Resumen:
Iriondo MH, Paggi JC, Parma MJ (eds) The Middle Paraná River: Limnology of a Subtropical Wetland. Springer, Berlin Heidelberg New York (2007)     CHAPTER 3   ORIGIN, EVOLUTION AND TYPES OF THE FLOODPLAIN WATER BODIES Aldo R. Paira* and Edmundo C. Drago*   The Middle Paraná River contains a heterogeneous mosaic of thousands of lotic and lentic water bodies with changing shapes and areas according to the variable dynamics of the fluvial processes and the short- and long-term evolution of the different portions of the river floodplain. The aim of this chapter is to extend the knowledge and at the same time, to summarize a basic-wide characterization of the origin, shape and morphological evolution of the floodplain lakes and its relationships with the river dynamics and the aquatic and terrestrial vegetation. Furthermore, this work provides a sound data base for a better understanding of the hydroecological relationships between lotic and lentic riverine water bodies during their evolutional processes. The following issues were analyzed: 3.1. Introduction. 3.2. The Middle Paraná floodplain. 3.2.1. Floodplain characteristics. 3.2.2. Main channel. 3.2.3. Floodplain network: secondary channels. 3.3. Origin and shape of lentic water bodies. 3.4. Lake morphometry. 3.4.1. Lake shapes analysis. 3.5. Lake evolution. 3.6. Aquatic and riparian vegetation as morphological factor. 3.7. Concluding remarks.     * Instituto Nacional del Limnología (INALI) (CONICET-UNL). Santo Tomé,       Santa Fe. Argentina.
