Abstract

When the Parana River’s water level of the river head area rose in the winter of 2013, a study was made with the sampling of the sedimentation to find out the rate, the quantities and proportions of lime, clay and sand in the sediment carried by the water. The traps used, that were located prior to the arrival of the water to the island, measured 30*30 cm; they were then analysed at the end of a period of 65 days. The maximum value deposited was 1180 g*m2 in the entire study period with a daily deposition rate of 18,2 g*day-1*m2. Lime was the most abundant portion of the sediment deposited.
