Abstract
A study on the seasonal variation of quality of River Godavari waters at Polavaram in Andhra Pradesh is made using different multivariate statistical methods. The water quality indices (WQIs) are computed using WAIWQI and NSFWQI methods. The data obtained from the Central Water Commission, Hyderabad, Andhra Pradesh, for a period of decade, i.e. 2002–2012, is taken into consideration for conducting the study. Twelve parameters are being considered for analysis related to water suitability for irrigation purposes. Using this analysis, the principal parameters affecting the quality of water during the study period are obtained. The cluster analysis (CA) conducted on temporal basis displayed clusters of the years based on their similarity. When this cluster analysis is compared with the water quality indices determined using WAIWQI and NSFWQI methods, it is found that the clusters vis-à-vis the WQIs are in good correlation. From the results obtained, it is concluded that the quality of water in River Godavari at Polavaram is found to be suitable for irrigation purposes.
