IoT-Based River Monitoring System for Real-Time Water Resource Management

Rivers are essential components of water resource systems, supporting flood control, agricultural irrigation, ecological protection, and urban development.

However, many rivers are located in remote areas where traditional manual monitoring methods face challenges such as:

• Limited observation frequency
• Difficult access to monitoring locations
• Delayed detection of water level changes
• Lack of real-time data for decision-making

KEHAO provides an integrated River Hydrological Monitoring Solution based on IoT technology, combining water level sensors, flow measurement equipment, rainfall monitoring devices, RTU data loggers, communication networks, and cloud platforms. The system enables real-time river monitoring, remote data transmission, flood risk analysis, and intelligent water resource management, helping governments, water authorities, and engineering companies build modern digital hydrological monitoring networks.

River Hydrological Monitoring System Architecture

KEHAO River Monitoring System includes:

Hydrological Sensors

• RTU/Data Logger
