IoT-Based Flood Management: Leveraging Data for Safety and Preparedness

Flooding is a frequent natural disaster in many regions of Indonesia, causing physical damage, endangering lives, disrupting economic activity, and impacting the environment. Effective flood management is essential, and recent technological advances have made IoT-based systems a leading solution. IoT technology enables real-time data collection and analysis, which strengthens both government and community preparedness for potential floods.

IoT-based flood management uses IoT devices to monitor, detect, and analyze flood-related data. By gathering real-time information through these sensors, authorities gain precise insights into water levels, rainfall, soil moisture, and water flow speed. This information becomes critical for flood risk prediction, enabling communities and governments to take preventive actions and respond more effectively.

Benefits of IoT Technology in Flood Management

There are numerous benefits of integrating IoT technology into flood management, such as:

• Real-Time Monitoring: With sensor data, authorities can track water levels and weather conditions as they change.
• Early Detection: By providing accurate information, the system allows early flood risk detection, giving communities more time to take action.
• Weather Prediction: Algorithms and models built on IoT data help improve weather forecasting accuracy.
• Fast Communication: Emergency response teams receive data instantly, ensuring that their efforts are well-coordinated.

1. Water Level Sensors

Authorities install these sensors in rivers, dams, and other water channels to monitor water levels. If water rises beyond safe limits, the system immediately alerts local authorities.

2. Rainfall Sensors

Rainfall sensors monitor the intensity of rainfall in a specific area. When rain levels become dangerous, the system quickly informs authorities and the public, raising awareness and preparedness.

3. Soil Moisture Sensors

Soil moisture is a key factor for gauging how well the ground can absorb rainwater. Since saturated soil increases flood risk, these sensors provide timely data on soil absorption capacity.

4. Use of Drones and CCTV Cameras

Drones and CCTV cameras enable aerial monitoring of flood-prone areas. They support emergency response teams in assessing field conditions, which helps in choosing safe evacuation routes.

5. IoT Platforms and Cloud Computing

Data from various sensors is sent to an IoT platform that utilizes cloud computing. This platform analyzes and stores data, which is then used for real-time monitoring and long-term flood risk assessment.

IoT-Based Flood Management Implementation in Various Regions

Case Study: Semarang City

Semarang, which often experiences severe flooding due to high rainfall and vulnerable geography, has adopted IoT-based flood management. The city has installed sensors in flood-prone areas, and data from these devices integrates into an app accessible to monitoring teams and the public. This app provides timely information on potential flooding, improving overall preparedness.

Case Study: Jakarta

In Jakarta, IoT technology is also used for flood monitoring, particularly along major rivers. With sensors monitoring water levels and rainfall, the flood control center receives real-time data, enabling the government to issue early warnings to residents in high-risk areas.
