INTEGRATED EVALUATION MODEL FOR SURFACE WATER QUALITY A CASE STUDY IN HO CHI MINH CITY, VIETNAM
The quality of water is a measure of a number of characteristics that impact on its condition. Parameters affecting the water quality are classified as having chemical, physical, biological and radiation characteristics. However there is uncertainty as to whether or not a water sample meets set standards in quality if two or more parameters need to be considered. Therefore, this study is to develop an effective evaluation model, adopting fuzzy logic, to assess the quality of water. Using a case study in Ho Chi Minh, Vietnam, a model has been developed and applied the collected surface water monitoring data in 2015. The results obtained from this model are then compared to the results gained from Vietnam national water quality index established in 2011.
