Entropy and Energy Dissipation of a Braided River System

AbstractThe randomness in morphology of the Brahmaputra River is very common because of its high flow variability and erodible banks. The river is severely braided with no permanent bank line and varies its width by 1.2km to 18km. During the monsoon season it follows several tortuous braided paths to dissipate its enormous energy. The river changes its braided planform in response to seasonal water and sediment waves and makes its morphology extremely complex. This paper aims to link the braided planform disorderness as a measure of entropy with the energy dissipated by the braided river system to study the river behaviour for various flood waves
