The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. The current study aims to conduct a comprehensive analysis of the key parameters that affect the energy output of the Bagisli Hydropower Plant, located on the Zap River in the Dicle (Tigris) basin of Turkey. It considers the daily data for the time interval of 2016–2019 related to flow rate, precipitation, and temperature in relation to the generation of electricity. The relationship between energy output and flow rate is evident; however, the energy production is limited by the design flow rate. The present study undertook a thorough examination of the important factors that influence the energy generation of a selected hydroelectric facility, known as the Bagisli Hydropower Plant, which is situated on the Zap River within the Dicle basin in Turkey, considering the daily data for the time interval of 2016–2019 related to flow rate, precipitation, and temperature in relation to the generation of electricity.
