1 West Fork Beaver River, West Point, OH. Constructed Sept. 2002 Minimal height Bendway Weirs in a gravel-cobble-sand-silt bed stream for thalweg realignment & bank stabilization in the area of an exposed high-pressure pipeline overbend.

2 Lisbon Inn 40952 State Route 154, Lisbon, OH

3 Functions of Bendway Weirs on the West Fork Beaver River: Main functions of the BW are to provide bank stabilization within the bend and realign the thalweg through the bend and center the thalweg where the pipeline overbend was exposed by erosion. The pipeline was directly protected with Submar’s patented Articulated Concrete Mattress (ACM) system.

4 SUB MAR West Fork of Beaver River West Point, OH. Pre-project. Looking US at an eroding outer bank.

5 SUB MAR NOTE: We did not build the two upstream Bendway Weirs

6 SUB MAR Close-up of Bendway Weirs

7 Looking DS at three Bendway Weirs, as constructed Sept 2002 SUB MAR Pix by derrick 9-2002

8 SUB MAR Pix by derrick 9-17-2007 Looking DS at the same 3 Bendway Weirs 5 years after construction. The well graded 18 to 24 inch stone in the BW has held up well & the outer bank exhibits a flat slope & is stable.

9 Looking US at two low elevation Bendway Weirs, two years after construction, 05/11/2004. Outer bank is stable SUB MAR

10 Five years after construction, 9/17/2007, looking US at the same two low-elevation Bendway Weirs. Note stable flat sloped vegetated bank. SUB MAR

11 SUB MAR Pix by derrick 9-17-2007 Close-up of the DS low-elevation Bendway Weir, five years after installation. Weirs are close to invisible!!

12 SUB MAR Great aquatic habitat due to the deep pools created by the Bendway Weirs. These pools were full of high quality fishes, indicating that water quality is excellent. {5 years after project completion} Pix by derrick 9-17-2007

13 WE ARE DOG TIRED, THIS PROJECT IS DONE !! Cleophus Speed Elvis Derrick
