Review of River Water Quality Modeling Software Tools

River water quality has generally declined due to many human activities. In order to prevent or to control the degradation of river water quality, an appropriate management strategies must be considered. To manage river water quality in the most effective and efficient way, the cause and effect relationship of the river system must be identified. This can be done with a river water quality modelling tool. Many of these modelling tools are generic and are available in the public domain at no cost. However, it is necessary to review available river water quality software modelling tools, so that the most appropriate tool can be selected for the specific application. This paper will concentrate on the review of river water quality modelling tool. Then a case study on the selection of a suitable tool for the development of a river water quality model for Yarra River, Australia will be discussed. Based on the investigation, QUAL2E was identified as the most suitable software for the development of a Yarra River water quality model
