Coastal Erosion in the Gulf of Thailand

State of the Environment in the Asia and Pacific Coastal Zones and Effects of Global Change

“…Pumping up groundwater has caused land subsidence around the Bangkok area and the Chao Phraya river mouth, which have undergone more than 60 cm of subsidence between the 1960s and 1980s. This has resulted in severe coastal erosion, and the shoreline retreat amounted to 700 m until the early 1990s (Vongvisessomjai et al 1996). That subsidence has been stabilized since 1993 by regulation of groundwater pumping.…”

Coastal vulnerability to typhoon inundation in the Bay of Bangkok, Thailand? Evidence from carbonate boulder deposits on Ko Larn island

“…Virtually no sediment aggradation and accelerated compaction owing to withdrawal from the groundwater aquifer over recent decades have caused significant subsidence of the deltaic plain, including around Bangkok which now lies at just 1.5 m above m.s.l. Coastal erosion and a drastic reduction in mangrove cover have simultaneously been experienced on the delta front (Vongvisessomjai et al, 1996;Rokugawa et al, 2006;Uehara et al, 2010). This has led to maximum shoreline retreat of more than 1 km by 2005 west of the Chao Phraya river mouth (Saito et al, 2007).…”

Mangroves and Sediment Dynamics Along the Coasts of Southern Thailand

“…Several coastal segments have undergone extensive progression due to sediment accretion whilst erosion also occurred elsewhere (Vongvisessomjai et al 1996), particularly, along the Gulf coastline where used to be mangrove-dominated. In addition, growing awareness of mangrove degradation and the importance of their ecosystems has created demand for mangrove rehabilitation and afforestation programs in the country (Kongsangchai 1995;Havanond 1995).…”
