Abstract: Erosion rates of unsaturated compacted Na‐montmorillonite clays are measured under a range of tractive stresses from surface flows in a rectangular flume. The degree of saturation of compacted samples ranges from 0.52–0.97. ...

Abstract: Erosion rates of unsaturated compacted sodium and calcium montmorillonite clays are measured under a range of tractive shear stresses. The calcium montmorillonite is treated with additives calcium chloride and sodium ...
