Answer Details

(a) Advantages and limitations of water transportation

Advantages:

It is the cheapest means of moving bulky and heavy goods over long distances.
It requires no expensive track construction - the natural waterway or sea is the route.
It can carry very large loads (bulk cargo such as oil, grain and ores) in a single voyage.

Limitations:

It is very slow compared with road, rail or air.
Waterways are interrupted by rapids, waterfalls, shallow water, sand bars and freezing/silting, limiting where ships can go.
It can only serve places near the coast or navigable rivers, and cannot reach inland areas directly.

(b) How the limitations can be overcome

Slowness: use faster, modern powered vessels and combine water transport with road, rail or air for through movement.
Rapids, waterfalls and shallows: construct canals, locks, dams and by-pass channels, and carry out dredging to deepen and widen channels; build breakwaters and clear sand bars.
Limited reach inland: develop ports with good road and rail links (container/intermodal transport) so goods can be moved onward to inland destinations; build inland waterways where possible.
