Geotechnologies and increased accuracy in original and anthropogenic morphologies mapping applied to flood risk assessment

Abstract

This paper presents new developments on cartographic methodologies to investigate the impact of urbanization on fluvial systems exploring new advances on geotechnologies. The analysis performed with high resolution data highlights the increase in surface connectivity due to urban structures, altering flood dynamics. Key findings include new possibilities for original fluvial plain restitution and mapping, identification of flood spread areas restriction due to the presence of buildings and the narrowing of floodplains. The results underscore the need for integrating geomorphological insights in urban planning to mitigate flood risks and preserve floodplain storage capacity.
