Abstract This paper presents a robust approach using artificial neural networks in the form of a Self Organizing Map (SOM) as a semi-automatic method for analysis and identification of morphometric features in two completely different environments, the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) in a complex mountainous humid area and Yardangs in Lut Desert, Iran, a hyper...

The current study is designed to analyze theslope stability of Haditha damwhich an earth-fill dam constructed on the Euphrates River in middle-west Iraq. Finite element modeling was used present combined seepage and post-earthquake slope earth dam. maximum water level a steady case considered evaluate seepage. - Three different levels (maximum, normal, minimum) were applied, nine equilibrium li...

Excavated geo-relics are vulnerable to damage by natural processes. The aim of this study is contribute the establishment a technical framework for preservation openly exhibited geo-relics. This also examines an geo-relic in Japan, which has experienced surface deformation soft soil layer due water infiltration. numerically investigated performing seepage-deformation analyses based on unsaturat...

Climate change is already being felt in Europe, unequivocally affecting the regions’ geo-structures. Concern over this rising, as reflected increasing number of studies on subject. However, majority these focused only slopes and a limited geographical scope. In paper, we attempted to provide broader picture potential climate impacts geo-structures Europe by gathering collective view geo-enginee...
