Wineman David C. Major Meta Systems Inc. Graduate School of Geography, Clark University The selection criteria, design, and data for use in a water resources forecasting model for a state (Massachusetts) in which modeling techniques have not been used for water resource planning on a large scale are described. The recommended model, a requirements forecasting model based on employment and population growth, was selected to meet criteria of: compatibility between data availability and the requirements of the model; ease of understanding and use; compatibility with existing planning systems; usefulness at various levels of planning; and flexibility for further development and integration with other models. It can be viewed as the first step toward the development of an integrated long-term water resources planning system for a state. D. C. Major and R. L.
