Water in the Lyari River Delta must empty into the sea through the Baba channel. (Tiny, oblong slivers in the channel are probably large ships.)

The result shows that, this area develops several sedimentation systems including alluvial fan, fan delta, subsea apron, delta, channel and lake and volcanic rock body.

The channel of meandering river, the distributary channel of delta front , distributary mouth bar , distal bar and the beach bar are the main sand body types.
