Image Caption:
Mouth of Rio Parnaiba
A large sand dune region to the west of the mouth of the Rio Par-
naiba (1) can be seen in the low oblique, east-looking view. Sed-
iment from streams, such as the Rio Parnaiba which is over 1290
km long, and rises in the Brazilian Highlands, is carried to the
sea and then eastwards along the coast by strong nearshore
currents. Wind blows this sand from the beach forming the large,
white sand dune areas in this region. Excessive deforestation in
the northeastern Brazil Highlands has increased soil erosion.
The dunes in this region should be increasing in size. (STS5-
40-1234)
