“…In the literature, the ratio between Smf and Vf is used to determine the tectonic activity of faults (e.g., Rockwell et al 1984, Silva et al 2003, Yıldırım 2014, Softa et al 2018, Saber et al 2018, Özsayın, 2016. Smf values were calculated for the sub-basin areas where are located nearby normal fault splays of GBFZ.…”

“…The geometry of drainage basins can be determined from basin shape indices (Bs) (Cannon 1976, Bull and McFadden 1977, Ramírez-Herrera 1998, El Hamdouni et al 2007, Omidali et al 2015, Saber et al 2018. Bs indice can be defined by the following formula;…”

“…Using geomorphic indices plays a crucial role to determine the relationship between erosion processes and tectonic activity of the region since the early 2000s (e.g., Silva et al 2003, Bull 2007, Özkaymak and Sözbilir 2012, Özsayın 2016, Sağlam and Düzgün 2017, Saber et al 2018. The effect of tectonic activity on drainage systems and landforms can be explained using geomorphological modelling and morphometric approaches.…”

“…However, not only river offsets but also detailed studies about other geomorphic indices such as stream length gradient indice (SL), mountain-front sinuosity (Smf), valley floor width to height ratios (Vf), drainage density (Dd), and hypsometric integral (Hi) shed light on determining the tectonic activity of the regions with a vertical component of motion along the strike-slip faults (e.g., Owen et al 1999, Keller and DeVecchio 2013, Khalifa et al 2018. Therefore, to evaluate tectonic activity of GBFZ is used high-resolution satellite images (e.g., Burbank and Anderson 2001;Silva et al 2003, Saber et al 2018, Baize et al 2015, Crupa et al 2017, Walker and Allen 2012, Khalifa et al 2018, Baharvand et al 2020 and GIS-based software such as ArcGIS® 10.5 (ESRI) (Faghih et al 2016). GBFZ is located in the western part of the İBTZ (Kaya 1979, Sözbilir et.al 2003a, Emre et.al., 2005.…”

“…Bl is the length of the drainage basin, and Bw is the length of the widest part of the basin. High Bs values indicate the drainage basin's longitudinal geometry, indicating high tectonic activity (Ramírez-Herrera 1998,Softa et al 2018, Saber et al 2018). This value is divided into three classes to define the degree of activity of tectonics:…”

To investigate the recent landscape evolution of the orogenic Turkish–Iranian Plateau (TIP) and the Lesser/Greater Caucasus ranges, we perform a quantitative analysis of topography and drainage networks at a regional scale. This analysis focuses on climatic–topographic swath profiles, local relief distribution, longitudinal river profiles, normalized channel steepness index (ksn), paleo‐river profile, and chi analysis (χ). In general, we find that the evolution of topographic relief and river networks are locally controlled by Late Cenozoic volcanism, contrasts in rock strength, and neotectonic activity along regional tectonic structures. However, our results show that the influence of these factors on the landscape evolution of the Greater Caucasus is significantly different from the Lesser Caucasus and TIP. This study shows that a combination of enhanced aridity, rapid uplift of orographic barriers along the TIP margins, and exposure of resistant rock types associated with the regional volcanic activity resulted in low‐relief plateau and the Lesser Caucasus surfaces that are preserved in the upper/middle Kura–Arax and Qezel‐Owzan river catchments. High local relief in the flanks of the Greater Caucasus and west Alborz, downstream increase in channel steepness, and perturbations in the χ plots of the three main rivers indicate that the topography is in a transient state.We reconstruct the paleo‐river profiles from the relict section of the upper Kura–Arax and Qezel‐Owzan rivers and show that the last drastic fall of the Caspian base‐level, which occurred during the Late Miocene–Early Pliocene, can explain the incision of ~500–1000 m gorges (i.e., Amardos) below major knickpoints. Furthermore, local cross‐divide differences of the χ parameter reveal that disequilibrium in the plan‐form geometry of the drainage networks, attributed to the upstream migration of the regional knickpoints towards the plateau interior and integration of plateau areas into the external fluvial system.

Tectonic geomorphology of the Aras drainage basin (NW Iran): Implications for the recent activity of the Aras fault zone

Complex geology and tectonics of the NW Iran, the Caucasus region, and Eastern Turkey, are responsible for the present‐day landscapes of the region. The Aras drainage basin located in Iran, Azerbaijan and Armenia borders, provides an appropriate geographical environment for systematically studying the landforms produced or modified by active tectonic processes. Several morphometric indices were calculated for 114 sub‐basins to assess relative tectonic activity levels. Results were evaluated using two different methods; Index of Active Tectonics (IAT) and Analytical Hierarchy Process (AHP) methods. IAT results show that 2% of the sub‐basins belong to very high, 25% to high, 46% to moderate and 27% to low tectonic activity classes. AHP results, display that 12% of the sub‐basins belong to very high, 25% to high, 43% to moderate, and 20% to low tectonic activity classes. Results of both methods show approximate consistency and indicate that the tectonic activity along the Aras drainage basin is moderate to high and decreases from southwest to the northwest which is probably due to terminating fault branches in young unconsolidated deposits or strain partitioning processes. The major fault zones (e.g., Aras, Pambak–Sevan–Sunik, Akera, and Moghan fault zones) include areas with very high and high tectonic activity classes. Accordingly, the uplift rates have been estimated as >0.5 mm/yr for central and western parts, whereas the uplift rates are relatively less in the eastern part (<0.5 mm/yr). The Aras fault zone includes five active structural segments that the main Aras and Horadiz segments of them show relatively higher tectonic activity.
