Civil engineers need to know as much as possible about the ground beneath their construction sites before carrying out any civil engineering design works. This book provides a comprehensive coverage of the basic aspects of geology for civil and environmental engineering students so that they are able to adequately recognise, interpret and use geological data in the planning, design and monitoring of civil engineering works. The author uses a direct approach of presenting facts but engages the attention of readers with plentiful illustrations so that they are able to get a feel of the geological aspects even while not being directly situated in the environs being
discussed. Environmental issues, hazards mitigation and resources engineering in the geological context are highlighted in the book. Case studies of failure of civil works due to ignorance of or inadequate attention to the implications of geological aspects provide interesting insights on the relevance of the subject.

The book meets the curriculum requirements of an undergraduate program in civil engineering.

Vasudev Kanithi, a field geologist, is at present a lecturer at the Department of Civil and Environmental Engineering, University of the West Indies. Earlier, he taught at Andhra University, India, and the University of Asmara, Eritrea. His PhD work was on coastal processes and he has presented his research findings in several conferences and journals. He has been an independent consultant for several private, public and government projects in the assessment of groundwater potential, especially in hard rock terrains for wells and borewells for domestic, irrigational and industrial purposes. His interests include groundwater exploration, coastal zone management, slope failures and environmental geology.
