Spatio‐Temporal Variations in Water Quality of Muttukadu Backwaters, Tamilnadu, India

Abstract: Muttukadu Backwater, located on the east coast of Tamilnadu, is one of healthiest estuarine environments in the region. A study pertaining to seasonal variations in physico-chemical properties in water was conducted at nine sites of Muttukadu Backwater for a period of one year (January to December 2009). Multivariate statistical techniques, such as cluster analysis and principal component analysis (PCA), were applied to evaluate the variation in water quality of Muttukadu Backwater and to identify pollution so… Show more

“…As far as the dissolved oxygen of the Batticaloa Lagoon is concerned, the present study revealed that there was a significant negative correlation found (Table 2) with salinity (r= -0.186**), temperature (r=-0.256**) and TSS (r=-0.594**). Srinivasan and Natesan (2013) also found similar results in Muttukadu Backwaters in Tamilnadu.…”

“…The highest salinity and electrical conductivity values found at station probably due to the shallowest depth of this station and to the low rate of water renewal in this site which is very fare from the inlet (Aknaf et al, 2017). Salinity was at a maximum (34.6 ppt) during monsoon season because of the opening of the mouth (Srinivasan & Natesan, 2013). Salinity was the lowest of 30.31 at ST4 because there was minimum interaction of the sea with the estuary, as the depth observed the lowest of 2.0 m, compare to 5.0 m at ST 2.…”

“…The high pH value (8.46) is due to the algae growth during that period, increasing the consumption of CO 2 as part the photosynthesis process and consequently driving up the pH (Aknaf et al, 2017), but in this study no relationship was observed between the fluctuation of pH with the production of cell density. The extensive buffering capacity of the seawater with the tidal fluctuation may be the cause for a change in pH within a very narrow limit (Srinivasan & Natesan, 2013). Significant differences in monthly fluctuation in salinity were observed in the Kudat Coastal water.…”

“…Then, spatial zones had to be managed. Another study by [59] used PCA and CA to identify the variation of water quality and identify the pollution sources in Muttukadu Backwater and further analyze water quality using the interpolation method in ArcGIS software. In a study by [60], the PCA was used to find the structure in the relationships between variables which were then entered into the logistic model for predictive model fitting.…”
