بررسي رابطه بين پارامترهاي هندسي مياندرهاي رودخانه و ضريب سينوسيته

study of Relationship between River Meandersʹ Geometric Parameters and Sinuosity Factor

Running rivers in alluvial plains, always drawn to meandering process. In this paper, according to valley slope and river slope, the relationship between meandersʹ geometric parameters and sinuosity factor revealed. Based on the field data of Sistan River which is a meandering one, meanders geometric characteristics of this river were calculated and defined on the base of mathematical model. Finally, estimated results were compared with observed measurements in different reaches of Sistan River. This research demonstrates that acquired estimations and field measurements have a good correlation coefficient.
