The main objective of this study is destined to combine the Analytical Hierarchy Process (AHP), Weight Evidence (WOE), Logistic Regression (LR) methods and geographic information system (GIS) predict landslide susceptibility Echorfa region (northwestern Algeria). Nine factors such as slope, aspect, lithology, distance faults, lineaments density, streams, precipitations, land use altitude are in...

gully erosion constitutes a major problem in natural resources management and soil conservation, which causes severe land degradation in arid and semi-arid areas. therefore, determination of gully prone area and identification of gully conditioning factors can help to managers and decision makers to reduce the hazard of gully erosion. the aim of this study is to predictthe gully erosion suscept...

A stochastic Bayesian approach for combining well logs and geophysical surveys for enhancing subsurface characterization is presented. The main challenge we face is in creating the bridge to link between ambiguously related geophysical surveys and well data. The second challenge is imposed by the disparity between the scale of the geophysical survey and the scale of the well logs. Our approach ...

This was a study of subglacial deformation till genesis from a modern temperate glacier, at Sk alafellsj€ okull, Iceland. Detailed microscale properties of till samples (from Scanning Electron Microscope [SEM] and thin section analysis) were examined from a glacial site with in situ subglacial process monitoring and an exposed subglacial surface in the foreland. Two lithofacies were examined, a...

considering the fact that entrepreneurship can be taught and the emergence of entrepreneurship education, there is a stronger need for newer ways of education such as electronic entrepreneurship education. this research is conducted to identify the success factors of electronic entrepreneurship education in the entrepreneurship faculty of tehran university using a qualitative and quantitative a...

The Fatha Formation, formerly known as the Lower Fars was deposited in a shallow basin, southern Iraq during Middle Miocene. By using description of cores, we found large heterogeneity lithology; contains mixing limestones, mudstone, marl, marly limestone, sandstone, and gypsum, or anhydrite. In this study, Formation divided into three main units according to lithofacies, namely, marl-anhydrite...

avo as a known methodology is used to identify fluid type and reservoir lithology in subsurface exploration. method discussed in this paper, consists of three stages, including: direct modeling, inverse modeling and cross plot interpretation. by direct modeling we can clarify lithology or fluid dependent attributes. analysis performed using both p-p and p-sv attributes. inverse modeling deals w...
