Conteúdo: 	The immense plain of Pantanal of Mato Grosso (140,000 km2), situated in the central part of the South America (16-22 S, 55-58 W), correspods to a still active continetal base level. This plain is covered by Quaternary sediments, avove all alluvial products of the effluents of Paraguay River, and is subjected to seasonal floods, due to hydrologic regime of the main river. The interpretation of LANDSAT -TM images has permited to identify five parts, on the basis of "water landscape" vegetation, hydrologic dynamics and river network. The Nhecolandia region is directly influenced by the presence of the Taquãri River to the west of Negro River to the south. It presents a complex system of corixos and vazantes. The "Vazante de Corixao" region is covered by the savannah plants as well as the Taquari region. The former has few lagoons and is affected by the rising of the water level of the corixos and of the groundwater. Eastern Nhecolandia is characterized by the presence of an anasthomized system of corixos and vazantes and by the presence of cordilheiras and lagoas. In Central Nhecolandia the system baia-vazante-cordilehria-lagoa is developed. The floods are related to groundwater elevation and in a minor part, to the corixos and vazantes that present a not well developed anasthomized character. A sub-region in the northern part shows a more narrow system of cordilheiras-lagoas, crossed by a wider corixos and vazantes system.
