ABSTRACT
This chapter discusses the areas of geology of interest to engineers and illustrates how geology contributes to the resolution of civil engineering and environmental problems. Engineering Geology embraces: the definition of the geomorphology, structure, stratigraphy, lithology and groundwater conditions of geological formations; and the assessment of the mechanical and hydrologic behaviour of soil and rock masses. The chapter examines the ancient origin of Earth science as early man tried to answer questions raised by his observation of the land. Beyond the scientific basis, the study of Earth science influences the way an engineer thinks, both in the exercise of his profession and in his culture. The geologist collaborates with the geotechnical engineer to determine if a piece of land proposed for construction has the necessary stability conditions. The distribution of tasks between the geologist and geotechnical engineer varies from country to country.
