Analysis of the Effects of Neotectonic Activity on the Longitudinal Profile (SL) of Garangoo Basin Located on the Eastern Slopes of Sahand Mountain

Tectonic factors, affect all segments of drainage systems. Drainage basins in longitudinal profiles, response to all changes of tectonic activity. All these responses are reflected in longitudinal profiles and erosion and depositional processes and also the flow pattern of rivers. Garangoo basin has undergone many types of tectonic activity in its history. These activities continue at present time. Traces of such activities can be found throughout the basin, especially on rivers beds. In this article relics of tectonic activity on longitudinal profiles have been investigated by the use of SL index with an emphasis on lithological and geological units. Results show that SL value is high, unlike lithological and geological units. These results also indicated that tectonic activity affected longitudinal profiles and changes in depositional and erosional processes.
