Abstract

This paper aims to carry out a mapping of natural disasters, gradual floods, occurring in Rio Grande do Sul (RS) state from period 2003 a 2009. Records of the events were obtained by State Civil Defense Authority to analyze the preferential period for these occurrences and the most affected areas. The results show that regarding the gradual floods, the most affected areas of RS were Depressão central (35%), the lowlands of Planalto Médio (18%), Alto Uruguai (14%), Encosta inferior do Nordeste (10%) and Missões (9%) regions. The period between the spring (finish) and summer (begin) season was preferential for occurrences. Also was found that gradual floods did not occur only in years with presence of El Niño and La Niña climatic events. It’s also occurred in periods without the influence of these phenomena (neutral years).
