摘要
O presente trabalho tem como objetivo descrever as caracter赤sticasmorfom谷tricas de sete lagoas do Pantanal Norte e discutir suas implica es na limnologia deste ambientes. Os parametros utilizados foram: 芍rea, volume, profundidades m芍xima, m谷dia e relativa, per赤metro, 赤ndices de desenvolvimento de volume e per赤metro,comprimento e largura m芍xima. De modo geral, as maiorias das lagoas s o rasas com pequenas profundidades relativas, assim menos propensas a estratifica es t谷rmicas e mais suscept赤veis a a o dos ventos que atua como agente na resuspens o de mat谷ria e mistura da coluna de 芍gua. Apresentam margens pouco irregulares e forma da bacia c ncava que s o menos influenciadas pelos processos de a eros o e sedimenta o. Varia es temporais na morfometria das lagoas conseq邦entemente afetam os padr es hidrodinamicos e limnol車gicos destes sistemas. The objective of this work is to describe the morphologicalcharacteristics 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, withlow 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 toerosion processes. Temporal variations in the morphometry of these lakes are related to the hydrodynamic and limnological patterns of these systems.
