Siltation at a capital dredged site in Cochin harbour, SW coast of India

A capital dredging site at Cochin harbour was closely monitored for topogra phic variability and the role of natural processes in reprieving the scenar io. The textural characteristics points out the abundance of silt and clay (76-95%) and sparingly sand; on conduct of capital dredging, the prominence of sand is noteworthy. The bathymetric contours revealed the periodic chan ges on dredging and the resultant sedimentation leading to the gradual fill up of the dredged sites. The amount of dredging performed to reclaim the a djacent land was quantified using a computer aided analysis.
