abstract a mountain glacier, when it occupies a river valley, immediately begins to change the cross-section and profile of that valley. river valleys in mountain areas tends to have v-shaped profiles. glaciers work to widen as well as deepen their valleys and the typical cross-section of a glacial valley is u-shaped. the u-shaped glacial valley is one of the most characteristic of glacial land...

the goal of this article is to study the shimashki potteries in the saymarreh valley. archaeological surveys conducted in the saymarreh valley shows that the painted pottery tradition of godin iii has become prevalent in the valley during the bronze age and only once, development of this pottery tradition had cracked. this event took place in the phase of godin iii4, which we relate it to the i...

in this paper, an advanced formulation of the spectral finite element method (sfem) is presented and applied in order to carry out site response analysis of 2d topographic structures subjected to vertically propagating incident in-plane waves in time-domain. the accuracy, efficiency and applicability of the formulation are demonstrated by solving some wave scattering examples. a numerical param...
