  • Geosynthetics in Stream Restoration

    Credits: 1 PDH

    PDH Course Description:

    This course is based on the NRCS publication "Geosynthetics in Stream Restoration", providing an overview of how geosynthetics, which are synthetic materials used for soil stabilization and erosion control, can be utilized in stream restoration projects. The publication discusses the benefits of using geosynthetics, such as reducing erosion and improving water quality, and outlines the different types of geosynthetics that can be used in stream restoration, including geotextiles, geogrids, and geomembranes. The publication also provides guidance on how to design and install geosynthetics in stream restoration projects, including considerations for site selection, design specifications, and construction techniques. Overall, this course serves as a valuable resource for engineers involved in stream restoration projects who are interested in utilizing geosynthetics to improve project outcomes.
