1. Technical Background: Integrated Hydrological Radar System
The ”Three-in-One Hydrological Radar System” typically integrates the following functions:
- Surface Water Monitoring (Open Channels/Rivers): Real-time measurement of flow velocity and water levels using radar-based sensors.
- Underground Pipeline Monitoring: Detection of leaks, blockages, and groundwater levels using ground-penetrating radar (GPR) or acoustic sensors.
- Dam Safety Monitoring: Monitoring dam displacement and seepage pressure via radar interferometry (InSAR) or ground-based radar.
In tropical, flood-prone countries like Indonesia, this system enhances flood forecasting, water resource management, and infrastructure safety.
2. Real-World Applications in Indonesia
Case 1: Jakarta Flood Monitoring System
- Background: Jakarta faces frequent flooding due to overflowing rivers (e.g., Ciliwung River) and aging drainage systems.
- Technology Applied:
- Open Channels: Radar flow meters installed along rivers provide real-time data for flood alerts.
- Underground Pipelines: GPR detects pipe damage, while AI predicts blockage risks.
- Outcome: Early flood warnings improved by 3 hours in the 2024 monsoon season, increasing emergency response efficiency by 40%.
Case 2: Jatiluhur Dam Management (West Java)
- Background: A critical dam for irrigation, hydropower, and flood control.
- Technology Applied:
- Dam Monitoring: InSAR detects millimeter-level deformations; seepage radar identifies abnormal water flow.
- Downstream Coordination: Radar-based water level data automatically adjusts dam discharge gates.
- Outcome: Reduced flood-affected farmland by 30% during the 2023 flood season.
Case 3: Surabaya Smart Drainage Project
- Challenge: Severe urban flooding and saltwater intrusion.
- Solution:
- Integrated Radar System: Sensors monitor flow and sediment buildup in drainage channels and underground pipes.
- Data Visualization: GIS-based dashboards help optimize pump station operations.
3. Advantages and Challenges
Advantages:
✅ Real-Time Monitoring: High-frequency radar updates (minute-level) for sudden hydrological events.
✅ Non-Contact Measurement: Works in muddy or vegetated environments.
✅ Multi-Scale Coverage: Seamless monitoring from surface to subsurface.
Challenges:
⚠️ High Costs: Advanced radar systems require international partnerships.
⚠️ Data Integration: Requires inter-agency coordination (water, municipal, disaster management).
