PROJECT OVERVIEW

High-Flow Channel Protection

Customer:

Peabody Coal

Location:

Somerville, Indiana

Product:

APPLICATION:

Evaluation of ShearForce 10 for replacing rock riprap in high flow areas

SITE DESCRIPTION:

Grab the slider to see "before vs after" with ShearForceTM 10

Objective

Test application for the InstaTurf ShearForce™ 10 ECTRM at protecting the highly erodible channel soils and evaluate effectiveness as a rock rip rap replacement.
 

 

A key learning from this project is the importance of installing your erosion control even beyond where you think the water flow width will be. ShearForce10 protected the ground, but as you can see, erosion occured immediately next to it.

Overview

We installed the InstaTurf ShearForce 10 at a coal mine in Indiana in September 2019 to demonstrate the erosion armoring capabilities of the product compared to rock riprap. It was installed over cool season grass mix.

Tim Lancaster revisited the site on multiple occasions to see how the ShearForce 10 product, unprotected control sections, and rock check dams held up through the winter months. 

Results

By spring 2020, severe erosion and scour had occurred in adjacent and downstream areas not protected with ShearForce™ 10. 

The ShearForce 10 test section remained solid after a long, very wet winter, whereas the unprotected control sections and riprap structures had failed.

By late May 2020, the ShearForce 10 had become fully vegetated, and now acts to permanently reinforce the grasses against future storm flow events.
