Abstract:
Water bodies all over the globe are contending with a severe issue of deterioration, which has the risk to have huge impacts on the ecosystem, society, and economy. Carlson's TSI (Trophic State Index) has been used in the Tiru reservoir to analyze its eutrophication level from August 2017 to January 2019. TSI (Secchi Disk Depth) was highest in June 2018, TSI (Chlorophyll-a) was highest in April and May (61), and TSI (Total Phosphrous) was highest in May 2018 (59). October 2017 had the lowest TSI (Secchi Disk Depth) = 64, TSI(Chlorophyll-a) = 42, and TSI (Total Phosphorus) = 35 values. Throughout the study, Tiru reservoir was eutrophic. The Tiru reservoir's water quality fluctuations were mostly caused by changing weather patterns during the research. Eutrophication in the Tiru reservoir was caused by less frequent monsoons, agricultural runoff, and monsoon sediment inflow.
