This study proposes a sustainable watershed management framework for supporting decision making. The framework consists of three stages, including formation of visions, development of action plans to implement vision, and improvement of basin assimilation capacity. The decision support tools are developed for each stage to provide important analyses and suggestions to policy making. This research applies Analytic Network Process (ANP) to determine visions for basin development. A dynamic modification method is also proposed to make sure that policy making on sustainability is proper. Action plans to implement vision includes developing an optimization model to maximize assimilation capacity and to allocate the capacity with considering equity. The Gini coefficient is used in evaluating the equality of waste load allocation. Data Envelopment Analysis (DEA) considering in assimilation capacity and equity is applied to estimate the efficiency of different zoning rules in basin. To improve basin assimilation capacity and equity, an optimization model combining Simulated Annealing Algorithm (SA) with DEA is formulated to determine the best locations of point pollutant discharges. The TouChen River is taken as a study site to explain the procedures of decision support tools in each sustainable management stage.
