Creation of risk areas: the problems with flooding in the Rio Vermelho district, Florianópolis / SC

Abstract

This paper discusses the creation of flood risk areas in the Rio Vermelho District / SC. This district has different types of wetlands, but those places located on the sandy marine terrace were the subject of intense human occupation because they are not always wet over time. Former residents knew that these areas flooded in episodes of exceptional rainfall, however, are migrant people who bought land there. The irregular soil parceling, without planning and inspection of the public power associated to the ignorance of the natural dynamics of the place, created areas of risk to flood. Structural measures of drainage will be unable to stop the flooding completely, so should also be implemented non-structural measures to reduce the vulnerability of the residents.
