“…The morphotectonic investigations presented in this work provide a contribution to the definition of the role of selective erosion and tectonics in landscape evolution and their related timings, particularly in areas such as the Aventino -lower Sangro valley, with a complex geological setting-different types of succession and lithologies outcropping -and recent evolution -post Early Pleistocene in the whole NE sector -(see also Bahrami, 2012;Centamore et al, 1996;Ciccacci et al, 1986;D'Alessandro et al, 2003D'Alessandro et al, , 2008Della Seta et al, 2008;Del Monte, Di Bucci, & Trigari, 1996;Figueroa & Knott, 2010;Gioia, Schiattarella, Mattei, & Nico, 2011;Goldsworthy & Jackson, 2000;Miccadei et al, 2004;Miccadei et al, 2011;Molin et al, 2004;Nesci et al, 1995;Pazzaglia, 2013;Wegmann & Pazzaglia, 2009). …”

This work presents the Morphotectonic map of the Aventino-Lower Sangro valley, located in the southern Abruzzi area, and extending from the Apennines chain to the eastern piedmont, from the Maiella Mountain to the Adriatic coast. It is the result of an extensive drainage basin scale geomorphological analysis carried out in the Abruzzi area and incorporates four main sections: orography and hydrography (upper right on the map); morphotectonic section (centre and left on the map); quaternary fluvial deposits and terraces section (right on the map) and the long morphotectonic profile (lower right on the map).The map presented in this work provides a basis for the recognition of morphotectonic features at basin scale, the detection of tectonic control on landscape, and the reconstruction of paleo-landscapes. It contributes to defining the main phases of the post-orogenic landscape evolution of the transition zone between the Apennines chain and the eastern piedmont area, resulting from the combination of alternating morphotectonics and surface processes, due to rock uplift processes, local tectonics and slope and fluvial processes.

“…In order to discriminate between V-shaped and U-shaped flat-floored valleys, valley floor width-toheight ratio (Vf ) was calculated as the width of the valley floor divided by the average height of the valley divides (Bull and McFadden, 1977;Figueroa and Knott, 2010): Subsequently linear relationship between parameter means were examined.…”

“…For a specific area, using the several indexes rather than an index provides more meaningful results [2]. Geomorphologic indexes have been used in different areas by numerous scientists and the result has been approved, for example, in Costa Rica's Pacific coast [3], the Mediterranean coast of Spain [4] and the southern Sierra Nevada Mountains of California [5]. In this study, many morphometric parameters have been evaluated and by determination of I at index and conducting analytic hierarchy process, relative tectonics of the region has been examined.…”

Geomorphic indices are useful tools for studying relative active tectonics of a specific area. In this study, the relative active tectonics of Bozgoush region (NW of Iran) has been investigated based on Geomorphic indices. The studied indexes include: the stream length-gradient (SL), hypsometric integral (Hi), the ratio of valley floor width to valley height (Vf), the shape of the drainage basin (Bs), the sinuosity of mountain front (Smf), asymmetric factor of drainage basin (Af) and transverse topographic symmetry factor (T). In the present study, gathered data from various morphometric indexes of six basins are aggregated, and their obtained result is provided as relative active tectonics of the region or Iat index that shows a proper illustration of the relative active tectonics of the mentioned region. In order to develop a correct analysis of the mentioned area, the AHP (analytic hierarchy process) model with a studied weight, the final overlapped layer of relative tectonics is prepared with applying coefficients. With the comprehensive field studies, evidences like deep valleys, river bed immigration, landslides, sudden change in river cycles and surfaces of faults were found that are in good consistence with obtained data of relative active tectonics of the region. After measuring these indexes, it was found that Aydoghmush and OujanChay basins have a high relative active tectonics. With regard to the obtained results of present study, it seems that Tabriz fault has the most seismic and motional potential in northern basins of the region. In addition, in Aydoghmush basin, in southern part of the region, Qeynarjehchartagh fault has a high active tectonics that according to the estimated values has been identified as an active young structure in the region.
