Summary:

Multi temporal high resolution satellite imagery was used to identify the peat-coastal setback of Bengkalis Island, Indonesia. Shuttle Radar Topography Mission DEM was used to estimate the geomorphology of the peatland. Multi temporal topographic survey using RTK-GPS, peat core samplings, and ground water level measurements were conducted to clarify the geomorphology change and carbon storage of the peatland. Recent coastline change and long term coastline change were analyzed with high resolution satellite images; SPOT-6 and WorldView3. The average annual setback changed from 11.93 m to 23.37 m. Over the long term, average annual setback…
