Pontoon bridges, sluice gates and aerostats will be used to plug vulnerable patches along a 60-km long stretch in riverine areas on the Indo-Bangla border in Assam, which the government plans to seal shut by June 2017.
The 60.7 km border is to be plugged using smart technology and non-physical barriers. Pontoon bridges are proposed to be laid in riverine areas so that Border Security Force (BSF) personnel can monitor movement across rivers.
High resolution cameras will tighten vigil on the porous border, which are used for infiltration and smuggling of cattle and drugs. BSF has constituted a team for the purpose with senior Assam government officials and experts from institutions like IITs.
It has also been proposed to build over two dozen sluice gates on rivers to control the flow of water and check the changing course of the Brahmaputra during monsoon. "Every year when Brahmaputra changes course, BSF posts get hit and some get destroyed. Sluice gates can solve this," an official said.
A smart control room will be created to receive surveillance feeds and relay it up to Guwahati and to the BSF headquarters in Delhi, the official further added. The 284 km Indo-Bangla border in Assam, 224 km is fenced. India shares a 4,096-km frontier with Bangladesh.
