The mass wasting on hillslopes is a natural phenomenon, but it can be affected by human activities. In Brazil, one of the areas affected by these problems is the city of Florianópolis - SC. To solve or reduce these problems, local susceptibility studies are an essential issue. The objective of this research work is to analyse the landslide susceptibility in Saco Grande area, a borough of Florianópolis. For that, we tried to associate several physical and social aspects envolved in the deflagration of that phenomenon. A great number of preliminary thematic maps were made, by using aerial photographies, satellite images and field data. With the support of a geographical information system, some of these maps were overlaid, resulting in the elaboration of the Landslide Susceptibility Map.With all those information avaiable, we were able to make a susceptibility analysis of the study area. We find out that the occurance of landslides are strongly related to inappropriate occupation, which is responsable for a great number of rock falls, the most common type of mass wasting in Saco Grande area. We also realized that the middle portions of hillslopes are the most dangerous places and its occupation has to be avoided. Finally, we recomend the implementation of an emergency plan in the Florianópolis city council.

Recent data suggest that both Portugal and Brazil have seen an increase in the number of forest fires in protected areas. In Portugal, between 1992 and 2003 the annual average area burned in protected areas was 10,418 ha and in the period 2001-2005 was 16,025 ha. Nevertheless, in Brazil, the state of Santa Catarina stands out as the state recording a decrease in the number of fires. Based on these facts, the main objectives of the present research are to analyse the incidence, severity and causes of forest fires in protected areas in both countries and to assess the impacts of prevention and combat policies as well as the strategies and models implemented in the recovery of burned areas.

Phonemic theories must be classified according to their acceptance, or refusal, of the Saussurean distinction between form and substance. If one is to accept this distinction, one has to disagree with the principle that a phoneme is a phoneme in every environment, a disagreement which means rejecting the taxonomic and/or generative concepts of (partial and total) phonemic overlapping, suprasegmental versus inherent distinctive features, universality of distinctive features, phonemic (non morphemic) junctures, morphophonemes, and a phonographic system without any logographic element. As to the mute e in French, an attempt is being made to establish a theory of clusters independently from it, on the grounds of feature-compatibility: the mute e is thus considered as the (facultative) phonetic aspect of an incompatibility between phonemic features.

O processo de expansão urbana que se intensificou no Brasil em meados da década de 70 acarretou a ocupação de áreas de risco, tais como as zonas de encostas declivosas e de p la ní ci es de i nund açã o. RESUMO:O presente trabalho tem como objetivo principal analisar as áreas suscetíveis a inundações da bacia do rio Forquilhas, localizada no município de São José, Santa Catarina. Entrevistas concedidas pelos moradores da área de estudo a respeito das marcas de água foram utilizadas para determinar a altura das inundações, sendo posteriormente inseridas no mapa planialtimétrico, com curvas de nível a cada metro, sendo que o mapa final foi dividido em 5 classes de suscetibilidade (muito baixa, baixa, média, alta e muito alta). Assim, os resultados das análises mostram que a área inundável da bacia do rio Forquilhas é de aproximadamente 6 km², abrangendo 1.576 domicílios e 5.515 residentes, espacialmente distribuídos pelas diferentes classes de suscetibilidade, representando 17,67% do total da área de estudo e 20,25% da população total. PALAVRAS-CHAVE:Desastres Naturais; Áreas Suscetíveis a Inundações; bacia do rio Forquilhas; Expansão Urbana; Impactos Ambientais. ABSTRACT:The main objective of this work is to analyze the susceptible areas of floods of the Forquilhas river basin, located in São José, Santa Catarina State. Interviews given by the residents of the study area about the water traces were used to determine the height of the floods, and were subsequently inserted in the planialtimetric map, with curves at 1 meter each, where the final map was divided into 5 classes of susceptibility (very low, low, medium, high and very high). Therefore, the analysis results show that the floodplain of the Forquilhas river basin is approximately 6 km², covering 1.576 houses and 5.515 residents, spatially distributed in the different classes of susceptibility, representing 17,67% of the total study area and 20,25% of the total population.
