I'm purchasing equipment to do some permeability testing on sand, but in the future we might need to do some testing on fine grained soils. I'm planning on purchasing a constant/falling head permeater so I can use it for either. Can someone explain why a falling head test is recommended for...
I need to find standard lithologic patterns for soils and bedrock. USCS standard patterns are preferable, but I've also read there are standard DOT patterns. I need them for CAD dwgs. Is there anywhere I can download standard soil hatch patterns or do I just "copy" the ones I've found online by...

I need to find angle of repose values for wet and dry sand. So far, I've found friction angle values for dry sand which should be equal to angle of repose. (I found a reference from 1919 but would like something newer). I need to put these in a report along with recommendation that we test for...
