Both the kinematics and dynamics of topographic growth Tibetan Plateau remain debated, despite their significance for understanding evolution continental lithospheric geodynamics, climate, biodiversity in Asia. Topographic swath profiles reveal diversity high-elevation, low-relief plateau surfaces or “relict landscapes” throughout southeast Qiangtang, northeast Songpan-Garze-Yidun terranes east...

The river’s Geomorphology and its evaluation explore explanation of erosion, the longitudinal profile of the river bed and different forms of the rivers. Alvand River as the main river of the Alvand basin is located in Kermanshah Province W, Iran. The aim of this study is to investigate changes in longitudinal and longitudinal profiles of the river bed using mathematical functions and their rel...

The paper deals with the suitability of using the morphostructural analysis of the digital relief model (DRM) for compiling a geological map fault network focused on brittle failure of the rock mass. Attention is paid to the description of the procedure of interpreting the individual outputs of the morphometric methods selected. An important role in compiling the resulting network of the rock m...

The morphology of the Earth is a result of interactions between climate, tectonics, and geology and the investigation of neotectonics is one of the vital disciplines in Earth science, because the results of regional studies of active tectonics are significant for evaluating natural hazards as well as land use development and management in populated areas. In this regard neotectonic features of ...

-Introduction The Main Recent Fault (MRF) is a seismic structure on the northwestern boundary of the Zagros belt and southern border of the Sanandaj-Sirjan belt. This fault as a major strike-slip fault consists of several segments in the Zagros collision zone. The seismic activity of the southwestern segments is greater than the northwestern segments. Several earthquake events have occurred al...

Passive margin escarpments are extensively studied around the world, and understanding their evolution continues to present one of the more compelling interdisciplinary challenges tackled by earth scientists today. Escarpments reflect the morphotectonic development of passive margins and can separate regions with different climatic histories, but the inferred rapid rates of escarpment retreat h...

iran is located between two lithospheric plates (euroasia, arabian) and these two plates converge toward each other with a velocity of 25 mm/yr rate. shortening that produced from this convergence with makran subductin shows faulting and folding in zagros orogenic belt, alborz and kopedagh in north and sliding in sum strike slip faults with north-south trend in central iran. the nw-se trending ...

Tectonic geomorphology is part of Earth Sciences, which deal with study of the interaction of tectonic and geomorphology. In other words it studies the effective tectonic processes in forming and changing the landforms. Geomorphic and morphometric indicators are suitable tools to the morphotectonic analysis for different areas. These indicators are used as the base tool to identify and recognit...
