with many drowned estuaries as the common characteristic of the submerging
shoreline.
However, it should be noted that the amount of peat soil to date is decreasing as
the result of utilization. Normally, when the swamps are drained, most of the peat
layer disappears due to subsidence by oxidation, burning, and cultivation practices,
resulting in the formation of acid sulfate soil.
