  • Peat - Wikipedia2019-1-31 · 2500 years BP the area now named the Netherlands was largely covered with peat. Drainage, causing compaction and oxidation and excavation have reduced peatlands to about 3,356 km 2 (1,296 sq mi) or 10% of the land area, mostly used as meadows. Drainage and excavation have lowered the surface of the peatlands.

  • The relative contribution of peat compaction and For example, if peat compaction is the main contributor to total land subsidence, lighter construction materials could be used, a long pre-loading phase may apply, or it may be decided that the area should not be built on at all (e.g., Long and Boylan, 2013).

  • Soil compaction - Wikipedia2019-2-3 · In geotechnical engineering, soil compaction is the process in which a stress applied to a soil causes densifiion as air is displaced from the pores between the soil grains. When stress is applied that causes densifiion due to water (or other liquid)

  • Contribution of peat compaction to relative sea‐level The model quantifies spatial and temporal trends in peat compaction within fluvial‐dominated Holocene flood basin sequences of different compositions. Subsidence due to peat compaction is highly variable in time and space, with local rates of up to 15 mm/yr, depending on sedimentary sequence.

  • Effects of peat compaction on delta evolution: A Peat compaction and formation are key processes in delta evolution, especially in distal parts with relatively high accommodation rates where thick peat layers are formed in the flood basins. The way and magnitude by which peat compaction and formation influence delta architecture strongly depend on temporal and spatial scale.
