Coastal Geomorphic Response to Future Sea-level Rice and Its Implication for the Low-lying Areas of Bangkok Metropolis

Abstract

Evidences on the relative sea-level rise in a tidal mangrove areas of this shoreline are useful to compile the measured and assumed rates of sea-level rise over the land for predicted conditions in the future and to compare the charts indicating the movements of the local sea-level change in the historical trend. In the low-lying areas of Bangkok Metropolis, an increase in sea-level of at least 1m is accepted for the next 100 years due to the warming effect of present super-interglacial. The most serious current problem of Bangkok now is related to the excessive exploitation of groundwater which has resulted in wide-scale subsidence and groundwater contamination. In the Bangkok metropolis areas, a combination of subsidence and sea-level rise will seriously affect residential area, pollution of surface water and groundwater, flooding, wastewater drainage and treatment, agricultural land, and industrial and commercial activities in the foreseeable future.
