The general practice of TRM operation was to construct one
or two link canal to connect the tidal basin with the river. But
in that case most of the sedimentation took place in the
vicinity of the link canal [4]. Normally silt does not spread out
in the areas far away from the canal. Therefore, to get the
uniform sedimentation inside the tidal basin dredging or reexcavation
of
the canals
was viewed
essential.
