The operational behaviour of a small river in respect to its length and channel width, channel morphology is one of the important aspects. The flow characteristic has a great importance in studying the behaviour of the river. River hydraulics which deals with the study of water of the river at motion or rest and another is river mechanics which the study of effects of forces on river water and produce the important aspects of channel morphology and channel flow characteristics. The flow behaviour of river water is a subject matter of river hydraulics which is very much influenced by the different properties of the water. According to Department of the U.S Army Corps of Engineers Washington, DC 20314-1000 River Hydraulics presents some basic principles and technical procedures for analysis of open channel flows in natural river systems. The main objectives are ¬¬¬¬- • To measure the velocity and discharge and their relationship between different channel geometry. • To observe the fluvio-geomorphological features in the study area.
