Earthquake Hydrogeology
A new study shows earthquakes can shake up permeability and change groundwater behavior. Groundwater systems generally are made up of layers of permeable rock called aquifers separated by low-permeability layers called aquitards. When an earthquake shakes things up, the structure of these layers can change and cause an increase in stream flow as water is […]
Cactus to the Pollution Rescue
Could the humble cactus be the solution to our plastic waste problem? Chemical engineering professor Sandra Pascoe Ortiz is beta-testing an edible, biodegradable packaging material made from the juice of prickly pear cactus leaves. The juice “is a natural polymer that can be improved by combining certain substances to give it a similar appearance and […]

Concrete – The Most Popular Man-Made Material on Earth
I’m not surprised that concrete is the most used building material, but I was surprised to find it’s the second most used substance behind water. I don’t think I’ve ever had a construction project where we didn’t use concrete. A fascinating article talks about the past, present and future uses of concrete. – Jason Savage, DTC […]
Fish Friendly Hydro Power
A recent ASME article noted that in 2012 a Department of Energy study identified 54,000 Non-Powered Dams, dams with changes of elevation of 15 feet or higher, which could provide 13 gigawatts of power, enough to power 5 million homes. That potential is to say the least staggering. The primary reason that these “small dams” are […]

Rolling Bridge – Good Design Never Gets Old
An 18th century bridge design could be taking on a new life through London architect Thomas Randall-Page. His rolling bridge design is a low tech and elegant solution that requires no motors or electricity. I could try to describe how it works, but this animation from a curbed.com article tells all. For a mechanical engineer this […]
FEATURED TESTIMONIAL – Beyond Helpful
“I didn’t finish college. Having history as a CAD drafter for architecture firms, I got a job at a small civil engineering firm in Florida. I stayed there 4 years, learning and growing into a design engineer before moving to California where I remained in the field for another ten years. However; without a degree, […]
