Overview

Randomized trial evaluates water quality impact from dams on adjacent rivers, suggesting significant ecological effects.

Key Points

  • This research aims to assess how dam constructions affect the water quality of adjacent rivers and streams.
  • Integrated long-term water quality monitoring data with Partial Least Squares Discriminant Analysis (PLS-DA).
  • Studied fourteen major Bulgarian reservoirs with sampling locations upstream and downstream.
  • Analyzed physicochemical parameters and potential toxic elements from collected data.
  • Identified clear upstream dominance in water quality for Pchelina, Saedinenie, and Ticha reservoirs.
  • Observed strong downstream impact patterns for Dospat and Yovkovtsi reservoirs.
  • Classified water quality parameters into three clusters based on their functional behaviors.
