GENERAL GEOLOGY

Detailed explanation-1: -The two main flow factors in sediment transport are the settling rate and the boundary layer shear stress 27.

Detailed explanation-2: -The sediment load may be divided into two components: that which is suspended within the water column, suspended sediment, and that which is moved along the bed of a channel, bedload.

Detailed explanation-3: -Fine sands, clay, and silt are typically transported as suspended load. The suspended load is held aloft in the water column by turbulence. The bed load is made up of sands, gravel, cobbles, and boulders. Bed load is transported by rolling, sliding, and bouncing along the bed of the channel (Allan, 1995).

Detailed explanation-4: -The suspended load is the fine-grained (clay and silt) sediment that remains in water during transportation. The bed load consists of the coarser fractions of the sediment (sands and gravels), moves by rolling, sliding, or saltation actions.

Detailed explanation-5: -Suspended load generally consists of fine sand, silt and clay size particles although larger particles (coarser sands) may be carried in the lower water column in more intense flows.
