Context: An indigenous river model BRAHMA-2D (Braided River Aid: Hydro-Morphological Analyzer) is  developed by the researchers of  IIT Guwahati along  with the Brahmaputra Board, Ministry of Jal Shakti.

IIT Guwahati researchers develop BRAHMA-2D model to understand flow of large braided rivers

• The model was successfully validated on the Brahmaputra River near Majuli Island.
• Findings  of the research were published in the ISH Journal of Hydraulic Engineering earning the   prestigious ‘ISH Jal Vigyan Puraskar’ (Best Paper in ISH Journal) 2023.

About BRAHMA-2D

• BRAHMA-2D is a quasi-3D river flow mathematical model. 
• Aim:  To study and  understand  the pace and movement of water at different depths inside a river and its circulation around a structure like a spur(installed to prevent river bank erosion) for large braided rivers like Brahmaputra.
• It has also been applied to understand habitat suitability of aquatic species, especially endangered species, based on the availability of required depth and flow velocity.
• Application: 
• • It will help understand how fast water moves at different depths in a river
  • It will provide valuable insights to field engineers to design sustainable hydraulic structures like Spurs, Revetment and other river bank protection measures.
  • The model will  help to design bioengineering methods for controlling river bank erosion.
