Wetland management within the alluvial fan the Taquari River in the Pantanal of Brazil requires understanding the channel-floodplain geomorphology. The alluvial fan of Taquari has an area of about 50,000 km2. Analyses of hydrologic, geomorphic, grain size distribution and remote sensing data allowed the developement of a conceptual model that accounts for the identification of two distinct sections of the alluvial fan of the Taquari River, a meandering section and an anastomosing section. The meandering section is located in the region of the fan head. Temporal variability of discharge in this reach is due to seasonality of precipitation. Channel and active floodplain are entrenched within walls of older terrace deposits. There is a predominance of coarce material (>0.063 mm) in the river, river margins and floodplain. The anastomosing section begins at the intersection point of the fan, approximately 100 km down the fan head. The unconfined character of the floodplain in the distal region of the fan is due to lower bank heights and progressive decrease of floodplain elevation in relation to river water level. Decreasing downstream discharge is due to overbanck flow. The decrease in suspended sediment concentration downstream reveals that almost all the the sediment load is deposited along the distal region of the alluvial fan. Decreasing grain size within sediments of the river, river margins and floodplain indicates that fine materials is deposited in the floodplain, while coarse material remains within the channels. Spectral mixture analysis of Landsat TM imagery, using sediment-laden water, clear water and vegetation revealed changes in the hydrological behavior of the Taquari Rivers as enlarging flooplain area in the distal fan.

O sistema de producao de gado de corte, desde a preparacao para a estacao de monta ate a terminacao dos animais, necessita de um planejamento sanitario. Esse controle, em uma primeira analise, visa a dar maior seguranca economica ao produtor, pela diminuicao dos riscos de perdas na produtividade do sistema. Ao mesmo tempo, o sistema vai oferecer um produto mais seguro, do ponto de vista sanitario, para o consumidor. Portanto, a viabilidade da resposta dos investimentos no sistema de producao, com relacao ao melhoramento genetico e nutricao animal, vai depender da eficacia da prevencao de doenca no sistema. Este trabalho tem o objetivo de discutir a importancia do planejamento sanitario nas doencas consideradas importantes, sem a pretensao de esgotar o assunto, para a diminuicao dos riscos sanitarios de consequencias economicas para o sistema de producao de gado de corte. |
