It is very important to accurately predict the river water quality. Prediction of river water quality has beenclosely watched in water resources evaluation, and is the primary work of scientific planning and managementof water resources and exploitation. The accuracy of prediction will directly influence whether we can workout a reasonable plan and management measures. According to the relationship of river water quality withthe influencing factors, regression method is used to predict the tendency of river water quality. The influencingfactors include rainfall, sediment and runoff. This study could provide reference and guidance for furtherexploitation of river water..
