Abstract :

In many gravel-bed rivers, grain size changes decreased exponentially downstream and is mainly related to selective transport of clasts on the streambed and abrasion during transport. The Eshghabad-Sule basin with a surface area of about 81.365 Km2 is located at southwest of Quchan. The Eshghabad-Sule River is a braided river with gravel bar-bed. To understanding the grain size variation and effective factors in downstream fining analysed at 34 sites and the basis of them has been recognized 3 discontinuities and 4 sedimentary link . In this basin, the role of hydraulic sorting in comparative with abrasion is more effective in downstream fining of grain size.
