DESIGN TO CONTROL EROSION IN ROADSIDE DRAINAGE CHANNELS

The findings are outlined of a project to develop criteria and design procedures for the use of aggregate or riprap linings for drainage channels suitable for conditions intermediate between those for which turf cover performs satisfactorily and those for which paved channels or pipe flumes are more economical. Riprap linings for 5 channels were designed in accordance with the procedures described in Report 108, Four of thechannels have been constructed and are performing satisfactorily. Two have been subjected to discharges approaching the design discharges without signs of erosion. Details of the drainage channels are tabulated and comments are made on the design procedure. Inspection of channels indicated that special care should be taken with regard to culverts and other transition structures leading into riprap lined drainage channels. The practical design procedures are prepared in easy-to-use tables and charts, and the channels built in accordance with the design procedures have successfully undergone considerable laboratory and field evaulation. The procedures are already being incorporated into manuals and publications on erosion control by highway agencies.
