AB: The stream assimilative capacity is the carrying capacity of a river for the maximum waste load without exceeding the water quality standard. However, only optimizing maximal waste loads may lead to inequity. Equity is an important issue in waste load allocation problems. This research formulates a multi-objective model that considers minimizing inequity and maximizing total waste loads by using water quality models, as well as combining Gini coefficient and Data Envelopment Analysis (DEA) to assess the relationship between the equity levels and the maximum waste load. It is also discussed that the impacts of changes in the land use among up- stream and down-stream on assimilative capacity and equity, which can provide useful information for the policy making of sustainable watershed management.
