Does anyone know if documentation exists concerning the magnitude and rate of decay-related, non load-dependent settlement that can occur in a peat layer exposed to oxygen due to a drop in water table? The peat has an organic content of 60 to 90+%, is pre-consolidated to 1.5 to 3 ksf, and is currently below the water table, but a few feet (perhaps 4 feet) of the layer could become exposed due to drought conditions or lowering of the water table near new stormwater ponds to be constructed. The peat is covered by 5 to 10 feet of clean sand. We anticipate seasonal dry periods which could expose part of the peat to air for 6 months or more. Is there a reliable way to estimate this decay related settlement?
