Surface NMR as part of an integrated geophysical survey in Thailand

Within the Thai-Gem research project 'Recommenriations for Site Investigations of Waste Disposal Sites and Contaminated Sites in Thailand' (WADIS) an integrated geophysical survey has been carried out in the Dan Khun Thot region near the provincial capital of Nakhon Ratchasima (Khorat). This area, located on Khorat Plateau in north-east Thailand, is characterised by increased land salinisation as a probable consequence of deforestation. Saline soil is the origin of various environmental problems, such as shortage of freshwater during the dry season, soil degradation md decrease of crop.
