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...

Paractinolaimus sahandi n. sp., found in wet soil samples collected from the rhizosphere of grasses of Sahand Mountains, Iran, is described. This new species is characterized by its long body (3.5-4.7 mm), high a value (74.5-88.5), anterior location of posterior subventral nuclei, occupying 62.5-68.0% of glandularium distance, the presence of 1-4 pre- and 1-3 post-vulval papillae and numerous t...

because of the presence of special properties in semi arid catchment, these areas are suitable for drought events. the responses of these areas to drought events are in the form of the disappearance of plant cover on surfaces slopes, intensive erosion or landslide occurrence on side of rivers’ course. azarshahr catchment (situated in 37ëš 36′ to 37ëš 49′ n and 44ëš 20′ to 45ëš 49′ e) ...
