ECTC’s web site helps facilitate erosion-control design – Rolled erosion-control products are typically used in slope or channel applications. The design elements needed for both applications are provided in detail at the ECTC’s Web site, http://www.ectc.org. At the site, click to enter the section entitled “Product Selection and Design.” Once there, you will have to choose between slope or channel design. The user chooses the desired application. Once you have made your selections, the site will then direct you to the products appropriate for your project design. Feel free to contact any of the members listed on the Web site for additional information or to answer any questions you may have.
