Relação Intensidade-Duração De Precipitações Capazes De Desencadear Escorregamentos Em Porto Alegre - Rs

Abstract: Resumo:A equação que relaciona a intensidade e duração da precipitação com a ocorrência de escorregamentos é uma ferramenta simples para antecipar e prevenir os desastres hidrológicos. O objetivo do presente trabalho foi elaborar uma curva de intensidade-duração para o município de Porto Alegre. Para isso, foram analisados dados pluviométricos e registros de escorregamentos ocorridos em Porto Alegre no período de 2006 a 2013. A análise foi feita por geoprocessamento no software ArcGIS seguida do uso de Excel. … Show more
