The Aladağlar is a mountain range located in the central Taurus Mountains (37°45′ N, 35°15′ E) along Mediterranean coast of Turkey, dominated by geomorphic features intervened karstic and glacial landscapes. Aladağlar, also known as Alps one most popular places for mountaineering. Here, we present comprehensive geomorphological map mountain. Despite increased recent research, understanding spat...

every year, a considerable portion of the national budget specifies to reconstruct the properties which have been destroyed during natural disasters in iran. recognition of vulnerable sites to natural disasters can reduce the probable damages. the most important point in designing railway tracks is to join stations in the least possible time. so, the railway track is meant to cross lots of vall...

Quaternary climatic factors have played a significant role in population divergence and demography. Here we investigated the phylogeography of Osteomeles schwerinae, a dominant riparian plant species of the hot/warm-dry river valleys of the Hengduan Mountains (HDM), Qinling Mountains (QLM) and Yunnan-Guizhou Plateau (YGP). Three chloroplast DNA (cpDNA) regions (trnD-trnT, psbD-trnT, petL-psbE),...

The transverse canyon is a V-shaped, fluvial-genetic canyon, secondary valley formed by drainage crossing tectonically uplifted mountain. Paleotopography of the vital to connection and river capture, offering insight into processes that link large-scale systems, analyzing paleodrainage patterns, recreating headward erosion. Notably, modern paleotopographic reconstruction methods are usually lim...

21 Ž . Concentrations of cosmogenic Ne Ne measured in quartz have been used to estimate long-term rates of denudation c for contrasting landscape components in the Dry Valleys area of the Transantarctic Mountains, southern Victoria Land, Antarctica. Samples of Beacon Supergroup sandstones and granitic basement were collected from two contrasting landscape elements—low-relief, high-elevation sur...
