16 AN ENGINEERED ROCKED RIFFLE
FLOW 4 20 1 1 Largest stones are placed near crest and on downstream face but must be well-choked. Upstream face is in compression (due to flow)

17 AN ENGINEERED ROCKED RIFFLE
Newbury says the backwater should be 1/3 the total height of the structure to dissipate energy & pass sediment through the system. FLOW Physical model Colorado State University showed that the highest shear stress starts at the crest & goes for a distance of 1/6 of the downstream face length.

18 ENGINEERED ROCK RIFFLES WITH ALL STONES IN COMPRESSION TWO TYPES OF COMPRESSION A: END TO END (typically track-walked in) B: IMBRICATE (to place in overlapping order like roof shingles)

50 There is great info available on Newbury Rocked Riffles
TAKE A BOB NEWBURY CLASS!!! Bob Newbury’s out-of-print “Stream Analysis & Fish Habitat Design Manual” is available at ftp://ftp.lgl.com/pub/ under ‘Stream Analysis.pdf’ When constructing a series of Newbury RR Bob always puts a NRR “at grade” (buried) at the DS end of the project to protect against DS headcuts, max height of a NRR is 1.5 ft, and Bob always puts a tailwater of 1/3 the total height of the upstream NRR on the upstream NRR. This provides energy dissipation into the tailwater pool, & provides sediment continuity (sediment does not deposit between NRR’s and the stream does not meander and flank the DS NRR )
