Saudi Imam Abdulrahman Bin Faisal University department of computer Science and Saudi Aramco Cybersecurity chair, published in MDPI a study for a solution for Smart Flood Detection to save lives using the integration of AI (Artificial Intelligence), Blockchain and drones. According to the study, floods pose a serious risk and require immediate management and strategies for optimal response times. The Saudi city of Mecca has been impacted by climate change in the last decade as floods have increased despite the city’s location in the Arabian Gulf, which has a hot and wet climate.

Mecca experienced torrential rains on 23 December 2022, at least partly because of its location, surrounded by mountains, causing numerous vehicles to be swept away. The authors propose a secure method of flood detection in Saudi Arabia using a Flood Detection Secure System (FDSS) base
