Abstract: Concentrated leak erosion occurs in transverse cracks in dams when the reservoir rises above the base of the cracks. As water flows through the crack, the sides of the crack will erode if the hydraulic shear stress exceeds ...

Abstract: Reaeration is a primary path of reoxygenation in streams, fundamental to environmental and ecological integrity. Previous laboratory studies of reaeration rates in subcritical flows showed large scatter in results, with ...
