John Poullain, PE
This three-hour online course provides general guidelines and practices for protecting streambanks from erosion and correcting erosion problems. The nature of streams, erosion and bank failure processes and methods for reducing damages to the streambed and bank is discussed. The course covers vegetative stabilization and structural methods including riprap, gabions, checkdams and bulkheads. Control of surface water is also necessary to prevent sheet and rill erosion of streambank slopes. Typical methods used to manage over bank flows including earth berms, diversion ditches and terraces as well as vegetation are also discussed. The emphasis of the course is on natural streams and creeks. Navigation channels are not considered but some of the measures considered here for streambank protection are appropriate for larger waterways. State or Federal permit approval is required.
The student will become familiar with methods and techniques used to protect streambanks from erosion and overbank drainage in order to reduce soil erosion and runoff into downstream waterways. The student will better understand the application of interception and diversion methods such as ditches, berms and benches. The student will also become familiar with the nature of streams and factors causing streambank erosion and failure. Basic guidance in the selection of the most appropriate method to use and the advantages and disadvantages are discussed.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
