Mohamad Khanehbad[1]* Niloufar Hajian[2] Reza Moussavi Harami[3] Asadullah Mahboubi[4] Abstract Farub Roman River with a length of about 19 km in the Northeast Neyshabur is a perennial river. To determine the sedimentary parameters in this river, 55 samples were taken from the main channel of this river and then granulumetry analysis and statistical parameters were calculated. The mean sorting of sediments is1.609phi (Poorly sorted) and skewness is 0.393 (Strongly fine skewed) and Kurtosis is 0.965 (Mesokurtic). This river is of braided type with load gravel bed. In this river, four sedimentary discontinuities and five sedimentary links are detected. Grain form of the river is in the range of very bladed, and major of deposits are in gravel range. Facies that could be identified in this river are: Gci (grain supported gravel), Gmm (matrix supported Gravel), Gmg (graded and matrix supported Gravel), Gh (grain supported gravel with horizontal bedding)) for gravelly facies, sand with horizontal bedding (Sh) for sandy facies and massive mud (Fm) for muddy facies. The facies formed in these structural elements are such as Channel (CH), Gravity flow deposits (SG), Gravel bars and Bed forms (GB) and Fine grain clastic deposits (FF). Based on the results, sedimentary model for Farub Ruman River is of braded type with loaded gravel bed.
