ABSTRACT

River Type Hydropower Plants (HPPs) which set on main stream in one watershed may affect water quality parameters and aquatic ecosystems. Owing to the geographical and ecological features, Northeast of Turkey has high potential of the hydropower energy.

In this study, we determined monthly some water quality parameters by using YSI Professional Plus instrument for one year in two hydropower plants (Çamlıkaya HPP and Arca HPP) constructed on Solaklı River in Trabzon province, Turkey. Temperature (°C), pH, electrical conductivity (mS cm-1), dissolved oxygen (ppm) and total suspended solids (TTS, mg l-1) were measured at the samples points. Results demostrated that the quality and quantity of water in the main stream were negatively affected by HEPPs in both operational and constructional phases. Statistically, significant changes were occured in water quality parameters such as TSS, pH and temperature. It was concluded that these negative changes were caused by the sand mine in constraction phase of HEPPs. Furthermore, aquatic ecosystems and riperian zone may negatively affected by the decrease of the amount of water released into the river during the operational phase of HEPPs
