4. Discussion
All events covered in this survey were recorded by the City Hall, which enacted
"emergency situation" for them, except the flood of 1983, where he was declared "State of
Public Calamity."
Floods have constituted one of the main problems for urban managers, since the
solutions are costly and difficult because permeate relationships of groups with different
interests and occupations for the most ancient and well established, as in the case studied.
Strategize in order to alleviate the population's vulnerability to these events is the great
challenge that society must be willing, starting from the understanding of the operation of the
physical system and how the changes made do interfere in their operation, creating risks not
only to environment, but mainly to society.
In the areas of the hidrographical basin where the occupation is not yet consolidated,
there is the possibility of seeking a rational use, as allocation of green areas for recreation,
which could be used for infiltration, decreasing runoff and flood risk to downstream; non
occupation of the areas around the watercourses, avoiding landfills and embankments, among
others.
These are simple measures, but can effectively reduce the risk to flooding and a more
harmonious relationship between man and environment.
