ENCHENTES NO RIO GRANDE DO SUL DO SÉCULO XXI (the floods in Rio Grande do Sul during 21th century)
Abstract
No Rio Grande do Sul, as enchentes constituem-se em fenômenos naturais já conhecidos pela população, em especial, aquelas que habitam os vales dos principais rios sul-rio-grandenses. O objetivo geral desta pesquisa consistiu em identificar as correntes perturbadas e os tipos de tempo responsáveis pela gênese das enchentes nas três Regiões Hidrográficas do Estado entre os anos de 2000 e 2011. Aplicou-se metodologia baseando-se no Ritmo Climático. Nesse sentido, observou-se que a maior parte das enchentes ocorreu em função de ciclos climáticos nos quais havia a participação da Frente Estacionária e Ciclogêneses, com e tipos de tempo inerentes aos domínios destes sistemas.
Palavras-chave: Enchentes; Regiões Hidrográficas; Correntes Perturbadas; Tipos de tempo.
ABSTRACT
In Rio Grande do Sul, the floods are natural phenomena in the known population, in particular those that inhabit the valleys of major rivers in the State. The objective of this research concerned to identify the disturbed currents and weather types responsible for the genesis of floods in three Hidrographic Basins regions in the State, between the years 2000 and 2011. Methodology was applied based on the rhythm of Climate. Accordingly, it was observed that most of the flooding occurred due to climatic cycles in which there was the participation of the stationary front and cyclogenesis with time and types of fields inherent to such systems.
Key words: Floods; Hidrographic Basins regions; Disturbed currents; Weather types.
RESUMEN
En Rio Grande do Sul, las inundaciones son fenómenos naturales conocidos por la población, especialmente a los que habitan en los valles de los principales ríos del estado. El objetivo general de esta investigación fue identificar las corrientes alteradas y tipos climáticos responsables de la génesis de las inundaciones en las tres demarcaciones hidrográficas del estado entre 2000 y 2011. Metodología aplicada se basa en el ritmo de clima. En este sentido, se observó que la mayor parte de las inundaciones se produjeron debido a los ciclos climáticos en los que no había participación fija delantera y la ciclogénesis con el tiempo y tipos de áreas inherentes a estos sistemas.
Palabras-claves: Inundaciones; Regiones hidrográficas; Sistemas de producción de lluvia; Tipos de tiempo.
