REVIEW OF WATER QUALITY ISSUES OF GODAVARI RIVER BASINAND PREDICTION MODELSALKA S. KOTE AND VRUSHALI V. SASANE
Water is an essential element for all living organisms on the earth. The surface water is available in the form of rivers, lakes, ponds etc. and ground water in the form of the aquifer system. The rapid urbanization and industrialization has increased the demand for fresh water, however, the same is responsible for pollution of water resources. This paper reviews experimental evidence of the surface and groundwater quality issues in the Godavari river basin. A rigorous survey was done on the available literature to reveal the reasons for the contamination, assessment methods and mathematical tools applied for prediction. This study also intends to find the applicability and feasibility of tools like artificial neural networks (ANN) and support vector machine (SVM) for prediction modelling of water quality. The review findings showed that the surface and groundwater quality scenario of the Godavari river basin is not good and needs an effective management framework to protect the water quality and water quality prediction tools for successful implementation of the management plan. The tools like ANN and SVM can be effectively used for water quality modelling of Godavari river basin.
