The potential of delta sequences for both natural and human-induced subsidence due to compaction and oxidation of peat, and hence subsidence magnitude and rate, is highly variable in time and space, mainly depending on the composition of the subsurface.

The results show that human impacts—peatland subsidence and increased suspended sediment load—on the river, estuary, and peatlands made the lower delta more prone to avulsion. The sensitivity of the system in response to human impact can to a large extent be attributed to the compaction-prone nature of peat.
