Hi Agustin,
You can try with
Vector > Geoprocessing tools > Buffer(s)
Enable 'Dissolve buffer results'.
With your vector for sure it will take time ...

Hi!
how could I get a polygon to approach the river basin from a river
network? Is this something that could be
done with fTools? (note: the convex hull is not the solution, as the basin
is not convex)
