Investigation of Gezel Ozan River Pattern Changes by Fractal Geometry

Researchers of river Geomorphology science are seeking new ways to check River Geomorphology and its pattern changes always. Fractal geometry is one of the new methods that can be used in Geomorphology of river science. The main importance of fractal geometry is presentation of the model and mathematical description for complex shapes that in nature can provide. The goal of this research is Fractal analysis of Gezel Ozan River changes between routes of Miyaneh to Zanjan. For this purpose was used satellite images of periods 2000, 2004 Sensor ETM + and 2007 sensor IRS. For Fractal analysis the studied route was divided into three periodsthat each period is different in terms of morphological characteristics. For determine of fractal dimensions was used from box-counting method. The survey results showed that the first interval (interval arterial) has had the highest changes and the second range (Mid-range Mountain) has had the lowest changes and third period (mountain range) has had an intermediate case.
