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 changes on dredging and the resultant sedimentation leading to the gradual fill up of the dredged sites. The amount of dredging performed to reclaim the adjacent land was quantified using a computer aided <span style="font-size:14.0pt;line-height:115%;font-family:" times="" new="" roman";="" mso-fareast-font-family:hiddenhorzocr;color:black;mso-ansi-language:en-in;="" mso-fareast-language:en-in;mso-bidi-language:hi"="" lang="EN-IN">analysis.</span></span>
