| Summary: | The importance of river in the global development of mankind is undeniable since most of the early urban settlements in the history of human civilization were discovered near rivers. This development has resulted in wide spread exploitation of the river in many ways such as industries water supply, transportation purpose, domestic usage and also waste disposal. Understanding the negatives effect in long term an improvement of river management and one of the convenient ways is to manage water using water quality model. In this study, QUAL2E a one dimensional water quality model is proved using finite difference of advection dispersion equation. Since the focus of this study is on mathematical formulation, hydraulic data and river characteristics are taken from Tiung (2003). The result of the mathematical calculation is compared with the validated data obtained from this QUAL2E model. Using assumptions to obtain the value of external source, result are obtained in three different ways which are in linear, quadratic and cubic assumptions. The observation shows that the cubic assumptions is the most accurate among other assumptions since the error is small after comparison with data obtained from Tiung (2003). This study shows how the mathematical formulation is used to obtain the value of element?s concentration required |
