ABSTRACT: Alluvial fans are grouped
in buildings which can provide important evidence of tectonic and climatic
changes [1],
Shahrud-Bastam area as structure point is located between Eastern Alborz
structural zones in the north and central Iran structural zone in the south. In
this study, we have measured 16 indicators morphotectonic on 79 alluvial fans and 46 catchments, according
to the results of the measurements of morphometric parameters of alluvial
basins and watershed, we find out that Qods-Armiyan’s fault zone has the most of tectonic
activity between Tazareh and Shahrud fault regions. According to the index As,
the development of alluvial fans often has a direct relationship with Level
rise, which has a particular importance in the study field.
