Comparison of eutrophication level by applying different trophic state indices to the Tiru reservoir, Udgir, dist. Latur

Abstract

Freshwater resources are limited in nature and their demand is increasing daily. The use of excessive chemicals and fertilizers increases water fertility. Eutrophication is a common problem all over the world. To conserve these resources, they should be appropriately monitored to know their trophic condition. Various researchers have proposed different water classification criteria and methods. The present study attempted to apply multiple trophic status indicators to the Tiru reservoir water quality characteristics. Water quality data were gathered from the Tiru reservoir, Udgir Tahsil, Latur (Maharashtra) between February 2018 and January 2019. Markad et al. (2019) established the TSI model based on the native biological and geographical conditions, which resulted in optimal performance for measuring the trophic state of the Tiru reservoir.
