The present state of the art of dam engineering has been ronmental, and political factors, which, though important, attained by a continuous search for new ideas and methods are covered in other publications. while incorporating the lessons of the past. In the last 20 The rapid progress in recent times has resulted from the years particularly there have been major innovations, due combined efforts of engineers and associated scientists, as largely to a concerted effort to blend the best of theory and exemplified by the authorities who have contributed to this practice.

One of the synthesis volumes of the Decade of North American Geology Project (celebrating the 100th anniversary of the GSA). It covers the history and development of engineering geology, engineering works relating to geological processes, construction materials and the environs of works, geological

Contains papers presented at the Specialty Conference sponsored by the Geotechnical Engineering Division of American Society of Civil Engineers held in North Carolina, 1993. This proceedings covers topics such as: inspection and monitoring of dams; investigation and evaluation of dams and foundations; risk and reliability assessment; and others.
