Web-messaging-based dissemination of urban rainfall and flood information: a Telegram bot framework
摘要
Cities serve as major economic centers and experience significant socio-economic impacts from urban flooding, necessitating user-friendly decision-support tools. This study presents an R-based automated, web-messaging-based quasi-operational near real-time framework for rainfall and flood information dissemination. The framework integrates automated data acquisition and develops rainfall and consequence-specific flood risk maps using a probabilistic hazard-vulnerability approach; offering a scalable tool in resource-constrained cities, with potential extension to finer temporal scales.
