Estimativa da produção de sedimentos utilizando a curva-chave de sedimentos [PDF]
Ciência e Natura, 2021 Quantification of sediment yield is important in determining the impacts of erosion processes on the watersheds. One way to determine their values is through the construction of the sediment-transport curve. The objective of this work is to calculate the sediment yield and to analyze the time variation in a hydrosedimentological monitoring station by ...
