Riffle + Vane = Viffle


John was recently out and about, checking up on his Sulphur Creek project.  Here’s a snap of a ‘Viffle’ in action.  A Viffle is what you get when you take a tradtional ‘Newbury Rock Riffle’ grade control structure and cross it with a rock vane control.   So you get all of that lovely step-down, scour pool grade control action of the Newbury Rock Riffle, along with the current, re-directive control of a rock vane. 

Here’s a sample typical detailing what’s going on below the surface.
