The most common drainage method in an urbanized setting is a trapezoidal drainage channel. Drainage channels pose various hydraulic demands on the engineer - flow level limitations, high hydraulic velocities and damaging scour potential. The Conlock^® product line offers solid solutions to these and other issues by providing choices in the selection of Manning’s n values, shear stress resistance and hard armor protection. Wildlife habitat is afforded due to the Conlock* products ability to vegetate.
