Here, water velocity is reduced, and it is retained long enough to allow suspended sediments to sink to the bottom of the chamber Next ... Gradually, gravity pulls the water beneath the surface, and ...
The observed NIR absorption can partly be explained by absorption of minerogenic particles, whereas the contribution of organic detritus to the NIR absorption is still mostly unknown. BANSE, K., C. P.
Suspension - small particles such as silts and clays are suspended in the flow of the water. Saltation – where small pieces of shingle or large sand grains are bounced along the sea bed.
