O Padrão de ondas no lago Guaíba e sua influência nos processos de sedimentação
(2007) [Tese]O Lago Guaíba configura-se como o grande depositário das águas de uma bacia hidrográfica que engloba boa parte do centro e nordeste do estado, estendendo-se por uma área aproximada de 84.700 km2 que abrange mais de 250 ... -
Phosphorus forms in sediments as indicators of anthropic pressures in an agricultural catchment in southern Brazil
(2017) [Artigo de periódico]Phosphorus (P) fractionation is a suitable procedure to ascertain P lability in sediments and is able to distinguish sources of P under different soil management practices in a catchment. Brazil is the second largest ... -
Physico-chemical variability and heavy metal pollution of surface sediment in a non-channeled section of Dilúvio Stream (Southern Brazil) and the influence of channeled section in sediment pollution
(2019) [Artigo de periódico]Dilúvio Stream flows through an area with a great population density in Porto Alegre, Southern Brazil. The anthropogenic influence in the surroundings impacted negatively the quality of the sediments of Dilúvio Stream and ... -
Quantifying sediment source contributions in contrasted agricultural catchments (Uruguay River, Southern Brazil)
(2021) [Tese]Intensification of water erosion by agricultural activities is one of the main causes of soil degradation in subtropical regions. In addition to the on-site negative impacts observed in cropland, the excess of surface ... -
Sampling strategies to estimate suspended sediment concentration for turbidimeter calibration
(2017) [Artigo de periódico]The influx of sediments carried by rivers can be measured continuously using a turbidimeter through the indirect relationship between turbidity and suspended sediment concentration (SSC). However, this process is dependent ... -
Sediment source fingerprinting : benchmarking recent outputs, remaining challenges and emerging themes
(2020) [Artigo de periódico]Purpose:This review of sediment source fingerprinting assesses the current state-of-the-art, remaining challenges and emerging themes. It combines inputs from international scientists either with track records in the ... -
Tracing the origin of reservoir sediments using magnetic properties in Southeastern Brazil
(2020) [Artigo de periódico]Determining the origin of eroded soil is essential to design effective soil erosion control strategies which preserve the soil resource, enhance agricultural productivity, and reduce the negative impacts of soil erosion, ...
