Dry season alert accuracy exceeds 95%, false alarms reduced by 80%

Solution Details

Ensuring Ecological Baseflow with Intelligent Monitoring

Ensuring ecological baseflow in rivers and lakes is a core requirement of water resource management and a key performance indicator in China's River Chief System. Northern rivers increasingly face flow interruption and lake shrinkage, demanding real-time intelligent monitoring systems like the River & Lake Ecological Baseflow Monitoring and Early Warning System.

Core Features of the Baseflow Monitoring System

Non-contact Multi-band Doppler Radar Flowmeter: Provides accurate velocity and flow measurement without physical contact, ensuring maintenance-free operation.
Visual Radar Level Meter: Enables 'See the water level' functionality with synchronized water level data and video capture.
Solar + Battery Self-Powered System: Offers reliable, off-grid power for continuous monitoring in remote locations.
Hero V9 RTU with Multi-Link Communication: Aggregates data using 4G, BeiDou, and satellite links for robust connectivity.
Four-Tier Ecological Baseflow Alert System: Triggers Blue, Yellow, Orange, and Red alerts when flow drops below set thresholds.
GIS-Based Watershed Monitoring Dashboard: Provides a comprehensive visual platform for managing watershed data and alerts.

System Architecture and Data Integration

Ecolor Technology's system deploys multi-band Doppler radar flowmeters at critical cross-sections for non-contact velocity and flow measurement, paired with visual radar level meters for synchronized water level and video capture. Hero V9 RTU aggregates this multi-source data for the central management platform.

Measurement Method

Non-Contact Radar

Communication

4G/BeiDou/Satellite

Alert Tiers

Four Levels (Blue to Red)

Proactive Early Warning for Baseflow Management

The integrated platform continuously analyzes the data from field sensors. It triggers tiered alerts when the measured flow drops below pre-defined ecological baseflow thresholds, enabling timely intervention and management actions to protect river and lake ecosystems.

Approach

How we implement intelligence into your infrastructure step by step.

Critical Cross-Section Flow Monitoring

Multi-band Doppler radar flowmeters deployed at assessment cross-sections, using multi-frequency radar for non-contact surface velocity measurement with integrated HD cameras for site documentation.

Water Level & Video Fusion Monitoring

Visual radar level meters at key river points combine 80GHz mmWave radar for precise level measurement with HD cameras for real-time visual verification.

Self-Powered Remote Telemetry

Each station equipped with solar panels and battery banks, Hero V9 RTU collects flow, level, and weather data via 4G/BeiDou dual-link transmission.

Intelligent Baseflow Alert System

Platform automatically compares measured flow against seasonal and reach-specific baseflow thresholds, triggering four-tier alerts pushed to responsible officials.
