El concepto de "pulso de inundación" en relación a las planicies aluviales del sistema fluvial Paraná-Paraguay

Abstract

The present study deais with the floodplains occurring in the Paraná-Paraguay fluvial system, with special emphasis on their degree o f fitness to the “flood-pulse” concept proposed by Junk et al. (1989). “Fringe” floodplains o f different stretches of the Paraná river and o f the lower reach o f the Paraguay were found to keep many similarities. Instead. both the Upper Paraguay’s Pantanal and the Paraná’s Delta pose problems that require specific studies in order to interpret correctly, and eventuallyadjust, the “pulse” concept, as well as to better assess its effects on the river’s productivity.
