A System Approach for the Study and Control of Factors Affecting Water Pollution

摘要

The objectives of the research were directed toward testing the feasibility of applying a system approach for the study of pollutants and/or quality factors in a river. The Pearl River and its major tributaries were selected to implement the study. Preliminary analysis of the Pearl River data suggested treating it by dividing it into reaches. Stepwise multiple regression FORTRAN program was compiled and run under an IBM 360 system for regressing the quality factors of each reach. The quality characteristics of the surface waters have been mathematically explained. Five sets of regression equations, each describing the qualities of water in one reach during short and dry periods, were obtained. Another two sets of regression equations describing the qualities of water in the river at the city of Bogalusa, Louisiana, one set for the year 1967 and the other for the year 1968, were also obtained. Within limitations imposed by the data, the regression equations can be used for purposes of prediction. (Author)
