The evolution basin
of the port of Porto Alegre is comprised by
two deeper areas, connected by the channel
of Navegantes, about 700m. long, parallel
to the wharf.
The first bordering area from A-7 to B-3 warehouses
of Mauá wharf is around 1.461m long
and a width ranging from 500m to 400m. Its
depth referred to the hydrographic zero ranges
from 5.50m to 11.00m. These depths are natural,
and do not require any maintenance as dragging.
A regular cleaning at the exit area of the
pluvial manholes is enough.
The opening of Navegantes channel resulted
from the need of connecting Mauá and
Navegantes wharves. Its beginning is in front
of B-2 warehouse and it extends up to the
beginning of the alignment perpendicular to
Navegantes wharf, at C-6 warehouse. The extreme
embankment is 250m away from the wharf parameter.
Its average width is 80m, and the normal depth
is 7.0m. The channel cuts a region among basins
with depths that oscillate around 9.50m.
The second area begins at C-6 Warehouse and
extends to Getulio Vargas passage (where Marcilio
Dias sanitation wharf starts), and is about
2.900m long with a width ranging from 300m
to 200m, and minimum depth of 6.50m. In this
area there are basin gullies originated from
drags, with depths of up to 15.00m, resultant
from the removal of material to be used at
Navegantes wharf embankment.
The basin bordering Marcílio Dias wharf
is around 1,100m, with a width ranging from
200m to 130m. It has irregular, decreasing
depths, reaching 2.00m, and there one can
find a lane for nautical sports. |
