Abstract

One of the most important engineering issues which greatly affects human activities is the Meandering of revers. Accordingly, studying this phenomenon in rivers is essential for accurate identification, identification of the resulting hazards, coping with them and optimal exploitation of natural resources. The purpose of this research is to investigate the characteristics of the riverside runways of the Gadar River route. The purpose of this study is to investigate the characteristics of the riverside meanderings of the Gadar River route. In order to achieve this goal, considering the size of the area under study, the use of satellite imagery and geographic information systems are considered as essential tools for processing. Based on this, satellite imagery ETM + was used for the years 2000 and 2012 and the IRS. The results showed that during the two surveys, the trend of river changes in the triple intervals is completely different. So that the first interval is the highest and the third is the least change over the two periods. The values of the central angle and the bending coefficient also indicate that, in all the intervals, the variation of the bending coefficient and the central angle, with the exception of a relatively small proportion in the mountainous regions, confirms the existence of roughly similar arcs along the path.
