Powerdrive Technologies, in partnership with the Ministry of Irrigation, Sri Lanka, has successfully implemented an advanced Hydrological Information System (HIS) for the Kelani River Basin. This cutting-edge system is designed to automatically monitor and manage critical hydrological data, such as rainfall and water levels, in real-time, ensuring more efficient and accurate data analysis. The project plays a vital role in supporting proactive water resource management and effective flood control measures in Sri Lanka.
The Hydrological Information System integrates a robust network of terminal stations, each equipped with advanced monitoring sensors. These stations collect data from multiple observation points throughout the basin, transmitting it to a centralized data processing hub for real-time analysis. The automation of data collection and processing significantly enhances decision-making capabilities for irrigation and flood management authorities, providing them with the tools to respond swiftly to potential challenges.
Seamless Data Collection and Analysis
At the heart of the system is a centralized Data Acquisition and Processing System that seamlessly interacts with remote terminal stations across the Kelani River Basin. Utilizing state-of-the-art equipment like the CR800 dataloggers and sensors from industry leaders such as Campbell Scientific Inc. and Nippon Electric Instrument, Inc., the system continuously monitors water levels and rainfall. With SQL Server as its database engine, the HIS ensures smooth and efficient real-time data management, enabling operators to visualize crucial hydrological information through an intuitive Graphical User Interface (GUI).
Key Features : Reliability and Precision
The system boasts several key features designed to ensure high reliability and accuracy in hydrological data monitoring:
- Automated Data Acquisition : The system automatically collects and transmits data to the central server every hour, while also allowing manual re-acquisition of data in the event of communication failures.
- Data Screening and Validation : A robust data validation module ensures that erroneous readings are flagged and corrected, preserving both raw and validated data for future audits.
- Real-Time Reporting : The HIS generates a range of standard reports, including daily, monthly, and hourly updates, offering comprehensive insights into the basin’s hydrological status.
Advanced Equipment Integration
Powerdrive Technologies deployed cutting-edge monitoring equipment to ensure precision in data collection, including:
- Campbell Scientific Inc.: CR800 Data Loggers, CS440-L Pressure Transducers, and CR800 & CR850 Rain Gauges provide accurate measurements of rainfall and water levels.
- Nippon Electric Instrument, Inc.: HM-700 Pressure Probes and N-68 Tipping Bucket Rain Gauges deliver reliable level measurements in various water conditions.
- T&D Corporation: WDR 7 Data Loggers ensure real-time data logging with exceptional precision.
Impact on Water Resource Management
This advanced Hydrological Information System has transformed water resource management for the Government of Sri Lanka, providing real-time, actionable data that supports:
- Flood Management: Authorities can now predict potential flooding events and take preventive actions, safeguarding lives and property.
- Water Resource Optimization: Accurate water level measurements enable informed decisions on water allocation, promoting efficient use in agriculture and other critical sectors.
- Disaster Preparedness: The system bolsters Sri Lanka’s ability to respond to natural disasters by offering early warnings based on real-time data.
