36th foundation day of Brahmaputra Board celebrated
Staff Reporter
 GUWAHATI, Jan 13 - The Brahmaputra Board has undertaken an initiative to develop the technical skill of its young engineers. At a function, held on Thursday on the occasion of the 36th foundation day of the Board, four of its young engineers made admirable presentations giving an idea of the wind of change blowing in the autonomous body, which came into being on January 11, 1982. The function was presided over by Board vice chairman P M Scott.

Of these young engineers, Alemwati Long Kumar made a presentation on development of new agricultural land in Kynshi sub-basin of Meghalaya, engineer Partha Das made a presentation on power potential study of the Kynshi sub-basin, engineer Roshnara Begum made a presentation on the study of erosion-prone areas and identification of the locations for raised platforms using thematic maps, engineer Bhaskar Choudhury made a presentation on prioritisation of watersheds where soil conservation measures are required.

Alemwati Longkumar made his presentation on identification of new land that can be brought under cultivation in Kynshi valley sub-basin, basing on the slope maps and land use maps of the sub-basin. The approach used in this study is found to be unique, claimed the senior engineers of the Board.

Engineer Bhaskar Choudhury made a presentation on watershed prioritisation of Kynshi sub-basin using watershed erosion response model. He said construction of dams or barrage would reduce silt carried to the flood plains as observed in the Dhansiri sub-basin by the IIT Guwahati in their pilot project. Moreover, the eroded materials can be quantified basing on the additional parameters such as rainfall intensity etc., using universal soil loss equation (USLE).

In her presentation on use of satellite imagery and GIS technology for bank line vulnerability study and erosion and deposition areas, engineer Roushanara Begum said that satellite images from 1988 to 2015 were studied and basing on the comparative bank lines, vulnerability of the banks of the main stem Brahmaputra have been determined.

The study has also helped in determining the locations for the raised platforms to be built for the people of the flood-prone areas of the Brahmaputra valley and its sub-basin areas.

The above studies were prepared under the supervision of Board’s superintending engineer (p) DJ Borgohain.

Earlier, engineer Ranjit Deka, who underwent training in Japan on integrated water management under the auspices of the Japan International Cooperation Agency (JICA), said that contrary to the practice in Japan, people’s apprehensions are least considered by the planners in India while planning the irrigation projects.

The Japanese have taken the sewerage system even to their rural areas and they have been developing manures for their farmlands using the treated sewage.

The Japanese have also been able to build the tallest earthquake-resistant tower – the 2,080 feet-high Tokyo Skytree – on earth, despite the fact that their country is one of the most susceptible one to earthquakes. Significantly, the Japanese have also built dams on some of their rivers, said Deka.
