Introduction: This paper examines the transformative role of drone technology in water sciences, focusing on its applications in hydrology, water quality assessment, and aquatic ecosystem monitoring. With the growing need for high-resolution, spatially comprehensive data in water sciences, drones offer an unprecedented opportunity to enhance data collection and analysis. Methods: We review current methodologies, including drone-based remote sensing, water sampling, and thermal imaging techniques, to assess water bodies and their surrounding environments. Results: Findings highlight the efficiency of drones in capturing detailed, real-time data on water quality parameters, surface water movements, and vegetation health, contributing to more accurate hydrological models and environmental assessments. Conclusions: The incorporation of drone technology in water sciences significantly advances the field, offering more agile, precise, and cost-effective methods for water monitoring and management. This shift not only supports better-informed decision-making but also paves the way for innovative research avenues in understanding and protecting aquatic ecosystems. Future research should focus on developing standardized protocols for drone operations in water sciences and exploring the integration of drone data with traditional monitoring systems for comprehensive watershed management. Moreover, as drone technology continues to evolve, its integration into water sciences promises further enhancements in spatial and temporal data resolution. This progression is crucial for addressing the complex challenges of water management in the face of climate change and increasing human impact on natural water systems.
