Engineering geological mapping of the Banda Aceh alluvial basin, Northern Sumatra, Indonesia
Summary An engineering geological regional mapping project, carried out as part of a British Government technical assistance programme with the Geological Survey of Indonesia, is described. The project area is approximately 200 square kilometres of thick, lithologically complex alluvium extending inland from the coastal town of Banda Aceh in Northern Sumatra. Field techniques used successfully were surface mapping, machine boring, hand augering and Dutch cone penetrometer sounding; resistivity results were, however, difficult to interpret. Field and laboratory data were recorded on coding forms providing a consistency of data quality and allowing the creation of a computer data bank. This was used to aid interpretation and to assist in the development of units of like geotechnical characteristic which form the basis of the engineering geological maps and sections. The difficulties encountered in doing this are discussed. It is concluded that this regional mapping approach is a useful first step in providing data for planning decisions but that it is not feasible to come to a full understanding of such a complex lithology in mapping an area of this size.
