ABSTRACT: In an attempt to produce a reliable source of water, the water quality model—QUAL2Kw—was put to through calibration and validation tests. This model was implemented in the river Tungabhadra of India. This worked quite well for the project at hand but showed certain irregularities. Different Quality Management methods exist currently and for this project, their impact in DO concentrations were examined based on: 1) The ability to augment the flow; 2) The ability to oxygenate the source and; 3) The ability to modify pollution loads. With the impacts realized, the study helped us understand that local oxygenation is effective when considering the increment of Do levels. There was also the understanding that a combination of the factors (flow augmentation, pollution load modification and source oxygenation) is a necessity as far as the minimum DO concentrations must be realized. With this quality model results, there is confidence that the implementation of the QUAL2Kw model will be an appropriate choice for future river water quality policies.
