Abstract

sediment transport from continents to oceans and seas via rivers is one of the most important processes regulating river-bank stabilization, soil formation, biogeochemical cycling of elements, crustal evolution and many other earth-related processes. Shahroud catchment is a part of Caspian Sea great drainage basin, located in North of Qazvin Province; its main tributaries are Alamoutrud and Taleghanrud rivers. As a structural point of view, the study area is part of Southern-Central Alborz structural zone which is mostly composed of Eocene volcanic units and Miocene terrigenous sedimentary rocks. In this research, water and sediment discharges (2013-2014 water year), grain size and mineralogical analysis of the sediment load were studied. Cyclic variation of discharge indicate a flood-dominated river; both water discharge and sediment load are controlled by the river tributaries and lithology of the catchment. This research shows (for the first time) that suspended load constitutes (mainly silt-size grains, composed of quartz, calcite, feldspar, muscovite/kaolinite) more than 99% of the sediment load. Bed-load materials are mainly volcanic-and carbonate-rock fragments. Erosion is the main process in upstream and transport/sedimentation is dominant in the river mid and downstream.
