  • Recently, the pollution of soil and groundwater becomes a serious social problem, and geophysical exploration methods have been introduced as a remedial investigation method of subsurface. Digital technologies such as personal computer have revolutionized our ability to acquire large volume of data in a short term, and to produce more reliable results for subsurface image. Also, color graphics easily visualizes the survey results in a more understandable manner, and it is widely used for not only characterizing the contaminated subsurface but also monitoring contaminant and remedial process. In this paper, electrical resistivity and electromagnetic (EM) surveys were carried out in order to understand characteristics of waste landfills, and the applicability of geophysical prospecting to site assessment of waste landfill was also tested. According to the result, electrical resistivity and electromagnetic (EM) surveys were effective in estimating distribution of the leachate plume.

  • Since the liberation in 1945, Korean specialists in the field of geological science and mineral resources engineering have developed two disciplines through the cooperation and competition with each other. Specialists both in the geophysics and in the geophysical exploration, who share much, have developed their own fields deeper and broader. Since the late 1990s, specialists in both fields felt the need for an independent society to deal with their fields and discussed the establishment of such a society. In 1997, they discussed to establish a unified society which integrates both fields instead of separated societies. However, in 1998, the Korean Geophysical Society and the Korean Society of Exploration Geophysicists were separately established due to some practical problems. During 7 ~ 8 years since the establishment of the two societies, many members of the two societies intended that the two societies should integrate into a single comprehensive society based on the facts that many fields of each society are overlapped and naturally many members of one society are the members of the other society. The leaders of the two societies accepted these opinions also and began to discuss thoroughly the integration from 2005. Eventually, in 2007, the two societies successfully integrated and established the Korean Society of Earth and Exploration Geophysicists. The Korean Society of Earth and Exploration Geophysicists continues to cooperate and compete with other societies of geological science and mineral resources engineering in Korea and in circumpacific area including Asia, Oceania and Americas, contributing to the development of geophysics and geophysical exploration.

  • In Japan, geophysical exploration methods have been widely applied to civil engineering and construction fields for a long time. In particular, seismic refraction has long played a significant role in geotechnical site investigations for tunnels, dams and landslides. However, our growing interest on the social and natural environment makes the methods available and its application fields diversify. Digital technologies such as personal computer have revolutionized our ability to acquire large volumes of data rapidly, and to produce more reliable results for subsurface image. Also, color graphics easily visualizes survey results In a more understandable manner, These days geophysical methods are essential to assessing grouting effects, predicting the front of tunnel cutting face, monitoring the movement, pollution and purification process of groundwater. Now three-dimensional exploration techniques have developed for the site characterization in civil engineering and construction needs.

  • Among the geophysical exploration methods, electromagnetic method(EM) has the broadest range of instrumental systems and remarkable range of applications. There are a lot of available techniques and instruments which have different depth of investigation and resolution depending on the operating frequency and source-receiver configuration. Furthermore, it is very easy to apply on the engineering and environmental problems since modern EM equipments are remarkably portable, considering their sophistication. Even though electromagnetic theory is very complex and not easy to understand, rapid avances in recent computer technology have made it possible to conduct accurate forward modeling and inversion of various EM exploration data. Here, we are going to provide brief theoretical principles, survey techniques and case histories of some selected EM methods that can be applied to geotechnical and environmental problems in Korea.
