Silt is defined as the granular material of size somewhere between sand and clay. Silt may occur as a soil or as sediment mixed with water as known as a suspended load in a body of water such as a river. It may also exist as soil deposited at the bottom of a water body. The natural process of the decay of organisms into the water can lead to the production of silt at the bottom of a river. Silt can be generated in the streams by mining, agriculture and other industries and sewage. Through these study an attempt has been made to record periodical observations of the river Manas, a tributary flowing into the Brahmaputra river, to record its different hydrodynamic properties viz. amount of silt carried, velocity during the period, discharge, cross-sectional properties etc. and to study its various aspects and then recommend some enhancing engineering solutions.
