Peat

Peat producers in Finland often claim that peat is a special form of biofuel because of the relatively fast retake rate of released CO 2 if the bog is not forested for the following 100 years. Also, agricultural and forestry-drained peat bogs actively release more CO 2 annually than is released in peat energy production in Finland.

NAVER Academic The contribution of peat compaction to

ABSTRACT Provision of accommodation space for aggradation in Holocene deltaic basins is usually ascribed to eustatic sea‐level rise and/or land subsidence due to isostasy, tectonics or sediment compaction. Whereas many Holocene deltas contain peat, the relative contribution of peat compaction to total subsidence has not yet been quantified from field data covering an entire delta.

The relative contribution of peat compaction and oxidation

Sep 15, 2018Drainage of the peatland from ca 1100 CE initiated land subsidence due to peat compaction and oxidation. In the course of time, embankments had to be built to protect the subsided land from floods. From ca 1400 CE wind-powered pumps (the Dutch wind mill) were used to keep these areas dry (Van de Ven, 1993).

Geotechnical Properties of Peat in San Joaquin Delta

The San Joaquin Delta region in Central California covers about 780 square kilometres (300 square miles) of reclaimed islands and tracts and over 650 km (400 miles) of waterways and 1300 km (800 miles) of levees. Its peaty soils are some of the riches farm land in the world, but also have very undesirable geotechnical properties.

Pressure on levees is increasing, drainage conditions are deteriorating due to lowered levels, and alkali salts are tending to accumulate.
