Tectonics
Morphotectonics and Slip rate of the Khazar fault in Central Alborz, (North of Iran)

Hamid Nazari; Jean-Francois Ritz; Ara Avagyan

Volume 31, Issue 2 , September 2021, , Pages 101-110

https://doi.org/10.22071/gsj.2021.259868.1863

Abstract
  The Alborz mountain range accommodates some of the convergence between Central Iran and Eurasia. At present, the kinematics of the range involves a strain partitioning mechanism, and is associated with clockwise rotation of the South Caspian Basin. left-lateral strike-slip faulting is present along the ...  Read More

Tectonics
Geomorphic Signatures of Active tectonics in the Kashafrood drainage basin, NE Iran

Mohamad Reza Sajadian; Manouchehr Ghorashi; Elahe Javadi Mosavi; Mohsen Pourkermani; Mehran Arian

Volume 28, Issue 110 , December 2018, , Pages 299-306

Abstract
  Geomorphic indices of active tectonics are useful tools to analyze the influence of active tectonics. These indices have the advantage of being calculate from ArcGIS and remote sensing packages over large area as a reconnaissance tool to identify geomorphic anomalies possibly related to active tectonics. ...  Read More

Geomorphic Signatures of Active Tectonics in the Ajichai Drainage Basin NW Iran

Volume 28, Issue 109 , September 2018, , Pages 201-210

https://doi.org/10.22071/gsj.2018.80137

Abstract
  Geomorphic indices of active tectonics are useful tools to analyze of the active tectonics in a large area. These indices have the advantage of being calculate from the software and remote sensing packages over large area as a reconnaissance tool to identify geomorphic anomalies possibly related to active ...  Read More

Geomorphic Signatures of Active Tectonics in the Jarahi-Hendijan Drainage Basin (Marun-Zohreh Rivers) in South-West Iran

J Ehsani; M Arian; M Ghorashi

Volume 24, Issue 95 , June 2015, , Pages 211-219

https://doi.org/10.22071/gsj.2015.42047

Abstract
  This paper aims at evaluating relative active tectonics in the Jarahi-Hendijan drainage basin based on geomorphic indices. Indices used include: stream length-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), ratio of valley-floor width to valley height (Vf), index of drainage ...  Read More

Assessment of Quantitative Indices of Active Tectonics and Quantification of Relative Tectonic Activity at Mordaq-Chai Basin in South of Sahand Volcano; Northwest of Iran

M Sarhangi; A Solgi; A Sorbi; B Fayyazi; Sh Soltani

Volume 24, Issue 1393 , March 2015, , Pages 21-28

https://doi.org/10.22071/gsj.2015.43325

Abstract
  In this paper, the relative active tectonics of the Mordaq-Chai basin has been discussed according to the geomorphic indices using Global Mapper software. The calculated indices are as follows: stream length–gradient index (SL), hypsometric integral (Hi), ratio of valley floor width to valley height ...  Read More

https://doi.org/10.22071/gsj.2015.43417

Abstract
  Due to urban population growth in recent decades and the need for decentralization of cities with limited facilities and increasing marginalization in the larger cities, construction of new cities around large towns has been considered by decision makers to develop a plan to create new cities around ...  Read More

Influence of Structures on the Ghezel Ozan River

V. Hosseini toudeshki; M. Pourkermani; M. Arian; Kh. Khosrotehrani

Volume 21, Issue 81 , December 2011, , Pages 55-60

https://doi.org/10.22071/gsj.2011.54203

Abstract
  Rivers are the most important landforms on the ground whose analysis is known as a useful tool in tectonic surveys in several thousands to two million years ago. The Ghezel Ozan River, the longest river system in the country, has responded to tectonic deformation thoroughly. Detection and characterization ...  Read More
