The utilized data set include chlorophyll-a concentrations as an indicator of primary productivity as well as several other water quality variables such as alkalinity, PO4 phosphorus, water temperature and dissolved oxygen concentrations as independent environmental variables. Using the conventional model criteria of correlation coefficient and mean square errors, the fuzzy logic model performed the best with the neural network model better than multiple linear regression model.eninfo:eu-repo/semantics/closedAccessMultiple linear regression modelfuzzy logic modelneural network modeldam reservoir managementeutrophicationArticle316578WOS:0004200820000030
