As the proposed link canal would cross a number of rivers and rivulets, a num-
ber of cross-drainage structures would be needed. One such structure would be a
level-crossing for the Teesta. Bangladesh expressed doubts on the feasibility of
such a structure, as the river carries huge volume of sediment. These structures
including canal embankments normally cause serious drainage congestion on either
side, depending on the natural ground slopes, as experienced while excavating the
Farakka feeder canal. Their routine repair and maintenance of such a long canal and
the drainage of its outlets would be very difficult tasks.
