J&S Shoreline - Erosion Control/Rip Rap

Rip Rap & Shoreline Step. with Wheel Ramps. Granite Rip Rap & Tennesee River Rock. Multiple Shoreline Step Styles to choose from to install into rock. Shape Bank to obtain proper Slope and Stability. Shoreline Shaping (area used to access bank only) upon completion of project. Install Non Woven Geotextile Fabric to prevent further Bank Erosion.

Protection against Wave-based Erosion

The maximum recommended slope of a random-placed armor stone revetment is 1.5 horizontal to 1 vertical. Slopes greater than this will tend to be unstable. A 1.5H to 1V slope results in the smallest stable footprint along the shore. Where possible, revetment slopes should be selected to match the existing bluff/bank slope's stable angle of repose.

Guidelines for Installing Rolled Erosion Control Products ...

Available hydraulic data confirms RECPs meet, and under certain conditions, can exceed the shear stress rating of rock rip rap. Some estimates indicate that installation of a turf reinforcement mat can be one-third the cost of eight-inch rock riprap for the same level of erosion control. 1(Lancaster et.al.) In many cases RECPs can also be ...

Installation guidelines - DuPont™ Typar® | DuPont UK

When placing rip-rap or gabions, start at toe and work up the slope to prevent sliding. Install rip-rap smoothly, without dropping it heavily onto DuPont™ Typar®. To ensure good fabric-to-soil contact, first of all place a layer of bedding material (gravel) on DuPont™ Typar®. This layer will also help prevent puncturing by heavy rip-rap.

Culverts & Causeways

the exit of the culvert. Because the slope influences the actual length of the barrel, an approximation of the barrel length is usually necessary to begin the design process. The barrel slope is the actual slope of the barrel which is the difference of the inlet and outfall ends of the culvert divided by the length of the culvert. Table 1.
