Witryna15 lis 2024 · The ability to evaluate and predict how sediments will affect shoreline stability and coastal ecosystem functions (e.g., dune formation, sediment deposition on salt marshes) is expected to be increasingly important for communities to plan for and mitigate impacts expected with sea-level rise. Sources/Usage: Public Domain. WitrynaBecause wetlands are associated with waterlogged soils, the concentration of oxygen within sediments and the overlying water is of critical importance. The rate of oxygen diffusion into water and sediment is slow, and this (coupled with microbial and animal respiration) leads to near-anaerobic sediments within many wetlands ( Moss, 1998 ).
