Abstract

Land reclamation was proposed by a private realty developer in East India along River Hooghly to reclaim the land lost due to erosion occurred by tidal courses along the river. The project site is situated at Raichak, 50 km east of Kolkata. The total length of the bank proposed for reclamation was around 500 m. The initial phase of the project involved reclamation of eroded land and armour protection of the newly formed bank slopes on river side and thereafter to proceed develop the property. Geotextile tubes were selected for its technical efficacy and cost effectiveness besides quicker construction. Geotextile tubes are inflated using sand slurry and the quality of sand is very important to determine the shape of the tube and inflated height. This paper focuses on critical engineering aspects associated with design of the geotextile tube, methodology to pump the tubes in a successful manner while using fine grained soil fills usually available from the alluvial deposits of the Gangetic plane.
