Deltaic
system
The delta of the Orinoco is almost only in
the world for three reasons: the bed of
the Orinoco doesn't go centered, it lacks
lagoons and it is an oceanic delta. It is
divided in two
deltas: the general, located from the left
riverbank of the pipe Araguao, in
northwest address, until the pipe Mánamo with north
direction until the respective outlets in
Boca
Araguao and Flints. And the secondary one,
located among the right riverbank of the
pipe Araguao and the left of the Big River,
main bed of the Orinoco in the delta. The
dominant
landscapes are muddy plains, so much
marine as fluvial, with slopes that
scarcely arrive to 2%, except in the southeast of the region,
where the relief is waved or broken and
the
slopes can arrive to 25%.
