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 alluvial fans . The study area is located north Isfahan and North west Ardestan . The aim of this study is to identify Mooghar alluvial fan and consideration the role of effective factors in its segmentation and deformation using geomorphic indicators , geomorphologic evidence of active tectonics and visit field. These activites lead to displacement divergent centers and Depocenters, segmentation and succession of alluvial fan and creating new sequence of alluvial fan in the lower alluvial fan .
The new alluvial fan will be extend with continued erosion processes and perest alluvial fan will be divided into tow distinct parts of north and south
