Develop Guidance for Selecting and Cost-Effective Application of Temporary Erosion Control Methods

Project Description

The results of this project provided the Texas Department of Transportation (TxDOT) with specific information necessary to determine the cost-effectiveness of erosion control products and methods that could result in significant cost savings while improving compliance with federal stormwater regulations. The TxDOT/TTI Hydraulics, Sedimentation, and Erosion Control Laboratory evaluated performance factors based on how well each product reduced sediment loss and established vegetation.

The researchers found that price does not always correlate to initial soil protection performance in slope erosion control. Channel protection products with greater longevity continued to offer performance protection at high shear stresses. By applying the concept of product longevity to soil-loss data, researchers calculated lifetime product performance that estimated the total soil amount protected by the product over time. Many of the less-expensive, non-manufactured erosion control products and techniques evaluated proved to be effective for controlling sediment loss and establishing vegetation.
