Limnological Review, 2017 Intensive and expansive human activity greatly accelerates the natural process of lake evolution. It is assumed that an increase in the rate of lake fertilization (often termed “eutrophication”) is the most common and most serious anthropogenic ...

<b>Preliminary analysis on the use of Trophic State Indexes in a brazilian semiarid reservoir [PDF]
Acta Scientiarum. Biological Sciences, 2015 The Carlson’s (1977) Trophic State Index (TSI) is a widely employed tool to estimate the degree of eutrophication in a reservoir. In Brazil, the need of a classification system that would take into account regional characteristics employed adjusted indexes generated by data from reservoirs in the southeastern region of the country.

Trophic assessment of streams in Uruguay: A Trophic State Index for Benthic Invertebrates (TSI-BI)
Ecological Indicators, 2011 Abstract Human activities are radically changing natural land cover and increasing the delivery of soil, organic compounds, nutrients, toxic agrochemicals and other contaminants to aquatic ecosystems. The eutrophication of streams, rivers, lakes, reservoirs and costal zones is one of the most important consequences of human activities.

The Trophic Condition of Lake Tana, Ethiopia
Blue Nile Journal of Agricultural Research, 2021 The trophic condition of Lake Tana was studied from 2017 to 2018. Eleven sites were chosen in total, nine on the shores and mouths of important rivers and the other two on the open water of Lake Tana during both the dry and wet seasons.
