CONTRERAS, Félix Ignacio  and  PAIRA, Aldo Raúl. Morphometric Comparison of Lakes on the Alluvial Plain of the Paraná Medio River and the Lomada Norte (Corrientes, Argentina). Cuad. Geogr. Rev.

Shoreline development (D_L) is a morphometric measure that provides quantitative knowledge of the shape of a basin. The objective of this project was to compare the D_L of a group of shallow lakes, which despite being located in the same region, present geological and geomorphological differences. To that effect, we measured 925 shallow lakes corresponding to the totality of lenticular (lentiform) bodies of the Lomada Norte and 1500 fluvial lakes of the alluvial plain of the Parana Medio river. The results showed that circular lakes evolving into more complex forms predominate in the former, while in the latter, the majority are elongated lakes evolving into oval or circular shapes.

Keywords : Corrientes (Argentina); shoreline development; shallow lakes; morphometrics; Parana river.
