Water Quality Analysis of River Tungabhadra Near Harihar

Abstract

River Tungabhadra flowing near Harihar taluk in Karnataka (India), receives waste water discharges from villages located on the bank of River and waste water discharged from industries located in Harihar. The present study involves the implementation of QUAL2KW model to determine the water quality status of this polluted our selected stretch of River.

The River samples are collected for pre monsoon and lab results are used for calibrating the model. We observed that predicted values of the model are approximately in match with the observed values. Model results for pre-monsoon indicate decreasing quality of water from upstream to downstream for the selected segment.

Conclusion

From the seasonal investigation it is revealed that at station S1 the water quality index ranged from 54.88 to 69 33 In station S2 69.33.In station S2 it varied between between 70.68 and 70.75 and station S3 it varied between between 64.96 and 112.32 in different seasons of the year.During the study, it is observed that the water quality at station S 3 the water quality at station S 3 is comparatively more disturbed than at station station S 1 . This may be due to the release release of domestic sewage, waste from bank side factories factories and surface surface run-off in to the river system.
