Jan 01, 2011 We measured the kinematics of sprinting and characterized differences in grain size distribution and surface strength of the soil in both habitats. Although wash sand had a surface strength 15.4 6.2 kPa that was more than three times that of dune sand 4.7 2.1 kPa, both species ran with similar sprinting performance on the two types of soil.

the sand, and 2 the water level in the borehole was allowed to drop and the sand would heave up the borehole when the clean out string was removed. The best way to drill loose saturated sands is to use bentonite or polymer-enhanced drill fluid and drill bits that minimize jetting disturbance. The other important factor when drilling with fluid is
