Is it us? Or does it feel like we visited your inbox just yesterday? 

Since you last heard from us, we have been busy helping clients with a variety of testing, modeling and design support. (This video shows you what that looks like.) We have attended some conferences and technical meet-ups. (Even if they are virtual, make sure you say hello!) And we also received some exciting news—see the first story below.

No matter how fast the hours in a day pass, we still have time to discuss all of your flow-related needs. Give us a call or submit your inquiry online. We're here to help. 

Now, without further ado, here is this month's newsletter round-up.


Congratulations to Benjamin Mater and Alden's Team Devil Fish for being named the grand prize winner in the American-Made Challenges Fish Protection Prize.

This multi-stage competition, led by the U.S. Department of Energy Water Power Technologies Office and the U.S. Bureau of Reclamation, sought innovations to advance fish exclusion technology to protect fish from threats produced by water infrastructure.

Watch the video to learn more about Ben's project, "Making a Deal with the Devil Fish: Biometric-Informed Screening Technology."

For many students this year, summer internships looked a lot different than in past years—if they happened at all. We were fortunate, however, to have a great crew working with us from schools like Worcester Polytechnic Institute, University of Massachusetts, Northeastern University, and Ohio State University.

Tufts University was represented by another one of our interns who told us how researching nanobubbles this summer helped to solidify her career path.

Day of Service: Alden Supports AFS Virtual Stream Clean-Up 

Nearly 110 pounds of trash was removed from Chaffins Brook in support of the AFS Virtual Stream Clean-Up Event. Chaffins Brook runs through Alden's property and has provided water for many of Alden's testing capabilities since 1894.

Thank you to our volunteers who came out to help.



Using LiDAR for River Engineering

From self-driving cars to 3D scanners, LiDAR technology can "see" its surroundings in incredible detail. The high resolution data provided by LiDAR can be used to create detailed hydraulic models.

In 1911, a contract was awarded to professor David Gallup of WPI to build and test various aircraft propeller designs. Nine propellers were tested using Alden's rotating boom where they were mounted above one side of the boom. A plate measured water drag under the other side to indicate the propeller’s thrust. Four of these original propellers are on display in our Holden lobby; the remaining originals can be found at the Smithsonian National Air and Space Museum.
