Level-B Multiobjective Planning for Water and Land

The models represent economic development and environmental quality related to water quality and land use planning, and are formulated in a multiobjective optimization framework. The economic objectives constitute the cost of point and nonpoint-source pollution abatement, and other related land activities. The environmental quality sector includes the following noncommensurable objectives: (1)Soil erosion and sediment control; (2)control of phosphorus discharge from point and nonpoint sources; (3)abatement of biological oxygen-demanding material from point sources; (4)enhancement of land-based recreational opportunities; (5)maintenance of wildlife habitat; and (6)flood control. The trade-offs analysis was carried out using the Surrogate Worth Trade-off (SWT) method. The planning framework was developed for the Maumee River Basin Level-B Study. A recommended plan with its associated trade-off values are presented. The decision-maker's (Planning Board) role in obtaining a basin-wide plan is discussed.
