ABSTRACT

Hydropower continues to be a substantial and environmentally friendly source of electricity, with its effectiveness closely tied to the changes in flowrate. This study examines the patterns in flowrate and their influence on power generation, utilising thorough analyses of time, velocity, area, and computed flowrate values. The recorded data covers the time period from May-23 to Oct-23, uncovering clear patterns in the dynamics of flowrate. The findings suggest an initial increase in the rate of flow from May to June, followed by a consistent downward trend in the following months. The interaction among time, velocity, and a consistent cross-sectional area contributes to these fluctuations. Comprehending these patterns is essential for maximising hydropower operations, forecasting ecological consequences, and evaluating system effectiveness. The study proposes the implementation of continuous flowrate monitoring, improvements in operational efficiency, the adoption of adaptive strategies to account for variable flow conditions, technological upgrades, comprehensive environmental impact assessments, research and development efforts, collaborative knowledge sharing, and community engagement as essential measures for achieving sustainable hydropower development. By implementing these recommendations together, the hydropower systems can operate in a resilient and efficient manner. This will contribute to the sustainable use of renewable energy resources and minimise any negative effects on the environment.
