Abstract

River sedimentology provides significant basic data for river engineering projects (sediment transport and channel stabilit.( Most of these data are collected after careful study of bedform, texture and facies analysis along with architectural elements (Hey et al., 2015). Downstream grain size changes are complex in a gravelly bed river and often do not follow a simple sediment graft model. The processes affecting the sediment degradation process in rivers are selective sorting, wear and sedimentation rate of lithological units of the catchment (Ruset, 1978). Mianroud river is located in the southeast of Iran, which is one of the very low rainfall areas with an average annual rainfall of 63.6 mm and has a dry climate. Severe and short-term showers play a very important role in the occurrence of large floods in the Mianrud catchment area. In this area, factors such as diversity of different faults, geomorphic controls (river flow, basin slope, ...), hydraulics (water discharge), and sedimentology (sediment production, transfer and re-sedimentation) control the main parameters of the river (Sin Ciana and Pasternak, 2017.( This paper presents the textural changes of sediments, rock facies and architectural elements and sediment model in a rugged mountain river.
