Hence, the project Urban Flood Resilience- Smart Tools (FloReST) was initiated by six partners from the field of civil engineering, informatics and hydrology to research on tools for high-resolution drain path identification and risk mapping. In this context, a mobile application shall be developed for crowdsourced data collection in civil society. Still being in the early stages of development, a first requirement catalogue for the application is presented and discussed, showing that especially data control is a problematic issue in Citizen Science.enCitizen Sciencemobile application developmentcrowdsourced data collectionflood risk managementpluvial floodingsurface runoffdrain pathSmart Citizen Science in pluvial flood disaster risk reduction: Building a Smart Application as one tool for local drain path identification (Work in progress)Text/Conference Paper1617-5468
