Quantitative indices to measure unit channel bar location: a theoretical and empirical study

Abstract

Each and every channel bar possesses a specific location within a channel. The terms mid-channel bar, bank attached bar are lacking quantitative definition. The intention of formulation of the two indices is to measure the channel bar location on strict quantitative basis. These indices will precisely determine the location of the mid-channel bar and bank attached bar. The first measure will determine the physical location, considering only distance and the second one will be for determining virtual or relative location considering both distance and hydrologic parameters mainly discharge.

Key Word: Physical location; Virtual location, Mid-channel bar, Bank attached bar
