  2. Deposition (geology) - Wikipedia

    en.wikipedia.org/wiki/Deposition_(geology)

    Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

  3. Sedimentation - Wikipedia

    en.wikipedia.org/wiki/Sedimentation

    However, the term is more particularly applied to the deposition of sediments, and in the strictest sense, it applies only to the mechanical deposition of sediment particles from an initial suspension in air or water. Sedimentation results in the formation of depositional landforms and the rocks that constitute the sedimentary record. [6]

  4. Sedimentary structures - Wikipedia

    en.wikipedia.org/wiki/Sedimentary_structures

    Soft sediment deformation (possibly a seismite) in Dead Sea sediments, Israel. Soft-sediment deformation structures or SSD, is a consequence of the loading of wet sediment as burial continues after deposition. The heavier sediment "squeezes" the water out of the underlying sediment due to its own weight. There are three common variants of SSD:

  5. Sediment - Wikipedia

    en.wikipedia.org/wiki/Sediment

    Sediment is a solid material that is transported to a new location where it is deposited. [1] It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

  6. Sedimentation enhancing strategy - Wikipedia

    en.wikipedia.org/wiki/Sedimentation_enhancing...

    Sediment deposition occurs when the water flow slows down, as the water no longer has the energy to carry heavier sediment particles and so they sink. [28] Examples of strategies that stimulate low energy conditions are semi-permeable structures made of materials such as wood, twigs and brushwood. Ems-Dollard estuary

  7. Point bar - Wikipedia

    en.wikipedia.org/wiki/Point_bar

    Any fluid, including water in a stream, can only flow around a bend in vortex flow. [1] In vortex flow the speed of the fluid is fastest where the radius of the flow is smallest, and slowest where the radius is greatest. (Tropical cyclones, tornadoes, and the spinning motion of water as it escapes down a drain are all visible examples of vortex ...

  8. River delta - Wikipedia

    en.wikipedia.org/wiki/River_delta

    Where the river water is nearly equal in density to the basin water, the delta is characterized by homopycnal flow, in which the river water rapidly mixes with basin water and abruptly dumps most of its sediment load. Where the river water has a higher density than basin water, typically from a heavy load of sediment, the delta is characterized ...

  9. Aggradation - Wikipedia

    en.wikipedia.org/wiki/Aggradation

    Aggradation (or alluviation) is the term used in geology for the increase in land elevation, typically in a river system, due to the deposition of sediment. Aggradation occurs in areas in which the supply of sediment is greater than the amount of material that the system is able to transport .
