Tried a different swing on the dredge arm last Tuesday and got 20% more material per hour

Been running the same scoop angle for 3 years on the Mississippi River job until a old timer told me to tilt the cutter head down 5 degrees more, and now I'm wondering why nobody else around here tries it since it cuts way down on recirculation, has anyone else experimented with arm pitch on a sandy bottom?

Read something similar in a dredging forum last week actually.

Yep, saw that same thread. The 40% settling rate shift was wild, but people argued the test setup wasn't real-world enough (like, too controlled). Still, makes you wonder if anyone's bothered to check decibel levels at the job site.

Figured I'd chime in here because I've been digging into this whole thing from a completely different direction, @the_julia. Most folks are looking at the technical side or the maintenance schedules, but I think what's getting overlooked is the noise pollution angle and how it actually messes with sediment settling rates in weird ways. Ran across a study last month that tested sound frequencies on cohesion and it threw their whole timeline off by like 40%. Not saying that's your exact situation, but it made me wonder if the crews are even accounting for ambient noise levels when they plan their dredging cycles. Might be worth asking the guys on site if they've noticed any patterns with equipment running nearby.
