eshtehard aquifers are shoor river's catchment basin and water potential in different areas. eshtehard aquifers, because of the diversity of geological formations and structures have different quality and quantity. this paper aims, to determine the relationship between quantitative and qualitative characteristics of water resources with the lithology and structural geological features of t...

In the present work, the Differential SAR Interferometry (DInSAR) technique has been applied to study the surface movements affecting the sedimentary basin of Cassino municipality. Two datasets of SAR images, provided by ERS 1-2 and Envisat missions, have been acquired from 1992 to 2010. Such datasets have been processed independently each other and with different techniques nevertheless provid...

the kalut-e-ashrafa area is located in the north-east of ardakan area in central iran, yazd province. this area promises copper mineralization. the most of the minerals in this study area are silica-rich veins and veinlets. therefore, in order to identify geological formations with silica zones and to determine potential mineralization areas, aster images and remote sensing methods were used. a...

Geological structures are by nature inaccessible to direct observation. This can cause difficulties in applications where a spatially explicit representation of such structures is required, in particular when modelling fluid migration in geological formations. An increasing trend in recent years has been to use analogs to palliate this lack of knowledge, i.e., exploiting the spatial information...

Stochastic surface models are useful for analyzing in situ roughness profiles and synthetic aperture radar (SAR) images of geological terrain. In this paper, two different surface models are discussed: surfaces with a stationary random roughness (conventional model) and surfaces with a power-law roughness spectrum (fractal model). In the former case, it must be considered that for short profile...

in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...

The development of engineering activities involving shales such as the extraction of shale gas and shale oil, the nuclear waste geological storage and the sequestration of CO2, has led to an increasing interest toward the geomechanical behaviour of this geomaterial. In the context of such engineering applications, a deep understanding of the hydro-mechanical behaviour of shales is of primary si...

The remains of the natural and human activities in some parts of the earth register as geopark. Actually, geopark is one or more geological phenomenon which is important from ecology, history, culture and archeological view. The aim of the geotourism description in an area and creating a geopark is trying to keep the earth's inheritance and locality the economic of the area. Iran with an old hi...

The heterogeneity of natural geological formations has a major impact in the contamination of groundwater by migration of pollutants. In order to get an asymptotic behavior of the solute dispersion, numerical simultations require large scale computations. We have developed a fully parallel software, where the transport model is an original parallel particke tracker. Our performance results on a...
