Short summary
This proof-of-concept study presents a prototype Citizen and Community Science app that enables residents to document, classify, and report pluvial flood risks at neighbourhood scale in the Ahr Valley, Germany. Crowdsourced data feed into a Geo Data Warehouse to support municipal analysis and decision-making. Its open-source, scalable design strengthens public awareness and offers potential for global adaptation in urban flood risk management.
