The Rieti intermontane basin is one of the western tectonic depressions of the Central Apennines. Its infilling deposits are currently cut by the Farfa River, a left tributary of the Tiber River with a 132 km2 wide drainage basin. It currently flows from the Sabini Mts. (Central Apennines) into the Tiber River to the WSW. In the upper basin, the ri...

The analysis of the top surface confirmed that it is strongly dissected by the NW-SE master fault along with E-W normal fault systems (Fig. 4a). The basal surface is strongly dissected by the NNW-SSE and WSW-ENE fault systems which are located 10 km south of the present Rieti plain. This suggests that they were active during the depositional Gelasian phase (Fig. 4b). These fault systems did not intersect the top surface, indicating that their activity waned during the Early ...

... In the Pliocene-to-Holocene extensional intermontane basins, the base of the non-marine succession provides a minimum age for the onset of extension but in several basins the base is either not exposed (e.g., X: Fucino Basin, Cavinato et al., 1994) or erosive with a large time gap following the foreland basin system succession (e.g., VII: Tiberino Basin, Mancini et al., 2007;Cosentino et al., 2017). The western intermontane basins, north of Rome (VII and IX: Tiberino and Rieti basins; Figs. 1 and 2), were filled with uppermost Piacenzian-Gelasian, lacustrine continental fluvial sediments, laid with an angular unconformity over the Mesozoic-Cenozoic bedrock (Mancini et al., 2007;Fubelli et al., 2014;Cosentino et al., 2008Cosentino et al., , 2017. Upper Piacenzian-Gelasian to Gelasian sediments are also the basal lacustrine and fluvial infill of the central intermontane basins (X: Fucino; Cavinato et al., 2002;Centamore et al., 2006b;Giaccio et al., 2019;Mondati et al., 2021; XI and XII: L'Aquila; Cosentino et al., 2017). ...
Stratigraphic and thermochronologic data are used to study the processes that shaped the topography of the central Apennines of Italy. These are part of a major, active mountain belt in the center of the Mediterranean area, where several subduction zones control a complex topography. The Apennines were shaped by contraction at the front of the accretionary wedge overlying the subducting Adria microplate followed by extension at the wedge rear in response to eastward slab roll-back. In the central Apennines, intermontane extensional basins on the western flank rise eastward toward the summit. We contribute with new data consisting of 28 (U-Th-Sm)/He and 10 fission track ages on apatites to resolve a complex pattern of thermal histories in time and space, which we interpret as reflecting the transitional state of the orogen, undergoing a two-phase evolution related to initial slab retreat, followed by slab detachment. Along the Tyrrhenian coast, we document cooling from depths ≥3−4 km occurring between 8 and 5 Ma and related to the opening of marine extensional basins. Post−5 Ma, a broader region of the central Apennines exhibits cooling from variable depths, between <2 km in most areas and ≥3−4 km in the northeast, and with different onset times: at ca. 4 Ma in the west, at ca. 2.5 Ma in the center and northeast, and at ca. 1 Ma in the southeast. Between 5 and 2.5 Ma, exhumation is associated with modest topographic growth during the late stages of thrusting. Since 2.5 Ma, exhumation has concurred with the opening of intermontane basins in the west and in the east, with regional topographic growth and erosion, that we interpret to be associated with the locally detaching slab.

The range of natural environmental degradation caused by anthropogenic activity may include geomorphological forms such as dunes resulting from the build-up activity of the wind. In effect, such environmental transformation affects changes connected not only with their relief, but also with the presence and health of diverse plant and animal inhabitants. The subject of the survey was a parabolic dune with asymmetric shape, the sand of which was subjected to exploitation over many years. Terrain data acquired by means of GNSS (Global Navigation Satellite Systems) served to elaborate the present relief of the surveyed dune and to reconstruct its primary relief. These were mainly places where the impacts of human activities were recorded. For this purpose, ordinary kriging (OK) estimation was performed. Simultaneously, satellite data and UAV (Unmanned Aerial Vehicle) imaging were acquired, and subjected to image fusion in order to acquire near infrared bands (NIR), red, green, blue in high spatial resolution. These in turn were applied so as to estimate the condition of the vegetation overplanting the dune and surrounding terrain. The correctness of the modelling was verified by cross-validation (CV), which disclosed low error values. Such values in present and primary relief were, respectively, mean error (ME) at −0.009 and −0.014, root mean square error (RMSE) at 0.564 and 0.304 and root mean square standardised error (RMSSE) at 0.999 and 1.077. Image fusion, with use of pansharpening allowed a colour-infrared composition (CIR) and a Modified Chlorophyll Absorption in Reflectance Index 1 (MCARI1) to be obtained. Their analysis disclosed that vegetation on the dune is characterised by worse health condition as compared with the surrounding area thereof. The proposed approach enabled the environmental condition of the surveyed dune to be analysed, and thereby it allows for a determination of the consequences of further uncontrolled sand recovery without taking into account the historical cartographic materials customarily considered to be the main source of information.
... Since the Early Pleistocene, the orogen underwent regional uplifting and, contemporaneously, local extensional tectonics determined the development of several tectonic basins, mainly bordered by NW-SE-oriented and SW-dipping normal to transtensional faults [27][28][29][30][31]. Furthermore, in the same period, the coincidence of volcano-tectonic and tectonic-sedimentary events contributed to the evolution of the Tyrrhenian hinterland, including large peri-Tyrrhenian volcanic districts and basins [32][33][34]. The direct combina-tion of tectonic processes (i.e., Miocene-Pliocene thrusting and Quaternary extensional tectonics), regional uplift, and geomorphological processes (e.g., slope, fluvial, karst, and glacial processes) resulted in the reorganization of drainage systems and intermontane basins, development of several valleys with flights of fluvial terraces, and formation of the present-day landscape [5,7,16,35,36]. The geological framework is the result of the Neogene-Quaternary evolution of an orogenic system (chain-foredeep-foreland) migrating eastward [26]. The major thrust systems, NW-SE and N-S-oriented and gently dipping towards SW, were stacked on each other, involving different structural and paleo-geographical domains (carbonate platforms and related margins, slope, and pelagic basin) featuring different tectonic orientations. ...
Quaternary continental deposits record spatio-temporal changes of the landscape and offer insights for drainage network analysis and paleoenvironmental reconstructions. This paper focuses on the Turano River, a left tributary of the Velino River, which flows in the southwestern Abruzzo area at the boundary with Lazio Region. Its basin preserves lithological and morphological field evidence particularly suitable for reconstructing the long-term geomorphological evolution of the Central Apennines and the drainage network development. In detail, the Turano River was investigated through a drainage basin-scale analysis incorporating morphometric analysis, field mapping, continental deposits analysis, and integrated drainage network analysis. This approach allowed us to define a drainage network reversal process, clearly highlighted by the spatial arrangement of continental deposits, spanning from Upper Pliocene to Holocene. The results also indicated tectonic activity as the main factor driving incision and river inversion processes. The work contributes to identifying and describing the main steps of the Quaternary landscape evolution of this mountainous catchment and its morphoneotectonic framework. Therefore, it could represent a methodological tool for multidisciplinary studies in similar mountainous catchments to support any territorial planning activity, from large infrastructure localization (i.e., artificial dams) to sustainable land management.
... Tectonics and climate influenced the long-term landscape evolution of this sector of the Apennines and the drainage network underwent important phases of planoaltimetric re-organization, mainly consisting in stream piracy and cyclic alternation of erosional and aggradational episodes, as already testified within adjacent river basins in central Apennines (Aringoli et al. 2014;Fubelli et al. 2014). ...
Scenarios of earthquake-induced landslides are necessary for seismic microzonation (SM) studies since they must be integrated with the mapping of instability areas. The PARSI-FAL (Probabilistic Approach to pRovide Scenarios of earthquake-Induced slope FAiLures) approach provides extensive analyses, over tens to thousands of square kilometers, and is designed as a fully comprehensive methodology to output expected scenarios which depend on seismic input and saturation conditions. This allows to attribute a rating, in terms of severity level, to the landslide-prone slope areas in view of future engineering studies and designs. PARSIFAL takes into account first-time rock-and earth-slides as well as re-activations of existing landslides performing slope stability analyses of different failure mechanisms. The results consist of mapping earthquake-induced landslide scenarios in terms of exceedance probability of critical threshold values of co-seismic displacements (P[D ≥ Dc|a(t),a y ]). PARSIFAL was applied in the framework of level 3 SM studies over the municipality area of Accumoli (Rieti, Italy), strongly struck by the 2016 seismic sequence of Central Apennines. The use of the PARSIFAL was tested for the first time to screen the Susceptibility Zones (ZS FR) from the Attention Zones (ZA FR) in the category of the unstable areas, according to the guidelines by Italian Civil Protection. The results obtained were in a GIS-based mapping representing the possibility for a landslide to be induced by an earthquake (with a return period of 475 years) in three different saturation scenarios (i.e. dry, average, full). Only 41% of the landslide-prone areas in the Municipality of Accumoli are existing events, while the remaining 59% is characterized by first-time earth-or rock-slides. In dry conditions, unstable conditions or P[D ≥ Dc|a(t),a y ] > 0 were for 54% of existing landslides, 17% of first-time rock-slides and 1% of first-time earth-slides. In full saturation conditions, the findings are much more severe since unstable conditions or P[D ≥ Dc|a(t),a y ] > 0 were found for 58% of the existing landslides and for more than 80% of first-time rock-and earth-slides. Moreover, comparison of the total area of the ZA FR versus ZS FR , resulted in PARSIFAL screening reducing of 22% of the mapped ZA FR .
... There was an inverse correlation between dissolved oxygen and water temperature, as reported in other studies [11,52]. The slightly basic pH values for the waters are typical of the calcareous substrate on which the Farfa River flows, confirming the results of other studies carried out in the same basin [11,53]. No significant nutrient value changes were observed that might suggest eutrophication processes. ...
Anthropogenic pressure and climate change can affect the structural and functional role of aquatic ecosystems. Moreover, human health can be directly or indirectly affected by environmental factors, due to exposure to contaminants. In central Italy, the summer of 2017 was characterized by high temperature (heat wave) and low rainfall that had an impact on the main reservoir of drinking water (a central Italian lake). The purpose of the study was to evaluate the environmental impact of water abstraction in a Tiber River tributary, as well as to increase knowledge of the link with human and environmental health.
The experimental approach was based on the assessment of environmental parameters and ecological quality status through the analysis of biological communities (WFD 2000/60/EC). Furthermore, faecal indicator microorganisms were recovered to evaluate the potential risks for human health. Water and biological samples were collected at three sampling points along the river in different campaigns. The results showed that the sites generally have a good ecological status, although a slight change of boundary class was also observed. It is difficult to establish the cause of this lowering of quality, since it would require a longer period of observation of the communities to determine if it is a reversible process or not, or if it might depend on water abstraction. In conclusion, the ecosystem approach adopted in this study provided a full vision useful for the planning of prevention and/or protection measures for aquatic ecosystems and for human health.
... Furthermore, the upstream migration rates of knickpoints driven by fault-related base-level changes can be used to reconstruct the deformation history of faults (Commins et al., 2005;Wobus et al., 2006;Boulton and Whittaker, 2009;Whittaker and Walker, 2015;Whittaker, 2016, 2017). The fit between geomorphic inferences of base-level change and predictions from fault growth and interaction models (Roda-Boluda and Whittaker, 2016Whittaker, , 2017 has been tested where slip rates and fault throws are well-constrained, as for example through geomorphic markers (Briais et al., 1990;Mayer and Vincent, 1999;Pérez-Peña et al., 2009;Cundy et al., 2010;Galli et al., 2012Galli et al., , 2017Fubelli et al., 2014;Giano et al., 2014;Della Seta et al., 2017) and/or through paleoseismological data (Schwartz and Coppersmith, 1984;Sieh et al., 1989;Cowie, 1998;Galli et al., 2008). Although slope-area analysis of channel networks has frequently been used to reveal patterns of erosion and, by inference, tectonic activity (Stock and Montgomery, 1999;Whipple, 2001, 2012;Snyder et al., 2003), digital topographic data and their derivatives (i.e. ...

In L'Aquila Basin, the Madonna della Strada synthem (Calabrian) is cut into the abandon- ment surface of the San Demetrio synthem (Valle Daria, 850 m above sea level), which re- gionally corresponds to the Gelasian abandon- ment surface of the Rieti basin fill ( Barisone et al., 2014;Cosentino et al., 2014;Fubelli et al., 2014; Fig. DR1 [see footnote 1]). Simi- larly, in the Tiberino Basin, above the Upper Piacenzian-Gelasian lake sediments, a promi- nent angular unconformity separates the Fosso Bianco Formation from the overlying Lower Pleistocene deposits of braided stream and marshy alluvial plain origin (Santa Maria di Ci- ciliano Formation; Basilici, 1995Basilici, , 1997). ...
... In this scenario, the inter- montane basins of the central Apennines re- cord ~3 m.y. of continued crustal extension in response to a first phase of mantle upwell- ing above the Adria subducting slab (from 3 to 2 Ma; Fig. 16) and a second phase of dy- namic mantle upwelling possibly starting from ca. 2 Ma, probably due to slab detachment under the central Apennines ( Faccenna et al., 2014). The second phase of mantle upwelling could be responsible for the strong tectonic uplift (~260 m) that occurred in central Italy close to the Gelasian-Calabrian transition ( Cosentino et al., 2009), which possibly in- duced the early Pleistocene reorganization of the central Apennine drainage systems ( Fubelli et al., 2014;Piacentini and Miccadei, 2014). ...
Study of the tectonically active L’Aquila
Basin offers new insights into both the creation
of the extensional intermontane basins
of the central Apennines of Italy and their
tectono-sedimentary evolution through
time. The combination of large mammal
remains, ostracods, molluscs, Mousterian
tools, and 14C dating allows better definition
of the onset and stratigraphic evolution
of the L’Aquila Basin. Interpretation of a
seismic reflection profile and well-log data
allow evaluation of the subsurface setting
of this sedimentary basin and its tectono-sedimentary
evolution. The occurrence of
a wedge-shaped seismic unit at the base of
the basin sedimentary succession defines
the first phase of basin fill during a late
Piacenzian–
Gelasian synrift stage. Activity
along the main fault of the extensional
fault system responsible for the onset and
subsequent development of the western
sector of the L’Aquila Basin (L’Aquila–
Scoppito subbasin) migrated from southwest
to northeast, reaching the presently
active Mount Pettino normal fault only in
the late Pleistocene–
Holocene. The onset of
sedimentation in the L’Aquila Basin was
synchronous with the onset in the Tiberino
Basin, and so the idea that these extensional
intermontane basins become progressively
younger from the Tyrrhenian toward the
Adriatic side of the central Apennines is
rejected. In the northern and central Apennines,
only two major syndepositional extensional
domains can be recognized: a late
Miocene rifting area, which includes all the
late Miocene extensional basins in Tuscany,
and a late Pliocene to earliest Pleistocene
rifting area, which possibly includes all
the intermontane basins from the Tiberino
Basin to the Sulmona Basin. The different
time gaps between compressional and extensional
deformation at any given locality in
the central Apennines could indicate a partial
decoupling of processes responsible for
the migration of shortening and extension
toward the foreland. Diachroneity between
the eastward migration of shortening in the
foreland and extension in the inner part of
the orogen supports the notion that the central
Apennines were created as a result of a
partially decoupled collision zone. Study of
the onset of the central Apennine extensional
intermontane basins, together with their
seismic activity, indicates that the central
Apennine postorogenic extensional domain
represents an archive of ~3 m.y. of continued
crustal extension. These findings help to
refine models of the long-term extensional
rate of the central Apennines, and they provide
a basis for more reliable seismotectonic
models for one of the most seismically active
sectors of the central Mediterranean area.
... These ranges are presently separated by longitudinal valleys and cut by transverse gorges that allowed the connection between Northern and Central Italy. In fact, the river network of the Umbria-Marche Apennines started to set up after the emersion of the ridges from the sea, but underwent continuous readjustments (Fubelli et al. 2014); in particular, Quaternary tectonics was responsible for the opening of several depressions bounded by normal faults (Cavinato and De Celles 1999;Melelli et al. 2014). The latter are represented by Plio-Pleistocene intermontane basins, mainly clustered on the Tyrrhenian slope of the Apennines and interrupting the architecture of the mountain ranges. ...
The landscape of the Umbria
-Marche
Apennines (Central Italy) shows a rhythmic sequence of “whaleback” anticlinal ridges separated by longitudinal synformal valleys. In this topographic arrangement, flat-floored tectonic depressions appear which enclose a wide range of landforms, and witness the continuous balance between tectonic forces, Quaternary climatic phases and drainage network adjustment. Fault scarps and triangular facets
characterize the bordering slopes where thick talus deposits and landslide
s highlight the gravitational component. Karstic landforms as dolines and caves and fluvial features testify to the action of water. The resulting landscape is, for a visitor, like an incomparable geological handbook.

Il Farfa è uno dei più importanti affluenti della riva sinistra del fiume Tevere, nasce nei pressi di Frasso Sabino a circa 400 m s.l.m. sulle propaggini meridionali dei Monti Sabini e sfocia a Nazzano, in provincia di Roma. Attualmente con un bacino idrografico di 132 km 2 scorre verso Ovest-Sud Ovest (Fubelli et al., 2014) e si presenta a carattere torrentizio con un alveo la cui componente ghiaia-ciottoli è preponderante. ...

In particolare, l'interazione tra il sollevamento e i cambiamenti climatici hanno causato la formazione dei due principali ordini di terrazzi, riconoscibili nella valle attuale del Fiume Farfa a differenti quote.

L’obiettivo del seguente lavoro di tesi è quello di studiare l’area dell’Appenino centrale interessata da eventi tettonici, responsabili di intensi cambiamenti della rete idrografica e del regime fluviale, impostatisi dal Pliocene superiore al Pleistocene medio.
Il settore periadriatico abruzzese è caratterizzato da diversi thrust posti al margine del fronte esterno della Maiella, porzione emersa del sistema orogenico appenninico, corrispondente al dominio di avanfossa. L’evidenza della tettonica recente dell’area è riscontrabile grazie agli alti topografici e alle strutture compressive che hanno deviato il corso dei fiumi dalla loro naturale direzione SW-NE. I bacini intermontani di Rieti e del Fucino sono due depressioni tettoniche dell’Appennino centro-occidentale che hanno causato lo spostamento delle linee spartiacque e influenzato le linee di drenaggio a partire dal Pleistocene inferiore. Fiumi quali il Farfa, il Velino e il Salto prima scorrevano in ampie valli, poste tra le vette appenniniche non ancora interessate da estensione, ed hanno vissuto una fase deposizionale rilevante provocata in principio dallo smantellamento dei rilievi non ancora carbonatici ma di origine sedimentario-clastica. Queste fasi hanno lasciato testimonianze geologiche, numerosi affioramenti di sedimenti fluviali caratterizzati da uno spessore sproporzionato rispetto agli attuali bacini idrografici, ed evidenze geomorfologiche, tracce di paleopaesaggi e resti di paleosuperfici di erosione.
Il fine del presente lavoro di tesi è quello di individuare le suddette evidenze, comprendere la relazione tra morfologia, tettonica e cambiamenti climatici con la prospettiva di analizzare e confrontare la risposta e l’evoluzione del reticolo idrografico dei due diversi settori appenninici. Tale studio è composto da una parte di lavoro di campagna e da una parte di lavoro di laboratorio. Il rilevamento geologico di terreno ha come scopo il riconoscimento dei depositi plio-pleistocenici seguendo le indicazioni di articoli e lavori redatti dagli anni ’70 ad oggi. Un’analisi geomorfologica è eseguita per il censimento e la classificazione delle paleosuperfici, aiutandosi con il lavoro in ambiente GIS per l’estrazione delle medesime da modelli digitali di elevazione del terreno. Infine sono state eseguite le analisi su piattaforma GIS dei reticoli idrografici attuali e precedenti alla fasi tettoniche quaternarie traendone le opportune conclusioni.
... The common ground among all these applications is that they are spatially integrated, and hence data are handled in a GIS environment at least in part. To mention some scientific applications, we begin with chronologically early ones in Volcanology (Neri et al., 2008;Favalli, 2010b, 2011;Tarquini et al., 2012b), then Geomorphology (Intrieri et al., 2013;Fubelli et al., 2014;Marchesini et al., 2015), tectonics (Mazzoli et al., 2014), Seismology (Vessia et al., 2013), Geodynamics (Roberts et al., 2013), Gravimetry (Lo Re et al., 2016), Hydrology Carisi et al., 2015), Sedimentology (Fontana et al., 2014), Glaciology (Pellitero et al., 2016), disaster simulations (Ward and Day, 2011), climate change (Salerno et al., 2014), Zoology (Imperio et al., 2015) and Archaeology (Huyzendveld et al., 2012;Pelgrom et al., 2014;Patacchini and Nicatore, 2016;Casarotto et al., 2016), with other applications covering also Ecology (Pornaro et al., 2016;Jona Lasinio et al., 2017), Ornithology (Brambilla et al., 2016), Forestry (Van doninck et al., 2013), and environmental and city planning (Ellul et al., 2013, Paladini Mendoza et al., 2016. The TINITALY DEM demonstrated to be particularly useful for the routinely processing of satellite images such as orthorectification and georeferencing, and has been often used in conjunction with remote sensing analyses (e.g. ...
The increasing availability of high resolution digital elevation models (DEMs) is changing our viewpoint towards Earth surface landforms. Nevertheless, large-coverage, intermediate-resolution DEMs are still largely used, and can be the ideal choice in several applications based on the processing of spatially-integrated information. In 2012 the Istituto Nazionale di Geofisica e Vulcanologia opened a website for the free download of the “TINTALY” Digital Elevation Model (DEM), which covers the whole Italian territory. Since then, about 700 users from 28 different countries have been accredited for data download, and a report of 4 years of data dissemination and use is presented. The analysis of the intended use reveals that the 10 m-resolution, seamless TINITALY DEM is of use for an extremely assorted research community. Accredited users are working in virtually any branch of the Earth Sciences (e.g. Volcanology, Seismology, and Geomorphology), in spatially integrated humanities (e.g. History and Archaeology), and in other thematic areas such as in applied Physics and Zoology. Many users are also working in local administrations (e.g. Regions and Municipalities) for civil protection or land use planning purposes. In summary, the documented activity shows that the dissemination of seamless, large coverage elevation datasets can fertilize the technological progress of the whole society providing a significant benefit to stakeholders.
