Potential arrangements for water quality-quantity management institutions to meet future needs are examined. Part 1 describes specifications for water quality and integrating water quality - quantity planning. Part 2 proposes factors (25) for evaluating water management institutions; traces the history and describes nine types of institutions; examines eight case studies. Conclusions show that institutional development has grown slowly out of the nations experience; and suggest the beginning of a focus on selected institutions. Part 3 describes the Hudson River Basin, examines attempts at management institution designs, presents papers clarifying Hudson Basin problems, and concludes with no specific organizational plan but rather ideas to help reach a useful decision. Part 4 propses synoptic and incremental water resources planning processes as the methods of choice, reviews the ideas used to strengthen the Corps of Engineers role in water quality planning, and assesses the value of ideas developed by this research project in relation to the Federal Water Pollution Control Act.
