RE, Mariano; KAZIMIERSKI, Leandro D.  and  MENENDEZ, Ángel N.. Sedimentation in navigation channels under the context of climate change. Tecnol. cienc. agua [online]. 2014, vol.5, n.1, pp.05-21. ISSN 2007-2422.

A numerical modeling methodology for sedimentation in navigation channels is used to evaluate effects of Climate Change, through consideration of potential changes in the river discharge. This methodology, which is explained in detail, is illustrated through its application to a 'paso' of the Parana River (South America), validating its results with maintenance dredging data. It is shown that, keeping the present dredging elevations, the sedimentation volume would increase with the increment in discharge, and vice versa, with relative rates of change significantly larger than that of the discharge. If, on the contrary, the dredging elevations were adjusted to new reference levels, the trend would be the opposite, with relative rates of change only moderately larger than that of the discharge, in absolute value.

Keywords : sedimentation; navigation channels; dredging; Climate Change; Paraná River.
