Title

RECOGNITION OF EFFECTIVE PROCESS ON SEDIMENTARY LINK AND TEXTURAL VARIATIONS IN FLUVIAL SEDIMENTS OF BIDVAZ DRAINAGE BASIN-EAST ESFARAYEN

Pages

  75-85

Abstract

 The Bidvaz Watershed is located east of Esfarayen in northern Khorasan Province. Bidvaz is the major river in this watershed with two tributaries (Darparchin and Sorkh-Ghaleh). These rivers have gravelly beds with braided patterns. For analysis of SEDIMENTARY LINK and recognition of fining factors, surface samples from channels have been collected from Bidvaz and its tributaries. Grain size analysis shows that the SEDIMENTARY LINK does not show a uniform trend, especially about in two tributaries and have broken in two pointes along the river. SEDIMENTARY LINK shows a relatively uniform trend in the BIDVAZ RIVER which is the longest one in this basin. It is shown that the (1) sudden changes in SLOPE GRADIENT, and (2) tributaries entrance with high course of sediment yield are the main factors that change the SEDIMENTARY LINK. Analysis of SEDIMENTARY LINK, grains size variations and textural parameters (sorting, skewness and kurtosis) show that the "selective transport" is the most important process that controls the DOWNSTREAM FINING in grain size. Because of the abundance of grains with diameter larger than 16 mm, it can be concluded that SELECTIVE SORTING depends on the grain size increased in upper parts of each subtrend. We hope that the results of this research can be used in similar basin to predict erosion.
