Design and Implementation of an IoT-Edge Computing-based Flood Monitoring System for Early Warning: A Case of Nagaon District in Assam

A flood is a severe disaster affecting people around the globe, and the statistics show India is more vulnerable to floods. With a geographical area of 328.72 mha (million hectares), from which more than 40 mha is prone to flood. Floods commonly result in significant loss of life and destruction of property, infrastructure, and public utilities. As of 2022, during heavy monsoon, the northeastern states have suffered a considerable loss due to floods. Among these, Assam has taken a significant blow from the flood uprooting many homes, taking many lives and affecting people's daily routine. In addition, numerous villages and houses were swept, destroying agricultural fields and leaving people to starve to death. In light of this issue, we, in this paper, aim to design and implement an IoT-based flood monitoring system that can signal a rise in water level, allowing people to make prior management to counter the situation. The implementation results show how the increase in water level is recorded in ThingSpeak, an IoT platform to study the live data streams in the cloud at specified intervals notifying the severity of the flood with graphical evaluations.
