Researchers from the Indian Institute of Technology-Guwahati (IIT-G) have developed a mathematical model to gauge the flow of large braided rivers like the Brahmaputra and help engineers to check river bank erosion.
Key points
- The indigenous river model named BRAHMA-2D (Braided River Aid: Hydro-Morphological Analyzer) may be helpful in the design of sustainable hydraulic structures like spurs, reverent and other river bank protection measures in order to check river bank erosion.
- River bank erosion is a serious issue in a flood-prone state like Assam, where the Brahmaputra and its tributaries create havoc during floods almost every year.
- BRAHMA-2D integrates a two-dimensional model of water movement with a theory about entropy, a measure of disorder or randomness.
- The BRAHMA-2D model was developed with the help of the Brahmaputra Board.
- It was successfully validated on the Brahmaputra river near Majuli Island.
- Majuli Island is the second largest freshwater river Island in the world, in Assam, which is prone to river bank erosion.
