The Brahmaputra is one of the world's largest rivers, ranking fifth in
terms of average discharge. Therefore, to dissipate it's enormous
energy, it is severely braided with multiple complex pathways. Although,
this river is typically classified as a braided river, however due to
its multi-channel properties over alluvial plains, it has recently been
classified as an anastomosing river. Additionally, the morphology of the
Brahmaputra River is random in nature due to its high flow variability
and bank erodibility. It's anastomosing planform varies in response to
seasonal water and sediment waves, resulting in an extremely complex
morphology. The goal of this study is to investigate the anastomosing
planform entropy of the Brahmaputra river as a measure of disorder and
how it relates to the energy expenditure by the river systems on
alluvial landscape.
