Research on reservoir water quality prediction based on grey model

Abstract

Combining the gray model to predict the water quality of Qingshan Reservoir,the analysis results show that the grey model has good applicability for the prediction of reservoir water quality. The prediction errors of total nitrogen, total phosphorus, COD5, and ammonia nitrogen are all within 30%, meeting the accuracy requirements of water quality prediction. The research results have important method reference value for reservoir water quality prediction.
