INTRODUCTION
In this work several examples of geomorphological
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.
All the maps are based on the ISPRA (CARG
Project) guidelines, eventually integrated and/or
modified in order to be adapted to specific scopes
and different scales of the maps. All the maps are
realized within GIS environment.

CONCLUSION
This work is a contribution of data and examples
to enhance the value of modern geomorphological
and geothematic maps for several purposes such
as: research activities concerning morphotectonics
and landscape evolution, hazard and slope instabilities
analysis, geomedical analysis, geotourism and
enhancing geological and geomorphological heritage.

GEOTOURIST MAPS
In the geotourist maps, geology and geomorphology
are presented in an easy and educational way, as a
base of a new way of reading landscape and tourism.
Going back over a history wrote during millions of
years, where books are rocks, pages are layers,
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.
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.

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.
In this work the first example of geomedical maps
realized in the Abruzzo regionis presented. It is based
on the comparison of geological data and
epidemiological data in order to evaluate the disease
risk induced by natural and anthropic sources in the
main fluvial valleys of the piedmont area of the
Abruzzo region.

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),
Quaternary continental deposits, fluvial terraces and
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,
scale 1:50.000) and in the Piedmont-Coastal area
(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.
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
rainfall events that affected the Coastal area Abruzzo
Region in the last 5 years, are presented.
These maps are mainly based on aerial photo
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).
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.
