Real-time WSN based early flood detection and control monitoring system

The downstream flooding from dams due to environmental disasters leads to failure of evacuation of nearby staying peoples cause high mortality rates and casualties. It is essential to record the height reached by the water and leak of water through the walls of dams in real time to avoid flooding and thereby casualties. The traditional manual monitoring are discommodious and scattered nowadays. It has also certain shortcomings that includes high cost and poor network connectivity. This paper presents a real time Wireless sensor network based early flood detection and control monitoring system designed with a function of real time monitoring, guaranteeing connectivity in low cost. This system collects data as images from CMOS image sensors through wireless sensor nodes which transmit these images to remote monitoring centre via Zigbee network and GSM network. The remote centre will process the data by analyzing it and give necessary alert to clients. Simulation results show this system is cost effective and reliable for early detection of flood.
