Ocorrência de movimentos de massa na bacia hidrográfica do Rio Paranhana - RS

Abstract

The Paranhana River’s hydrographic basin is constant scenario of naturals disasters. In times of rainfall events extremes, are common the occurrence of floods and mass movements. To contribute to the understanding of this scenario, were made field research in the region, where points were collected with a precision GPS receiver, of ocurrently of mass movements. This collection aims to identify patterns of points in the occurrence of mass movements, using satellite images and techniques of geoprocessing. Later, we will analyze the occupation of the population in risk areas, the number of occurrences and wich mitigations actions being taken by municipal district and civil defense. As the final work, will produce a map with areas most propicious to the mass movements, and areas of hazard with population at risk.

A bacia do rio Paranhana é constante cenário de desastres naturais. Em períodos de eventos pluviométricos extremos são comuns as ocorrências de inundações e movimentos de massa. Visando contribuir para o entendimento desse cenário foram feitas expedições de campo na região, e coletados pontos com um GPS topográfico das ocorrências de movimentos de massa. Busca-se identificar padrões nas ocorrências de movimentos de massa, utilizando técnicas de geoprocessamento e imagens de satélite. Posteriormente, será analisada a ocupação da população nas áreas de risco, o número de ocorrências e quais ações mitigadoras estão sendo realizadas pelos municípios e pela Defesa Civil. Como produto final será elaborado um mapa de áreas suscetíveis a movimentos de massa, e de áreas de perigo com populações em risco.
