Volume 29, Issue 114 , December 2019, , Pages 251-258

http://dx.doi.org/10.22071/gsj.2018.113987.1367

Abstract
  The arid and semi-arid climate with a low rainfall along with the population growth has been lead to overexertion from groundwater resources over recent two decades in Iran. This over-extraction has been led to the significant groundwater depletion and water level decline in most parts of Iran as well ...  Read More

Volume 28, Issue 109 , September 2018, , Pages 3-6

http://dx.doi.org/10.22071/gsj.2017.97965.1253

Abstract
  Abstract In the urban tunneling project, one of the most important parameters to be considered is the subsidence level. Metro tunnels are one of the most important urban transportation infrastructures. Due to shallow depth of drilling, the most important factors to prevent the maximum subsidence and ...  Read More

M Mirzaei Souzani; A Shahidi; R Ramezani; F Alizadeh Sevari

Volume 24, Issue 95 , June 2015, , Pages 39-48

http://dx.doi.org/10.22071/gsj.2015.41783

Abstract
  In order to survey the extensional forces dominated in central Alborz since Late Triassic (Norian) to Middle Jurassic (Early-Bajocian), synsedimentary normal and strike-slip fault systems in Balladeh valley which contains significant distribution of Shemshak Group have been studied. Analysis of σ3 ...  Read More

Volume 22, Issue 85 , December 2013, , Pages 105-114

http://dx.doi.org/10.22071/gsj.2012.54026

Abstract
  A large area in Hashtgerd plain, in southwest of Tehran, is subject to the land subsidence induced by overexploitation of groundwater. In this paper, in order to study the subsidence SAR interferometry (InSAR) and global positioning system (GPS) are used. The small baseline subset (SBAS) algorithm is ...  Read More

5. Subsidence Monitoring in Mashhad and Neyshabour area based on Change of Curvature Analysis Method Using Displacement Field from GPS Observations

Volume 21, Issue 82 , December 2011, , Pages 133-138

http://dx.doi.org/10.22071/gsj.2011.54449

Abstract
  The methodology of geometrical modeling of the earth surface deformation [surface deformation tensor of the first kind (tensor of strain), linearized surface rotation tensor, and surface deformation tensor of the second kind (tensor of change of curvature)] is done using different kind of space geodetic ...  Read More

6. Tectonic Evolution of the Alborz in Mesozoic and Cenozoic

Volume 21, Issue 81 , December 2011, , Pages 201-216

http://dx.doi.org/10.22071/gsj.2011.54384

Abstract
  In northern Iran the Eo-Cimmerian orogeny resulting from this collision is associated with a regional unconformity and a major change in sedimentation. From Norian to middle Bajocian (Shemshak group), 030° trending extension is indicated by syndepositional normal faults. We assign this extensional ...  Read More

7. Investigation on Confined Aquifer & its Role on Subsidence Occurrence in Hashtgerd Plain

Volume 20, Issue 79 , January 2011, , Pages 137-142

http://dx.doi.org/10.22071/gsj.2011.55058

Abstract
  Based on recent research by geological survey of Iran (GSI), an extensive subsidence area was observed in Hashtgerd plain (Tehran province). The geographical position of this area is 35° 47' 45" to 35° 03' 05" N and 50° 29' 05" to 50° 54' 28" E. The maximum and mean rates of this subsidence ...  Read More

http://dx.doi.org/10.22071/gsj.2010.55338

Abstract
  Mud volcanoes are one of the interesting phenomenons that many researchers in oil field, plate tectonics and geotourism consider the most. In this regard there are many studies in the other countries, especially those which have this phenomenon and published many articles. This article is the output ...  Read More

9. Studying Yazd Subsidence Using InSAR and Precise Leveling

Volume 20, Issue 77 , January 2010, , Pages 157-164

http://dx.doi.org/10.22071/gsj.2010.55368

Abstract
  Blemish of subsidence and land ruptures such as destroying aquifer systems, damaging structures and disordering water main, are usually irreparable and expensive. One of the regions with a high rate subsidence in Iran is the Yazd-Ardakan plain that subsides with a maximum rate of 12 cm per year based ...  Read More
