Nature-Based Solution Integration to Enhance Urban Geomorphological Mapping: A Methodological Approach

This study conducted an extensive literature review spanning from 1950 to 2023, exploring the methodologies in urban geomorphology and urban geoheritage assessment, and the possibility of applying Nature-Based Solutions (NbSs) in order to enhance geomorphological maps. The methodology proposed here is based on a two-step approach: (i) a bibliographic review and methodological investigation and (ii) methodological proposal in order to enhance the traditional geomorphological and geoheritage maps with NbS to reduce the geomorphological risk in urban areas. This paper aims to introduce a methodological framework and illustrated its practical application to provide researchers and practitioners with a clear understanding of its implementation in real-world scenarios. The proposed methodology was applied in the north and northeastern parts of Milan, Italy. The implementation of the proposed methodology demonstrated its effectiveness in urban contexts and its potential for further modification and extension to various urban environments in the future.
