English term or phrase:flumes
Hi, everyone, and hope all's well. Merry Christmas, Happy Hanukkah and Happy Kwanza to all, with love in our hearts, peace, serenity and compassion.
The context where I have the term flumes follows below:
"Flumes allow for accurate measurement of seepage rate but do not provide a means for collecting material. Regardless of the method used to measure the seepage rate (weir, flume or bucket and stop watch), a sample of the seepage water should be collected and allowed to settle out, at least overnight, to check for the presence of any suspended material (fines) being transported (piping or seepage erosion). Drainage pipes within a downstream embankment provide a convenient method for collecting and measuring seepage. Care must be taken that such pipes are properly filtered to prevent piping and if not it is even more important that the flow from the drain pipe(s) be routed through a weir to allow capture of any material being moved."
