The quantity and quality of sediments supplied to such a large and complex system as the middle Paraná River, its differential transport through the drainage network, and the eventual sedimentation rates on the adjacent alluvial plain, are all variables that need to be known due to their crucial role on the type and survival of communities characterizing certain environments and on the possible interrelationships among them. Since the water transparency, the transfer of some nutrients and salts, the periodical renovation of alluvial plain surface soils, and the substratum features of lotic and lentic environments are all factors (processes) closely related to sediment, its pondering as a key variable for the state regulation of complex fluvial ecosystems has a sound justification.
