Analysis of the Neo-tectonic activity of the Gechi Darasi Basin catchment using geomorphic indices

Tectonics are dynamic factors that have longitudinal profiles of rivers, especially watersheds are affected.. These factors led to a change in the longitudinal profile of rivers and the erosion and deposition process, thereby changing the pattern of investment flows into rivers. The purpose of this study is to investigate active tectonic basin Gechi Darasi data by geological, geomorphological and observation field, hypsometric curve by using indicators, hypsometric integral, drainage basin asymmetry, the longitudinal gradient of the river, the sine of the mountain front, the width Reverse topographic drainage basin above the valley floor and valley symmetry in this field. According to the results of this study indicate Hypsvmtry integral curves Hypsvmtry young field of erosion cycle and 15 sections and transects to assess VF index specified. Index changes VF (which is equal to 1.2) reflect tectonic activity is active. In addition, SL index is calculated for the basin. Establish fault tolerance on the rock of considerable height difference Gechi Darasi River longitudinal profiles and SL index is a significant change. The basin has a lot of sinus (Smf) in the region of 1.3 is equal to the ratio of the width to the height of the bed of the valley floor is a very large difference. Drainage basin asymmetry index (AF) is equal to 57.45. The topographic indexes with the reversed polarity index (value 0.21) indicate tectonic activities in the region are high.
