1. A 200 cm borehole log of a limestone is shown in Figure. Find the RQD and the core recovery ratio. Classify the limestone according to RQD classification. Core run total length - 200 cm No Recovery recovery 5.25 cm 43 cm 18 cm 18 cm 29.5 cm 37.5 cm Mechanical break caused by drilling No pieces > 10 cm 2. A rock core of limestone is 3 in. in diameter and 6 in. long is loaded to failure in an confined compression testing machine. If the failure load P was 60,150 lb, what is the unconfined compression strength (UCS) o of the limestone sample? Calculate the UCS in psi, kPa, and MPa. Classify the rock according to Deere & Miller, 1966

Sediment transport

Sediment transport or Soil transport is the movement of solid particles, usually due to the combination of gravitational forces acting on the sediment, and the movement of the liquid at which the sediment enters. Soil erosion occurs in natural systems where the particles are sandstones (sand, rocks), mud, or clay; the liquid is air, water, or ice; and the gravitational force that works to move particles to the landing surface. Sediment transportation or soil migration due to the movement of liquids occurs in rivers, lakes, lakes, oceans, and other bodies of water as a result of currents and waves. Transportation is also caused by glaciers as they flow, and to places on earth under the influence of wind. Soil erosion due to gravity alone is possible in most sloping areas, including hills, scarves, cliffs, and the continental shelf — the continental boundary of the slope.
