INTRODUCTION MORPHOTECTONIC MAP OF THE OSENTO RIVER BASIN (SOUTHERN , ) In this work several examples of geomorphological a b and geothematic maps are presented, realized in the Abruzzo region at different scales ranging form 1:15.000 to 1:50.000, within the research activities of the Laboratory of Tectonic Geomorphology and GIS, Department of Engineering and Geology, “G. d’Annunzio” University of Chieti-Pescara. Several examples of Morphotectonic maps, Slope instabilities maps, Geomedical maps and Geotourist maps are presented. These maps are realized in the main morphostructural sectors of the Abruzzo Region: chain, piedmont area and coastal plain. Lithological units outcropsing in the Osento river basin. (a) Limestone and marl limestone (CAM), near ; (b) All the maps are based on the ISPRA (CARG Pili sandy shale (SASP). Project) guidelines, eventually integrated and/or c d modified in order to be adapted to specific scopes and different scales of the maps. All the maps are realized within GIS environment. MORPHOTECTONIC MAPS The creation of Morphotectonic maps is based on drainage basin scale geomorphological analysis within GIS environment by means of: DEM- and map-based cartographic analysis, morphometry of orography and hydrography (raster and vector data 1:25,000 - 1:10,000 scale, 5m grid DEM), photogeology analysis (1:10,000 - 1:33,000 scale), Lithological units outcropsing in the Osento river basin. (c) Masseria Mucci sands and gravels (SSCM); (d) Masseria Quaternary continental deposits, fluvial terraces and Mancini gravels (GM). morphostructural field mapping (1:10,000 scale), morphotectonic profiles that couple landform, deposits and terraces. The morphotectonic maps incorporates more main sections: · orography and hydrography section; · main morphotectonic map section; · quaternary fluvial deposits and terraces section; · longitudinal morphotectonic profile section. The morphotectonic maps are realized in the Chain area (Marsica and Peligna region, Central Apennines, Morphotectonic elements in the Osento River basin. (a) , escarpment of the cuesta located in the SW sector of scale 1:50.000) and in the Piedmont-Coastal area the basin. (Aventino River basin – lower Sangro River area, SE Abruzzo scale 1:50.000; Osento River basin, SE Abruzzo, scale 1:30.000). The maps presented in this work are the base for recognition of morphotectonic features at basin scale, detection of tectonic control on landscape, and reconstruction of paleo-landscapes. They provide a contribution to define the main phases of post orogenic landscape evolution of the piedmont area of the Apennines chain, resulting from the link of alternating morphotectonics and surface processes, due rock uplift processes, local tectonics and alternating slope and fluvial processes. Morphotectonic elements in the Osento River basin. Structural scarp in the NE sector of the basin. SLOPE INSTABILITIES MAPS Slope instabilities maps are realized by geoscientist at different scales, with different methods and for different purposes (research or applied purposes; landslides mapping, soil erosion mapping, flood mapping, etc.). In this work, maps of the geomorphological instabilities, triggered by heavy Morphotectonic elements in the Osento River basin. Asymmetric valley near . rainfall events that affected the Coastal area Abruzzo Region in the last 5 years, are presented. These maps are mainly based on aerial photo MAP OF SLOPE INSTABILITY DUE TO HEAVY RAINFALL IN THE NORTHERN ABRUZZO COASTAL AREA (2007 AND 2011 EVENTS) interpretation (taken after the rainfall events) and field geomorphological mapping carried on immediately after the rainfall events. Particularly, the maps presented refers to the 1-2 March 2011 heavy rainfall event (up to ~200 mm/day) which affected the coastal slopes and the coastal hills of the northern Abruzzo. The main mapped landform are due to slope instabilities (earth flows, mud flows, gullies, areas affected by rill erosion) and flooding (flooded areas, crevasse splays). a These kind of maps are the base for flooding and slope instabilities hazard analysis and for the estimation of sediment volumes eroded during the events. This is particularly important for minor drainage basins of coastal slopes and coastal hills where erosion and hazard are frequently underestimated. GEOMEDICAL MAPS Geomedical maps are recently developed in many countries incorporating multiple land features: bedrock lithology, surface deposits, pedology, geochemistry, disease distribution and incidence etc. LEGEND b In this work the first example of geomedical maps River realized in the Abruzzo regionis presented. It is based Gully erosion on the comparison of geological data and Flood area epidemiological data in order to evaluate the disease Earth flow Examples of gully erosion and flooding triggered by the 2007 River bed erosion deepening heavy rainfall event in the Tortoreto area. a) southern slope risk induced by natural and anthropic sources in the of Tortoreto; gully erosion ; b) coastal area of Tortoreto; Slope affected by rill wash main fluvial valleys of the piedmont area of the flooding and beach erosion. a b c Abruzzo region.

GEOTOURIST MAPS In the geotourist maps, geology and geomorphology GEOMEDICAL MAP OF THE PESCARA RIVER BASIN (CENTRAL ABRUZZO, iTALY) are presented in an easy and educational way, as a Geo/environmental risk map base of a new way of reading landscape and tourism. (concerning Leukemia, Lymphoma and Myeloma) Going back over a history wrote during millions of years, where books are rocks, pages are layers, Litological Map Landuse Map words are fossils and ink ...is time. In this work the first geotourist map in Abruzzo (southern chain piedmont area) realized in the Aventino - middle Sangro area is presented. Table of the Pressure factors The map is reinterpreted from geological maps, distinguishing outcropping rocks as concern their surface expression into distinct geological landscapes. Limestone, marls, sandstones, clays, chalks, gypsum, gravels and landforms are presented as windows over a 200 million years history that today can be observed in a unique “breathtaking” landscapes rich of colours and suggestions, labelled with appealing names (i.e. the sliding rocks, the shining hills, the floating mountains). Symbols highlight the location of main geological and geomorphological features (i.e. national geosites, fossil sites, oil well, caves, glacial cirque remnants, and other geological interest areas). Finally, tourism facilities (offices, information centres, museums, trails, etc.) are added to the geological and geomorphological aspects in order to complete the geotourist map. The backside of the map and the explanatory notes include text and figures explaining features and origin of different types of rocks and related landscapes. CONCLUSION This work is a contribution of data and examples to enhance the value of modern geomorphological GEOTOURIST MAP OF THE AVENTINO RIVER AND MEDIO SANGRIO RIVER (SOUTHERN ABRUZZO, iTALY) and geothematic maps for several purposes such as: research activities concerning morphotectonics Cima and landscape evolution, hazard and slope instabilities dell'Altare Grotta 2542 analysis, geomedical analysis, geotourism and Canosa M.
