The publication contains the papers presented at the 'Seminar on the Engineer and the Environment', presented by the Department of Conferences and Institutes of the General Extension Division of the University of Minnesota. The seminar was planned in cooperation with the Northwest Section of the American Society of Civil Engineers. The purpose of the seminar was to inform engineers of current environmental issues, with particular emphasis being placed on water resources problems. The planning for the conference was based on the premise that the engineering profession should be aware that environmental issures are of paramount concern to society and that the profession is responsible for giving full consideration to these issues in addition to fulfilling the traditional role of solving purely technical problems. The subjects of the papers are: An Ecological Approach to Natural Resource Problems; Drainage and the Environment; Environmental Aspects of Water Resources Planning and Development; Social Aspects of Ecology; The State Concern in Engineering Planning for Water Resources; and The Challenge of Environmental Concerns in the Future of Engineering.
