Dams are vital infrastructures for water storage, irrigation, flood control, and power generation.However, sudden increasesin waterlevel dueto heavy rainfall can cause severe floodingand loss of life if not monitored and controlled properly.This project presents an IoT-based Dam Management and Disaster Monitoring System that continuously monitors the water level using an ultrasonic sensor (HC-SR04).When the water level exceeds a predefined threshold, alert messages are sent to registered mobile numbers using a GSM/GPRS module, and a buzzer is activatedtoprovide localwarning.Simultaneously,thedamgateis automaticallyopenedusing a DC motor controlled through an L293D motor driver anda rack and pinion mechanism.When the water level decreases toa safe limit, the gate isautomatically closed.Sensor data and system status are displayed on an LCD and uploaded to an IoT cloud platform using GPRS for real-timeremote monitoring.The proposed system enhances dam safety, automation, and disaster prevention with minimal human intervention.
