Morphogenesis and connectivity across fluvial environments of high Parana River, South-Center of Brazil

Abstract

This work presents a study about the interactions between geomorphologic patterns and the connectivity of aquatic environments and other forms of the high Parana River floodplain system. The superposition of relict fluvial systems produces a diversity of alluvial forms in the fluvial plain. These relict forms present in the fluvial plain are fairly stables with the current hydrodynamic, with smaller connectivity with the Parana River channels. Its suggest autogênic processes´ dominance. However in the main channels, the forms with genesis in the current river, are less stable, and this suggests that allogenic process insure greater geomorphic dynamism to the hydrarc evolution, due to the largest connectivity degree with the main channels.
