Summary For effective ambience water quality control, it is relevant to establish master plans on pollution loads in units of watersheds. In practice of plan formulation, estimation of pollution loads on a watershed basis accompanies not a little time and works of data collection and calculation. This research aims to establish database for pollution loads and seek for a methodology of estimating pollution load accurately and in a more reasonable way.
