Scour in cohesive soils has been an obstacle for engineers and designers for quite some time because, unlike non-cohesive soils, viable erosion testing devices and well-accepted scourability guidelines have been severely lacking. This online course curated by Don Parnell, PE summarizes an advanced case study reported by the Federal Highway Administration in 2015 on the development and performance of an erosion testing device that simulates open channel flow on a small scale. Design approaches are also recommended for estimating scour for a wide range of cohesive soils. Specifically, topics covered in this online engineering course include cohesive soils, erosion testing, slaking, direct force gauge, log-law velocity profile, bed shear stress, critical shear stress, erosion rate, and more.
