Performance Assessment of a RECP-Lined Channel 15 Years Following Installation
During the autumn of 1998, a severely eroded diversion channel was repaired using a mixture of rolled erosion control products (RECPs). In order to address the severe erosion, fabric-formed concrete revetment was installed in the bottom of the perennially flowing channel, whereas a woven polypropylene high performance turf reinforcement mat was installed along channel banks subjected to high shear stresses during the design run-off event. A non-woven polypropylene conventional turf reinforcement mat was used on channel banks subjected to moderate shear stresses. The channel lining performance was assessed during a visual reconnaissance conducted in April 2014, after 15 years in service. Although a few areas of distress were observed, the channel linings have performed satisfactorily. Photographs and visual observations of the RECPs made during a detailed reconnaissance conducted in spring 2014 are provided, as well as the author's opinions regarding the overall performance and suggestions for future designs.
