Abstract

Abstract: Jagin river with the formation of a relatively large delta arrive to the Oman Sea. In this paper rely on results based on field survey and index of geomorphic, has been studied morphology and riverbed changes. The purpose of this study is recognition impact of neotectonic in jagin river drainage network. Morphology and behaviour of drainage network, to change from neotectonic is sensitive. Considering the evidence as changes multiple paths in different time periods, crossing the fault line, broad and narrow riverbed, It seems that under the influence of neotectonic active in the region. For achieving results, Geodynamic data, Index geomorphic, Time of Concentration, topographic and geologic maps, aerial photos and satellite images of this area as the main reaserch tools and conceptual and model techniques were used. Then the data through field works by GIS (ArcGIS&ilwis) analysis and effect of tectonic analysed. In this view, between redirected drainage and morphological feature and neotectonic affects has been relationship. Results indicate continuity of the last neotectonic activity in the Study area and displacement Amount of activity is not the same everywhere, and movement is towards the north eastern region. The findings of this research can be useful for the study of impact of neotectonic on riverbed changes.
