abstract alluvial fans are the most striking phenomena o fluvial geomorphology . these forms are found in frount of mountains and pediments of arid and semiarid zones . alluvial fans are affected by climate changes and tectonics . occurring of tectonic events lead to reaction of alluvial fans . some of these reactions appear on dissection of alluvial fans and displacement of depocenters on allu...

The last decade has witnessed a resurrection of historical decadal geodetic rates provide a reasonable proxy for the long-term rates of plate motions (Donnellan et al., 1993; concepts and controversies concerning the evolution of landscapes in active tectonic regimes. New insights into Abdrakhmatov et al., 1996). If true, geodetic measurements provide an accurate snapshot of the tectonic forcin...

in central part of kopeh dagh there is an array of active right-lateral strike-slip faults that obliquely cut the range and produce offsets of several kilometers in the geomorphology and geological structure. geomorphic indices indicate the presence of differential uplifting in history of this area. tectonic activity of the study area is investigated by a large number of dem derived catchments ...

Debate about the relative roles of catastrophic v. continuous processes of landform evolution is as old as the discipline of Earth Science itself. Over the last 10 years or so, research in the Earth Sciences has focussed strongly on the Earth’s surface and particularly in terms of quantifying rates of processes. This research parallels developments in geomorphology and sedimentology in the quan...

Mapping seafloor geomorphology is a complex task requiring the integration of advanced cartographic technologies and high-resolution spatial data. This paper provides comparative geomorphological analysis Hellenic Trench (HT) Pliny (PT) located in Eastern Mediterranean Sea, southern Greece. These trenches were formed as result tectonic plate subduction Sea: northward motion African Arabian plat...
