Summary:

Peatlands and organic soils in Delta areas suffer from continued surface subsidence. At the same time accumulation of suspended sediments originating from these peatlands leads to poor water quality. Many researchers attribute the majority of surface subsidence of peatlands to decomposition of organic matter, particularly as a result of aerobic oxidation during periods of low groundwater level. The sediments which settle in…
