MONTOYA MORENO, Yimmy; VELEZ, Fabio  y  AGUIRRE RAMIREZ, Néstor. Morphometric features of a tropical flood plain lake (Hoyo swamp Los Bagres, Colombia). Rev.fac.ing.univ. Antioquia [online]. 2011, n.59, pp.203-214. ISSN 0120-6230.

In this paper the morphometric characteristics of Hoyo swamp's in Los Bagres (Colombia) and the theoretical predictions made from these characteristics are presented. The swamp was characterized as a shallow system with a large area about the size of the water column, the shape of a convex conical depression without turning points in V shape, with a broad line development coast generating a high influence on the watershed ecosystem. It has a high value of the fetch and the dynamic radius and a low relative depth, factors which together foster wide track action for the wind, so that trend is expected to dip to the thermal stability of the water column (polimixis). From the standpoint of trophic state may be considered as mesotrophic floodplain, as it presents low values of transparency and light attenuation coefficient. It was found that it presents morphometric differences regarding water system which is a part, so it follows that each body within the complex has its own characteristics, which are not defined in the study of the central body.
