peat compaction floodplain

The dominant factors influencingpeat compactionare: (1) organic-matter content, (2) stress imposed on apeatlayer, and, to a lesser extent, (3) plant species composition. In an alluvial setting, crevasse splays and natural levees are sites that are most susceptible to high amounts ofpeat compactionat short timescales (10 0 –10 2 years ...

Only if the maximumpeat compactionpotential at a certain location has been reached, while at a nearby location on thefloodplainrates of subsidence due topeat compactionare still relatively high, differentialpeat compactionmay lead to gradient advantages. This may affect spatial sedimentation patterns on afloodplain.

Contribution of peat compaction to relative sea level rise

Modern and forecasted flooding of deltas is accelerated by subsidence of Holocene deposits. Subsidence caused by tectonics, isostasy, sedimentcompactionand anthropogenic processes, combined with eustatic sea-level rise, results in drowning and increasedfloodrisk within densely populated deltas. Many deltaic sedimentary successions include substantial amounts ofpeat, which is …

Effects of peat compaction on delta evolution: A review on

Jan 01, 2009·Peat compactionand formation are key processes in delta evolution, especially in distal parts with relatively high accommodation rates where thickpeatlayers are formed in thefloodbasins. The way and magnitude by whichpeat compactionand formation influence delta architecture strongly depend on temporal and spatial scale.

Subsidence due topeat compactionmay have important implications in alluvial floodplains, because it leads to wetland loss, land inundation, and damage to buildings and infrastructure. Furthermore, it potentially influences spatial and temporal river sedimentation patterns, and hence the evolution of alluvial floodplains. As the vast majority of peatlands occur in cold temperate regions,...

Soilcompactionresults from human activities that press down on soil and eliminate much of the pore space between soil particles. Thiscompactionand the loss of pore space reduces the soil's ability to store water meaning that less water is absorbed by the soil when it rains.
