As we finalize this month's message, we are surrounded by scenes of pumpkins and autumn leaves...covered in snow. Yes, folks. It's Snow-tober in Massachusetts.

How's the weather where you are?

In this month's newsletter round-up, we are taking a look at unraveling the mystery of 316(b) compliance alternatives that require optimization studies. If that's not your thing, spend 15 minutes learning about the use of CFD as a Design Tool for Nature-Like Fishways. And if that's not your thing, maybe you have a marine renewable energy idea that you'd like to advance through a program like TEAMER. 

Whatever your thing may be, we're delighted to pop into your inbox to bring you a variety show of flow-related topics. Stay tuned and we'll do it again next month, "snow" matter what. 


Optimization Studies, the 316(b) Rule, and How It Affects You

Alden staff have been involved in all aspects of the §316(b) Rule for fish screening at cooling water intakes—a rule that advises facilities on how to implement or improve their fish screening technology. Yet, many operators struggle with understanding how to move forward, particularly when it comes to compliance measures, alternatives, and optimization studies.   

That's where we jump in to help.

CFD as a Tool for "Nature-Like" Fishway Design

The decommissioning of the Saccarappa hydroelectric project required the design and implementation of modernized fish passage. Through the use of CFD modeling, our team helped to guide the engineering of the design. But the project was not as straight-forward as one would think. Making fish passage functional in a river that sees a wide range of flows required as much art as it did engineering.
