Looking for a particular stream restoration detail (grade control)
Looking for a particular stream restoration detail (grade control)
(OP)
I've worked on stream restoration projects in the past for previous firms where we called out a grade control structure that was basically a big log that crossed the realigned creek perpendicular, with a notch cut in the log and two other logs behind it benched in at 45 degrees to hold the primary log in place. The purpose was to create a small stilling basin upstream of the log and riffle/habitat downstream of the notch, and allow us to flatten the stream's grade between logs. It worked great in the project, but for the life of me I can't remember what the dang things are "called."
Anybody know what those things are called, and if so where to find a detail of them? I can whip a detail up from scratch, but if there's an official name for them that'd help.

I haven't seen them in a while, but I know them as a "log drop structures" or a "log weirs."

Details are included, though not truly construction details, but at least something you can work with.
