Abstract:Rough set theory is a new approach to decision making in the presence of uncertainty and vagueness. The essential concept of rough set theory is presented in detail and its application in hydrologic forecast is briefly described. The case of forecasting annual runoff of Dahuofang reservoir and its results indicate that rough set theory is effective and easily understood in forecast model.
