Identification of sediment harvesting areas in west wind erosion center of Tehran Province (Case Study: Malard County)

Mahin Hanifapour; Gholamreza Zehtabian; Hasan Ahmadi; Aliakbar Nazari Samani; Hassan Khosravi

Volume 29, Issue 2 , July 2022, , Pages 186-195

Abstract
        Wind erosion and dust storms are one of the natural disasters that are increasingly facing the arid and desert areas of central Iran. Improper management in natural resources has also had a high impact on this phenomenon. One of the basic principles of controlling and combating ...  Read More

Detection of dust storm paths using numerical models and satellite images (Case Study: Isfahan Province)

Mehdi jafari; Gholamreza Zehtabian; Hasan Ahmadi; Tayebeh mesbahzadeh; Ali Akbar Norouzi

Volume 26, Issue 1 , June 2019, , Pages 29-39

Abstract
  Dust pollution is one of the most important environmental challenges in recent years in the Middle East and Iran. It is important to monitor and control the quality of dust particles in a wider range using the methods that are more cost effective and less costly. The present study aims to use numerical ...  Read More

Analysis and zoning of wind energy based on sand drift potential in Qom-Tehran railway

Mohammadreza Rahdari; Hasan Ahmadi; Ali Tavili; Mohammad Jafari; Aliakbar Nazari Samani; mohammad khosroshahi; Shahrooz Sharifi

Volume 26, Issue 1 , June 2019, , Pages 226-240

Abstract
  Due to vast desert area in Iran, wind regime studies are important for the railway safe design as well as aeolian sediment transport. In this study wind regime and sand drift potential (DP) were calculated with Fryberger method in nine meteorological stations located near to the Qom –Tehran railway ...  Read More

Quantitative Modeling of Dunefields High and Space Using Geomorphometric Studies in Central Deserts of Iran

ali nazari; hamidreza abbasi; hasan ahmadi; mohammadreza rahdari

Volume 24, Issue 1 , May 2017, , Pages 210-223

Abstract
  This research was aimed to modeling the height and distance of sand dunes in central deserts of Iran (Kashan Erg and Jen Erg) as well as their classification.  Results of identifying sand dunes in the study areas showed that there were considerable variations in formation of sand dunes in central ...  Read More

Investigation on intensity of geology-geomorphology and soil criteria on desertification of Segzi plain

Saeedeh Nateghi; Gholam reza Zehtabian; Hasan Ahmadi

Volume 19, Issue 4 , March 2013, , Pages 590-600

Abstract
  Segzi plain is one of the most critical areas of the province in terms of the extent and severity of desertification process. This area has a special strategic position due to the industrial centers, Shahid Babaee airport, Shahid Beheshti International Airport, railroads, transit road of Bandar Abbas- ...  Read More

Investigation on volume and statistical parameters of sedimentology in upstream channels of Tehran - Qazvin Highway located in Khor-Sefidarak Basin.

Sadat Feiznia; Hasan Ahmadi; Soheila Youneszadeh Jalili; Mohammad Ali Fatahi ardakani; Marzeiyeh Abbasi

Volume 19, Issue 2 , September 2012, , Pages 244-263

Abstract
  Differences in particle size through downstream is a proper tool to understand evolution steps and river channel morphological changes, including sediment transport, channel migration context, the risk of floods and human activities. The present study investigated sediment deposits in upper rangelands ...  Read More

Evapotranspiration Estimation Using Climatic Data, Plant Characteristics and Cropwat 8.0 Software (Case Study: Steppic Region of MarkaziProvince, Roodshore Station)

Ali Ehsani; Hosein Arzani; Mahdi Farahpur; Hassan Ahmadi; Mohammad Jafari; Mortezah Akbarzadeh

Volume 19, Issue 1 , June 2012, , Pages 1-16

Abstract
  In this study, potential and actual evapotranspiration were estimated by Penman- Matis using climatic data of Saveh Station, and plant and soil characteristics were estimated by Cropwat 8.0 software. Our results showed that potential evapotranspiration in growing season was 6.16 times greater than the ...  Read More

Sand sources determination based on granolometry of surface soils or sediment (sediment generation potential)

Naser Mashhadi; Hasan Ahmadi

Volume 17, Issue 4 , November 2011, , Pages 499-517

Abstract
  The results of wind dynamic are transport of soil or sediment particles and subsequently evolution of desert landforms according to the intensity of either erosion or sedimentation process.Geology, geomorphology and climatology conditions of the Khartouran region create a special situation on the closed ...  Read More

Evaluation of sediment estimation of E.P.M and P.S.I.A.C models using geomorphology method (case study: Dehnamak Watershed)

Hasan Ahmadi; Ali asghar Mohammadi

Volume 17, Issue 3 , October 2010, , Pages 340-352

Abstract
  Since wind or water erosion is a phenomenon that causes waste of soil, it is necessary to combat soil erosion through soil conservation practices.  Currently, some models have been developed to estimate erosion which should be examined with other existing models in different regions. In this study, ...  Read More

Application of Analytical Hierarchy Process (AHP) in assessment of de-desertification alternatives Case study: Khezrabad region, Yazd province

Mohammad hassan Sadeghi Ravesh; Hassan Ahmadi; Gholam reza Zehtabian; Mohammad Tahmores

Volume 17, Issue 1 , September 2010, , Pages 35-50

Abstract
  With respect to importance of desertification issue and complication of this phenomenon because of interaction of different and numerous variables during the time, paying effective attention to the optimum alternatives is vital for prevention of de-desertification or rehabilitation and improvement of ...  Read More
