# A Real-Time Water Level and Discharge Monitoring Station: A Case Study of the Sakarya River
## 5 Conclusions  
In this study, a real-time river monitoring station was designed and implemented to provide continuous monitoring of river water levels, offering a reliable and energy-independent solution for environmental monitoring. The system's capabilities were validated through comprehensive calibration and testing, ensuring its accuracy and effectiveness in real-world applications.  
* The real-time river monitoring station provides a robust and sustainable solution for continuous river level monitoring, integrating solar-powered energy independence and advanced IoT communication technologies.  
* Calibration and validation studies conducted in both laboratory and field environments confirmed the sensor's high measurement accuracy, with error margins within 0.1%, ensuring reliability for long-term monitoring applications.
* Validation against upstream hydropower plant (HPP) data demonstrated high correlation (r2 = 0.92) and confirmed the accuracy of the system's measurements in real-world conditions. This high degree of consistency between the station and HPP data reinforces the station's reliability in monitoring river water levels and discharge.
* The system's capability to operate autonomously for up to one week without solar input highlights its resilience and adaptability to remote or poorly infrastructured locations.
* Real-time data sharing and accessibility through an open-access web interface allow users to monitor, download, and analyze measurements in various formats, supporting effective water resource management and flood prevention.
* The early warning system, triggered by ultrasonic sensor readings, provides timely alerts to relevant authorities, significantly enhancing flood risk management and disaster preparedness efforts.
* Minimal data loss during operation has been mitigated through optimized measurement intervals, with future enhancements planned to integrate artificial intelligence and statistical methods for even greater data reliability.
* The system's flexible design allows for scalability and adaptation to various geographic and climatic conditions, making it a model for similar environmental monitoring projects worldwide.
* By addressing the limitations of existing methods, the system offers a practical and innovative tool for advancing flood risk management, water resource planning, and environmental sustainability.  
Overall, the results of this study demonstrate that the real-time river monitoring station is an effective and adaptable solution for environmental monitoring. Its successful implementation and validation underline its potential to contribute to water resource management, disaster risk reduction, and sustainability efforts on a global scale.
