Morphometric characterization and its limnological implications in Northern Pantanal lakes - DOI: 10.4025/actascibiolsci.v30i3.3628

Abstract

The objective of this work is to describe the morphological characteristics of seven Northern Pantanal lakes and discuss their implications on the limnology of these environments. The following morphological parameters were used: area; volume; maximum, mean and relative depths; perimeter; volume and perimeter development indices; maximum length and width. Generally, most lakes are shallow, with low relative depths, suggesting little thermal stratification, as they are more susceptible to mixing of the water column and suspended sediments by wind action. Most lakes have regular banks (few irregularities) and have a concave shape, and thus are less subject to erosion processes. Temporal variations in the morphometry of these lakes are related to the hydrodynamic and limnological patterns of these systems.
