Component

To meet federal compliances with the Clean Water Act, erosion control blankets (ECB) are commonly installed on construction sites to control stormwater erosion and assist with reestablishing vegetation following land disturbances along highways. A research project was conducted for the Missouri Department of Transportation (MoDOT) to develop ECB guidelines for slope applications. An ECB design process for conditions representative of Missouri was developed using insight gained through an extensive literature review and the study of common ECB product acceptance and design guidelines. The Revised Universal Soil Loss Equation (RUSLE) was used as the foundation for the ECB design process and minimum performance requirements were established from existing literature. Extensive geologic information was used with ArcGIS to develop a digital map of erodibility for the state of Missouri. Erosivity maps were also developed for Missouri using ArcGIS and a map of the product of erodibility and erosivity was developed. Average values of this product for the different physiographic regions of Missouri were used to develop ECB design matrices. The development of the design matrices accounted for the complexity of ECBs typically being part of a larger stormwater erosion prevention plan.

This paper was sponsored by TRB committee AFB60 Standing Committee on Hydrology and Hydraulics. Alternate title: Development of Design Matrices for Erosion Control Blankets for Missouri Hydrology and Geology.
