Dam Water Discharge and Flood Prediction Cum Warning System

Abstract

To create an autonomous system that warns people during discharge of dam water predicts the possibility of a flood (based on weather forecast) due to overload of water in a dam’s reservoir and warns people in advance. The system uses a NodeMcu module to read data from water level sensors placed in the reservoir of a dam. Change in water level is indicated to a sensor cloud (Ubidots). A website uses this data along with a weather forecast for that area from Yahoo! Weather API to predict the possibility of a flood over a week’s time frame. This website can be used by tourists to plan their trips to the dam. Discharge of water from the dam is detected by a proximity sensor placed in the control gate of the dam which is also connected to the NodeMcu module. When the proximity sensor comes on, it triggers a series of LED lights and buzzers placed along the discharge area of the dam to alert locals about the discharge of water from the dam. The system sends a warning SMS to people living near the dam when the water level in the dam reaches the critical limit. The system triggers the local warning system as and when the control gate is opened in the prototype. Water level changes are intimated to the sensor cloud and a warning SMS is sent when water reaches the critical level in the reservoir of the dam. Under this condition, if the control gate is also opened, an emergency SMS is sent asking people to evacuate immediately. This system can help save the lives of people living near dams by warning them well before the occurrence of a flood.KeywordsWi-FiCloudDam warning systemWeather
