URban GEodiversity for a Resilient Environment
Geodiversity refers to the variety of natural abiotic features, as the natural variety of geological (rocks, minerals), geomorphological (landforms, physical processes), hydrological and soil properties. The parameter “geomorphodiversity” is a measure of the dynamics of the Earth's surface and it has a key role in conservation of biodiversity and sustainability of ecosystems. Thus, it affects evolution of the biotic world and of human life. ...
Geomorphometric analyses in mountain catchments
Geomorphometry complements the traditional qualitative description of landforms with a quantitative approach based on the analysis of Digital Terrain Models, which are numerical representations of the topography.
For the purpose, geomorphometry develops and exploits new algorithms in GIS (Geographical Information System) environments.
The scope of the analysis is to derive parameters (e.g., terrain slope, surface roughness), or ...
Assessing sediment connectivity and availability in several mountain catchments in the Veneto Region
Mass wasting is a threat to residential areas and infrastructure, causing widespread destabilization in alpine stream channels, also in relation to ongoing climatic changes. Although hillslope sediment supply represents a critical factor for stream channel stability during heavy rainstorms, there is a general lack of procedures for quantifying sediment availability and composition. Moreover, we lack validated empirical models for estimating ...
Methodologies for the analysis of alluvial fans
Some areas mapped in the Piani di Assetto Idrogeologico (Watershed Management Plan) of Piave, Brenta-Bacchiglione and Livenza Rivers require specific studies aimed at assigning a degree of hazard. Among the warning areas, there are numerous alluvial fans. The Soil Conservation Division of Veneto Region, in charge of the inquiry, identified the need to find an objective method for assessing the hazard of such ...
Sediment Connectivity Assessment
SedInConnect is a stand-alone application for the computation of the Sediment Connectivity Index (Cavalli et al., 2013, Crema et al., 2015).
The software has been developed in the frame of the SedAlp project, funded by the Alpine Space Programme (European Territorial Cooperation 2007-2013)
The output of the applied model is a topography-based index aiming at evaluating the potential connection between hillslopes and features acting as targets ...
