| Abstract | The daily discharge records of Hsintien River were subjected to frequency analysis. For local conditions, the design flow was determined as 11.6 m3/sec for water quality modelling. By the transformation of reaction time to equal travel time, a simple indirect model for DO and BOD balance in a river was developed. With the consideration of mass balance in a river and using the principles of systems analysis, a DYNAMO Model was developed for the DO and BOD distributions in the Hsintien River. Sensitivity analysis was used in testing the influence of parameters such as flow rate, deoxygenation and deoxygenation coefficients. Dissolved oxygen standards for the Hsintien River water quality were recommended as greater than 2 mg/l, equal to or above 2 mg/l, and equal to or above 1 mg/l in the upstream, middlestream, and downstream reaches, respectively. These standards were based on the predominating uses of potable water supply, fishing and waste disposal, respectively. |
