Sedimentation enhancing strategies aim to increase sedimentation on the delta plain primarily by restoring the exchange of water and sediments between rivers and low-lying delta plains. Sedimentation enhancing strategies can be applied to encourage land elevation gain to offset sea-level rise. [19]

Within each colored area, the type of material shown is what dominates, although other materials are also likely to be present (Steven Earle, “Physical Geology”).

With the increase in fine particle content, the tailings transformed from a single particle or floc sedimentation pattern to a flocculated network sedimentation pattern. In addition, as the sedimentation and consolidation process proceeded, the tailings coarsening effect on the bottom became weaker, while the coarse-fine interlayer occurred, leading to the

The landward increase in sandstone content and bed-set amalgamation, and the up-dip transition into fluvial-dominated mouth bars, suggests that the lobes were fed by gravity flows deriving from shelf-edge deltas (e.g. Mellere et al., 2002; Petter & Steel, 2006).

· In monsoon period, similar things can be observed as the high fluctuations in water flow leave a considerable change in the sedimentation pattern before and after the monsoon period []. Apart from these factors, the sediment transport will also be influenced by the geometry and width of the channel.

· Groynes are popular hydraulic structures often used to control the erosion of banks by altering flow and sediment transport. In this paper, the effects of altering groyne orientation and spatial setup (from large to small and vice versa) on flow patterns, bed erosion, and sedimentation are numerically investigated. Studied groynes were parallel

Sediment deposition in water reservoirs has major implications for storage capacity, reservoir lifetime, and water quality. Changes in rainfall patterns and land use will consequently alter the rate of erosion and therefore have a direct effect on sedimentation rates.
