The purpose of this study is to assess current water use forecasting practice in the U.S. Army Corps of Engineers and to recommend those additional approaches which best satisfy current requirements. To accomplish these objectives, this report presents the findings of a three-prong investigation: (1) identification of current needs for improved forecasting approaches in light of the current requirements; (2)review and assessment of current forecasting approaches; and (3) recommendation of the most appropriate forecasting approaches which meet the identified needs and satisfy current requirements. Data were obtained from personal interviews with field planners in 6 districts and 3 divisions, from a questionnaire to 35 districts and 11 divisions, and from the analysis of 27 Corps studies that had forecasted demand.
