CLIPPER WASH BANK PROTECTION

Problem

The Banks of the Clipper Wash near Dewey, A.Z. had been eroded significantly to the point that the new bank limits got very close to the adjacent road and housing.

Protection was needed before the next monsoon season. The Yavapai County Flood Control in Coordination with FEMA and Lyon Engineering were looking for options to solve the erosion control problem and restore the bank to its original limits.

Solution

A gabion groyne system was selected to protect the bank from erosion and restore the limits of the bank to its original position. Groynes are finger-like structures projecting from a riverbank, they deflect flowing water away, protect the bank from erosion and establish a more desirable channel for flood and erosion control. The outer ends of the groynes determine the line of the new bank and the spaces between Groynes were gradually filled with deposited material until the groyne structure was covered and virtually disappeared.

Groynes are structures made with gabions and reno mattresses and are filled with 4 to 8 rock. A non-woven filter fabric was placed between the gabions and the soil, adding erosion protection and preventing the migration of the fine soil material. Gabions with Polimac coating were selected as the most appropriate solution, as they offer the most protection against corrosive soils, abrasion from sediment transport and humidity.

The Polimac coated wire on the gabions is a high-performance polymer exclusive to Maccaferri that has 10 times more abrasion resistance and more protection from Ultraviolet Degradation than traditional PVC coating. The steel wire is low carbon coated with long-life Galvanization.
