RECP Slope Protection Design Procedures

Many designers use the Universal Soil Loss Equation or revisions thereof along with designated "C" or Cover factors for RECPs in determining RECP performance in specific slope protection applications. The following charts provide general recommendations for RECP slope protection applications based on slope gradient. More specific recommendations accounting for varying slope lengths, different soil types, local rainfall quantities/intensities, and other important factors are available from the product manufacturer.

This website provides charts consisting of products that each manufacturer typically recommends for the application parameters inputted. Once you have located the chart with the materials listed for your desired application, there is a convenient website link provided that will take you to the manufacturer's website where you can obtain additional product information and specific design data.

The ECTC does not endorse or recommend the individual products or applications listed in the following charts. The numbers information, performance values and product recommendation provided by individual manufacturers are the sole responsibility of that manufacturer and are not necessarily the views of the ECTC.

Slope Gradient Selection Chart

First selection you will need to make is the gradient of the slope you are designing protection for. Click on the appropriate range of slopes listed below. A description of the calculations typically used in slope erosion protection design are available for your reference.

If you are designing an erosion control system for a flat or relatively level surface, chose the slope application. Next you will be asked to select the slope gradient. Choose 5:1 for flat or relatively level surfaces.
