Flooding and saltwater intrusion are growing challenges in the Mekong Delta, particularly in Hau Giang Province. Seasonal flooding combined with irregular high tides and rising sea levels causes water levels to fluctuate unpredictably, leading to residential flooding and damage to daily living environments. During the dry season, saltwater intrusion threatens freshwater storage in tanks, ponds and household systems. Manual monitoring is time-consuming, inaccurate and ineffective under rapidly changing conditions. A team of students developed this automated system to help communities protect freshwater sources, reduce flood risks and respond promptly to environmental changes.
HOW DOES IT WORK?
Water level sensors continuously measure the height of water in tanks, ponds or drainage areas and send data to a central microcontroller. The controller compares incoming data with pre-set safe thresholds and, when water rises above or drops below these limits, automatically activates pumps or drainage valves to regulate the water level. By maintaining water within a safe range, the system helps prevent flooding during high tides and reduces the risk of saltwater entering freshwater storage. An integrated IoT module (ESP32) uploads data to a web or mobile application, allowing users to monitor water levels remotely and receive timely alerts. This automated approach ensures continuous protection, faster response times and improved water management for households and flood-prone communities.
