In April, Spirit entered an area composed of three or more layers of soil with differing pastel hues hiding beneath a darker sand blanket. Scientists dubbed the site “Troy.” Spirit’s rotating wheels dug themselves more than hub deep at the site. The rover team has spent weeks studying

The landslide elements of Day 2 at EGU were split between two sessions on landslide forecasting and two on landslide risk. The latter is of comparatively little interest to me, and I had a load of work to do and meetings to attend, so I only attended the morning sessions. In terms of landslide forecasting, there was some pretty good stuff presented. I would say that some speakers need to think a little more about their audience - using endless meteorological acronyms might work well if you aThis may be due to because the maximum density of soil is greatly influenced by the type of soil as cohesionless soils attain a much higher density than cohesive soil. The improvement in CBR value of soil is obtained by mixing ...Evaluation of Interaction Properties of Geosynthetics in Cohesive Soils: LTRC Reinforced-Soil Test Wall By Khalid Farrag, Ph.D., P.E. and Mark Morvant, P.E.
