Through systematic analysis over the background, theories, framework and modeling approach of river water quality model no. 1(RWQM1), it is believed that RWQM1 has a great adjustment on the current water quality model from the aspects of technology level and modeling method, providing a new standard for future water quality modeling. As the scientific standard for future water quality modeling, the standardized design routine of RWQM1 includes: (1) defining a wide range water quality variables and standardizing the terminology of these variables; (2) providing stoichiometric formulas with strictly mass balance among water quality variables; (3) using Peterson matrix among water quality processes to structuralize water quality models. The structuralized routine makes RWQM1 model flexible and applicable. However, problems including the complexity of variables and processes and lacking software platforms powerful enough for RWQM1 potentially limited its further popularization.
