Dam Failures in the U.S. – the Risks and Risk Management 26:32

11d ago26:32

26:32

Dam failures are frightening, and they can become disasters. Just how common – or uncommon – are the failures of dams in the U.S.? What are the contributing factors and are there ways we mitigate them? To learn the facts about dam failures, we talk with John Roche, who is Chief of the Dam Safety Permits Division of the Maryland Department of the En…

The Eads Bridge at 150: A Story of Innovation in Design, Materials, and International Finance 30:08

1M ago30:08

30:08

The Eads Bridge, opened in 1874, is the oldest functioning bridge across the Mississippi River. This St. Louis crossing, named after its designer/builder, James Eads, pioneered the use of steel, then a new material; the construction of long-span arches without falsework; and deep underwater foundations. Eads himself led the creation of an elaborate…

19:20

Intercity bus terminals are key links in the national bus network. We’re losing some these terminals due to pressures for more lucrative land uses. The announced closing of Chicago’s downtown Greyhound station will be impactful because about half a million passengers pass through it annually. How important are these terminals, not just locally, but…

Big Infrastructure for Big Science - The Deep Underground Neutrino Experiment 26:59

3M ago26:59

26:59

Scientific research needs supporting infrastructure – some small, some big, but rarely simple. The Deep Underground Neutrino Experiment – DUNE – will study the neutrino, one of the smallest atomic particles that is a fundamental building block of the universe. DUNE will send neutrinos generated at the Long Baseline Neutrino Facility near Chicago 80…

Let Drones Do It – Taking on Bridge Inspection 18:53

4M ago18:53

18:53

Bridge inspectors like to get up close and personal to detect small defects that could grow into disasters. The configuration of bridges – their size, height, and locations – can make the job difficult and dangerous. But rapid advances in aerial drones are making it possible to inspect difficult-to-access areas of bridges quickly and safely, reduci…

Delivering Energy on Demand: Grid-Scale Storage 20:56

8M ago20:56

20:56

Energy from wind and solar sources is available when nature permits, but the demand for energy is based on the cyclical needs of people and their activities. To make renewable energy work, and to manage the normal daily mismatches between supply and demand, we need to shift energy in time from when it is available to when it is needed. That calls f…

When Permafrost isn’t Permanent – Building Infrastructure in Cold Regions 17:42

9M ago17:42

17:42

In very cold places, like Alaska, Northern parts of Canada and Europe, building infrastructure means building on permafrost, perennially frozen ground. Permafrost provides reliable foundations for buildings and highways as long as it remains frozen. But warming temperatures driven by climate change may threaten existing and new infrastructure found…

The Bay Lights – Bridges as Art 20:35

10M ago20:35

20:35

Spectacular bridges can be focal points of their host cities, reminding us that unique infrastructure can also be unique art. Lighting those bridges can carry their aesthetic value into the night. In 2013, the San Francisco-Oakland Bay Bridge was illuminated with a 25,000-LED dynamic display called The Bay Lights, and its public appeal kept it ligh…

Giving Streets Back to People – Tactical Urbanism in Atlanta 22:11

12M ago22:11

22:11

Some U.S. Cities are taking back streets from exclusive use by motor vehicles to protect and prioritize vulnerable road users – pedestrians and bicyclists – and to enhance neighborhood livability. This process is advanced under the banner of Complete Streets, streets designed and operated for all users. Atlanta, Georgia’s variation is called Tactic…

Getting PFAS Out of Our Drinking Water (fixed) 20:33

1y ago20:33

20:33

PFAS, per- and polyfluoroalkyl substances, the forever chemicals, are commonly used as protective coatings because they resist heat, stains and water. Because PFAS do not normally degrade in the environment, when products containing them are discarded, they become nearly ubiquitous pollutants in our water supply. Can they be removed? If so, how can…

18:42

Fluctuations in water levels on our inland waterways system can affect the movement of bulk freight, particularly agricultural products. Low waters, as occurred in the fall of 2022 on the lower Mississippi River, limited the flow of freight and increased shipper costs. To learn more about the causes, consequences, and responses to such disruptions,…

US railroads are highly efficient at moving freight. Indeed, our freight rail system is the envy of the world, but sometimes accidents occur. When train derailments occur, the outcome is usually minor, but occasionally more serious problems arise. To understand the causes and prevention of train derailments, we’re talking with Dr. Allan Zarembski, …
