GEOLOGY

Detailed explanation-1: -Suspended load is composed of fine sediment particles suspended and transported through the stream. These materials are too large to be dissolved, but too small to lie on the bed of the stream (Mangelsdorf, 1990). Stream flow keeps these suspended materials, such as clay and silt, from settling on the stream bed.

Detailed explanation-2: -The coarsest sediment, consisting of boulders and cobbles as well as sand, moves on or near the bed of the stream and is the bed load of the river.

Detailed explanation-3: -Bed load refers to the discharge of sediment particles which are too heavy to be suspended by the turbulent action of the flow. These particles move by rolling, sliding and skipping (“saltation”) along the stream bed.

Detailed explanation-4: -Alluvium. All material moved and deposited by streams is termed alluvium. Alluvial rivers are those streams whose bed and banks consist of alluvium, and can be divided into three main types: braided, meandering and straight channels.

Detailed explanation-5: -Bedload transport is a specific form of sediment transport, which involves coarse particles (sand, gravel or coarser particles) rolling or saltating along the streambed.
