Bombetoka
Bay
From Wikipedia, the free encyclopedia
Bombetoka Bay is a bay on the northwestern coast of Madagascar
near the city of Mahajanga, where the Betsiboka River
flows into the Mozambique Channel. Numerous islands and sandbars
have formed in the estuary from the large amount of sediment
carried in by the Betsiboka River and have been shaped by the flow of the river
and the push and pull of tides
Along coastlines and on the islands,
the vegetation is predominantly mangrove
forests. In fact, Bombetoka Bay is home to some of Madagascar's largest
remaining communities of mangroves, which provide shelter for diverse mollusk
and crustacean
communities, as well as habitat for sea turtles,
birds,
and dugongs.
Along the northwest coast of Madagascar, mangroves and coral reefs
partner up to create dynamic, diverse coastal ecosystems.
The mangrove forests capture river-borne sediment that would smother coastal
reefs, while reefs buffer the mangroves from pounding surf.
Near water, shrimp
and rice
farming are common, while coffee plantations abound in the surrounding terrain.
Sedimentary transport and suspension
in Bombetoka Bay has significantly changed during the past 30 years, with a
dramatic increase in the amount of sediment moved by the Betsiboka river, and
deposited in the estuary and in offshore delta lobes. These changes have
adversely affected agriculture, fisheries, and transportation for one of
Madagascar’s largest ports [1]

There
are similar silted in and shallow areas throughout history. Dumfries (the town)
on Quantico Creek off of the Potomac River used to rival New York City as a
major port on the east coast of the USA, mostly because of the tobacco trade
with Europe (circa centuries ago). Then it silted in. Even Chah Bahar in Iran near the Pakistan
border (and on the Arabian Sea) was a very shallow area and bay three decades
ago. Now the Iranians say they will dredge it. Good luck, both now and in their
future.
