Mussel-Rope Part Two

Further to our recent mailout where we discussed mussel rope at perched/overhanging structures, it’s now time to look at mussel-rope when placed within culverts. Mussel-rope is one of the tools that can be used to help improve fish passage where fast, laminar...

Understanding Mussel-Rope

Understanding Mussel-rope Part 1 Many culverts are barriers to fish due to being perched/overhanging or having fast laminar flow. In the video below, Tim demonstrates how mussel-rope can improve fish passage at perched/overhanging structures. The rope simulates...

Comparing Baffle Types in Round Culvert

Hi everyone,  We hope you are staying safe and well.  As shared a short while back, we have started using Computation Fluid Dynamics (CFD) to solidify what we already knew about culvert/weir baffles and their fish passage improvement features. CFD is a...
