The municipalities in the Uruguay river margins has been frequently reached by flooding which leave a large number of uncovered people and, sometimes, fatal victims. In this sense, the present study has the central subject to carry on a study of number of flooding occurrences in the municipalities' emarginated by Uruguay River in the Rio Grande do Sul State between the years of 1980 and 2005. The specific subjects are consisted in to present the municipalities where those events occurred in a cartographic manner, and it is intended to relate each flooding event to the daily collected pluviometer data in 10 Meteorological Stations distributed in Uruguay hydrographic sub-basins as well. Data referring to flooding were researched Zero Hora and Diário Oficial do Estado do Rio Grande do Sul collection; pluviometer data was obtained in Fundação Estadual de Pesquisa Agropecuária (FEPAGRO) and Agência Nacional das Águas (ANA). The pluviometer data analyses were undertaken by means of parametric statistic technique. The 10 Meteorological Stations precipitation analysis along the affected in each flooding occurrence was carried on observing at first the event range and at last the rain quantity in the significant Meteorological Station, being presented as cartograms. In this way, the present work aims to contribute to the understanding of flooding events that can, directly or indirectly, to interfere in most of the human activities accomplished. The knowledge of the pluviometric regime in relation to occurrence of flooding allow the population to think out the spaces ant to use the hydric resources in a more efficient and rational manner.
