As may be observed from the above table, the cross section near the outfall had a maximum area of<br />
929 sq. meter (1966, probably as a consequence of dredging the channel), compared to 696 sq.<br />
meter according to the latest available data of 2000. Similarly, the cross section at Malancha had<br />
once been as high as 2123 sq. meter (1952), which is recorded to be only 1467 sq. meter in 2000.<br />
On the other h<strong>and</strong>, the outflows from the drainage areas up to the outfall have increased over the<br />
years with the rapid urbanisation <strong>and</strong> associated paving of open l<strong>and</strong>s.<br />
The siltation of the Kultigong, unless remedied by dredging, may meet the same fate as that of the<br />
silted up Bidyadhari, which at one time had been conveying the storm discharge of Kolkata.<br />
Some of the cross sections of the drainage channels have been depicted in the following figures,<br />
along with their designed sections. It may be observed that most of the channels are heavily up <strong>and</strong><br />
require thorough cleanup. Some figures are also provided for the cross sections of the river Kultigong<br />
at specific locations.
