Modeling the Erosion and Swelling of the Sides of Transverse Cracks in Embankment Dams

AbstractConcentrated 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 the critical shear stress of the soil, and the crack will widen. For...
