A Study on the Relationship between Siltation and Flow Parameter of a Typical Alluvial River - Studied Open Channel Flow Bhogdoi River

Abstract

The tendency of a river to change its course is the common feature of a river. This causes various problem to agricultural land, habitation, hydraulic structure etc located on the river banks. Soil erosion is one of the major threats to the society and it affects the economy of the state. It occurs when grains or assembly of grains are removed from the bank face by the flow. Due to strong forces of lift and drag exerted on the bank by flow, it detaches and removes soil from the intact soil. In our state as the mighty Brahmaputra river passes through the heart of Assam, therefore the affect of soil erosion is very horrible. From the earlier time various method are taken to eliminate soil erosion. The aim of this project is to record periodical observation of a tributary flowing into the river Brahmaputra to check its different properties i.e. the amount of silt carried, velocity during the period, discharge of the section, cross sectional properties and to study its various aspects to enhance some solution
