Abstract
ABSTRACT The present work contributes to the process of modernization of traditional geomorphological mapping, a fundamental tool for the assessment of the hazard degree of natural processes for the planning, of works and infrastructures. Starting from a traditional and detailed geomorphological survey and through elaborations in a GIS environment, this paper presents a multiscalar cartography model, characterized by a ‘full coverage’ representation of landforms. These characteristics make it possible to upscale or downscale processes and landforms and to use different information levels created in a hierarchical form. The test site for the experimentation is located on the Adriatic side of central Italy and is represented by a small catchment, about 13 km2 large. All geomorphological features and information have been organized as elements and attributes within digital geomorphological information layers, following structured on a Digital Terrain Model derived from LiDAR; this new product is here proposed also as web-browser version.
Highlights
Geomorphological maps are tools for understanding the physical context of the Earth’s surface and for a long time geomorphological maps have been used to describe geomorphological processes and the spatial distribution of landforms
Archiving, updating, analysing and reproducing geospatial data on the screen and the map has been supported by the use of Geographical Information System (GIS) tools, which allow, through an implementable database of attributes, to collect qualitative and quantitative data and information that cannot be reproduced on the map
The subdivision into hierarchical levels allows a more rational use of the represented geomorphological processes and landforms; a greater detail is fundamental for design purposes, while a lesser detail is more functional for territorial planning studies or hydro-geomorphological risk assessment
Summary
Geomorphological maps are tools for understanding the physical context of the Earth’s surface and for a long time geomorphological maps have been used to describe geomorphological processes and the spatial distribution of landforms. Geomorphological maps are used for territorial and environmental planning activities carried out at various institutional levels, from national to municipal, with particular reference to the assessment, management and mitigation of geomorphological hazards (landslides, floods, erosion, etc.) (Bishop et al, 2012; Dramis et al, 2011a; Hayden, 1986; Smith et al, 2011). They are present in the urban planning activities to support municipality for environmental resources and landscape managing and zoning and they are a preliminary analysis for land management projects and geological risk assessment. In the field of application, many disciplines (engineering, hydrological-hydraulic, agronomic, ecological, etc.) require that a modern geomorphological map must be oriented towards a ‘quantitative’ and descriptive-qualitative use of the forms, deposits and processes represented (Dramis et al, 2011b; Gustavsson et al, 2006; Klimaszewski, 1982, 1990; Ten Cate, 1990)
