Abstract:
Erosion control is a critical aspect of any Georgia Department of Transportation (GDOT) construction project, with the extreme negative impacts of high sediment loads in natural waterways having been well documented. A variety of erosion control products are available for use, including geotextiles made from natural or synthetic fibers, concrete, bituminous treated roving, seed and sod, wood mulch, and soil binders. Specifically, erosion control in channels requires permanent or semi-permanent erosion control measures, with GDOT’s three most commonly implemented measures being concrete channel lining, rip rap channel lining, and turf reinforcement mats (TRMs). This work examines the newest guidelines for the development of a ditch protection program, including estimation of the coefficient of roughness and permissible shear stresses for a variety of lining types. Recommendations are made regarding the best selection for the critical model values.
