Study of active tectonic Osku chay basin with using indicators Geomorphic and evidence Geomorphologic

Changes bed rivers features a main river geomorphology are the most discussion. A river system is highly sensitive to changes in response to movement of the Earth's land, build geomorphologic features of structural changes with substrate and substrate changes be self. In this study, using digital elevation model (DEM) and satellite image and GIS (GIS to assess the potential of making a new field of application geomorphic changes of the river bed and geomorphological features will Osku chay. Using Digital Elevation Model DEM application environment Arcgis9.3 maps of slope, topography, and drainage sub-basins with different degrees estraler method will provide, for mapping faults from maps 1/100000 Geological Survey will use. After determining the direction of the flow channel and the number of them in any way, the parameters of the anomaly index will be used for Osku chay River. River sinuosity S, River defines the extent of the balance. Stream length gradient index river SL, tool for the study of tectonic geomorphology, Drainage basin asymmetry index channel AF, evaluation drainage in terms of tilting of tectonic, Ratio of valley floor width to valley height VF, indication of the valley floor of the V or U shape and the resulting impact tectonic activity in the formation of the valley V-shaped, shape index Basin BS show that represents a circular or elongate the basin, the influence of tectonic activity. data analysis of topographic, river systems region and geomorphologic evidence of field observations and by parameters on three major river osku chay basin and evaluate them using LAT indicators that the situation in the morphology sub basin geomorphology, a channels and the indicators in the study have an effective role in the end, according to surveys found that back as recently as 1990 of the study active tectonic zones
