FAILURES OF SLOPE CUTS INVOLVING MORPHOLOGICAL ZONE II The in situ moderately to highly weathered bedrock of Zone II mostly consists of medium dense to very dense, gravelly silty sands that can be expected to behave as cohesionless soils...

... is a descriptive parameter by which the percentage of sand, silt, and clay content is organized into 14 different classes based on primary particles (size < 2mm) and coarse fragments (size > 2mm). The mode of deposition and dominant texture can influence many soil properties such as the drainage (vertical...

..., a salt water base drilling fluid displays high SPEC values. A high brine content has an adverse structuring effect on dispersed clay gel systems, which increases the solute migration potential particularly in coarse textured soils ( Beal et al., 1987; Murphy and Kehew, 1984 ).
