Sponsored Research Projects:

• A collaborative project with Brahmaputra Board titled “Mathematical Model of Brahmaputra River Considering Impact of Climate Change” has been started. This project proposal was initiated by B.P.Chaliha Chair professor immediately after taking responsibility of the chair. After long pursuance finally the MoU has been signed in Sept. 2014 between Brahmaputra and IIT Guwahati to take up this ever needed project.


• The Chair along with Dr. R.K.Bhattacharjya, Associate Prof, CE Dept., has received a DST project on “A numerical Modelling Based Study for Assessing Quality of Ground Water of Bharalu River Basin of Guwahati City” [received on Sept. 2014]


• The Chair along with Dr. M.K.Goya, Assistant Prof, CE Dept., has received a project on “An Integrated Approach for Snowmelt Hydrological Modelling at Downstream of Sikkim Glaciers” [received on Sept. 2014]


• A project titled “Climatic Data Collection from Tea Garden and Other Sources of Northeast India for Climate Change Study has been completed on March 2012”. The basic objective of this project was to collect climatic data and to understand various water related problems faced by different organizations and community. As a part of this project solutions were suggested to various tea gardens to mitigate their water related problem. It is to be noted that understanding possible impact of climate change, several gardens has implemented the idea of rain water harvesting for better management of water and could get immediate benefit in production.


• As evaluating performance of hydraulic structure in Brahmaputra Basin under the impact of climate change was considered as one of the objectives of B.P. Chaliha Chair, Pending comprehensive modelling of Brahmaputra River, B.P. Chaliha Chair started the project Mathematical Modeling of Main-Stem Brahmaputra for Evaluating Effect of Climate Change on Hydraulic Structure. To have optimal combination of river training work for various purposes including protection of river-bank from erosion a 2D linked simulation optimization model has already been developed and its capability has been tested in erosion affected reach of Brahmaputra River. As an outcome of this project the Chair along with his researchers has made significant progress in developing first ever Indian Model for River Modelling titled Braided River Aid: Hydro-Morphological Analyzer (BRAHMA). Hydrodynamic component of this model has already been developed and successfully run and further research is going on in the morphological modelling.


• To evaluate the need of regular updating of Bathymetry for flow simulation, a sub-project entitled effect of “Bathymetric Change on Flow Profile of River Brahmaputra: Scope of Modeling” has been completed. The study has shown that bathymetric change can have significant effect on the flood scenario. Details of this work have been given in the report submitted to climate Change Directorate of CWC, MoWR


• B.P.Chaliha Chair and his research team has spent considerable amount of time and effort in preparing two major project proposals on Basin level study to evaluate impact of climate change on water resources. These are 1) Basin Level Study on Impact of Climate Change on Brahmaputra and Barak Basin, 2) Basin Level Study on Impact of Climate Change on other Rivers Flowing to Bangladesh and Myanmar”. These projects were prepared on request of from MoWR as collaborative projects of IIT Guwahati, NIT Silchar and NERIST.
