Role of IoT in Flash Flood Monitoring and Early Warning System

The United Nation highlighted a remarkable agenda to reduce the danger of natural disasters. It is to make the environment safe for everyone. The United Nations also acknowledged this need through the Sustainability Development Goals (SDG 11, SDG 15 & SDG 9) to reduce the impact and effect of natural disasters & sustainable disaster management & infrastructure development. Previous studies gave the solution of Data Transmission, analysis and Long-Range Network Protocol usage and the usage of IoT 3Layer Architecture but they didn't emphasize how to overcome with some serious problems as; latency and data transmission to far areas which can't be covered by various networking protocols. The current study indicates the use of IOT 5-layer architecture and its benefits in Data analysis and prediction making and reduces the latency. This paper also addressed the use of the cloud hub to transmit the warning message to the far places. On the foundation of analysis, the paper indicates the lacks and some suggestions for future works. In early Warning System in Flash Flood Monitoring, 5-layer architecture, Cloud Hub LoRa range increasing are some vital suggestions in the study. (Abstract)
