. Bonus content:  Espiku, OSU spin-off company  Turning freshwater into saltwater, Bend Source article 

In the second episode of this four-part season, we travel to Bend, Oregon to visit the Water and Energy Technologies Laboratory and meet the team that is inventing a new technology to desalinate water. Bahman Abbassi, associate professor of mechanical engineering, talks about building the lab from the ground up, and graduate student Mohammed Elhashimi demonstrates their system to desalinate water.  Bonus content:  Quest for Clean Water (story, video)  Water and Energy Technologies Laboratory 

Can turning seawater into drinking water be a cost-effective way to provide clean, fresh water for the growing numbers of people facing water scarcity? Bahman Abbasi, associate professor of mechanical engineering, is taking up that challenge with a mobile, modular, solar-powered, desalination system. This is the first episode in a four-part season.

What is Oregon doing to prepare for earthquakes, tsunamis, and wildfire? Researchers at Oregon State University are working with the state Legislature to help them make informed decisions about how to prepare for natural hazards. 

Can plants fortify Oregon’s coastal dunes against storm surge? Meagan Wengrove, assistant professor of coastal and ocean engineering, built scale versions of dunes in one of the world’s largest wave flumes to find out.

After a major disaster, hidden amid the rubble and debris are precious clues about the extreme forcesstructures were subjected to, and exactly what caused them to fail. How can researchers collect this perishable data before it’s swept away? Michael Olsen, professor of geomatics and technical director of the NHERI RAPID Facility, talks about a major effort to get crucial technology into the hands of reconnaissance experts quickly, wherever disaster strikes. https://beav.es/URn

What will it take for Oregon to recover after a magnitude 9.0 Cascadia subduction zone earthquake? Among other things, it will need a major airport to receive the tons of relief supplies from around the world. Prof. Armin Stuedlein and a research team from Oregon State University conducted crucial testing that guided engineers with big plans to make sure one of the runways at Portland International Airport survives the shaking. engineering.oregonstate.edu/season-11-engineering-natural-disasters/saving-pdx-s11e5

Wildfires that devastate mountain communities have the potential to foul the water distribution system running underneath residential structures. But knowing which water pipes have been affected is challenging. Erica Fischer, assistant professor of structural engineering, is working with a team of engineers and scientists to develop and test sensors that can easily indicate if water pipes need to be replaced following a fire.

How do engineers fight wildfires? With fire. David Blunck, associate professor of mechanical engineering, is trying to better understand and predict the behavior of embers that spread blazes. To do this, he has to burn a few of his own.

What happens to bridges, buildings, and pipelines when the soil holding them up behaves like a liquid? Ben Mason, associate professor geotechnical engineering, has traveled the world doing post-earthquake reconnaissance to find out and make us better prepared for impending earthquakes.

The long-feared 9.0 magnitude Cascadia subduction zone earthquake, which seismologists say is inevitable, will damage or destroy large swaths of Oregon’s electrical grid. How long will it take to get the juice flowing again? Weeks? Months? Professor Ted Brekken and his team are applying high-powered simulations to find out and to identify which parts of the system should be hardened against the quake at any cost. 

How do you manage a COVID-19 surge? When intensive care units are beyond capacity, health care workers are stretched thin, and life-saving equipment is in short supply, there are a lot of tough choices to be made, and quickly. Joe Agor, assistant professor of industrial engineering, is gathering the data on how hospitals prepared and responded to the pandemic, as well as how their patients fared, with the goal of helping to better manage surge capacity for future pandemics or disasters.

How can we get a more diverse group of young people interested in computer science? Focus on equity, says Jill Hubbard, instructor of computer science and co-principal investigator of a multi-university project to change how computer science is taught in high school, funded by the National Science Foundation. Over 40 schools are part of a program to make computer science more welcoming to underrepresented groups.

Can middle schoolers learn computer science concepts using tabletop games? How about during a pandemic, when classroom interaction takes place remotely? Researchers in computer science and education are working closely with teachers to develop an innovative curriculum designed to broaden participation in computer science classes.

What can wastewater tell us about the spread of disease? Could the coronavirus’ signature RNA sequence tip public health officials to where the next COVID-19 outbreaks will occur? In this episode, we’ll talk to two researchers who are leading the effort to monitor Oregon’s wastewater streams for coronavirus, in partnership with treatment facilities throughout the state.
