Wetland management within the alluvial fan for the Taquari River in the Pantanal of Brazil requires understanding the channel-feomorphology. The alluvial fan of Taquari has an area of about 50,000km2, Analyses of hydrologic, geomorphic, grain size distribution, and remote sensing data allowed the development 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 anastromosing 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 coarse material (>0,063 mm) in the river, river margins, and fllodplain. The anastromosing section begins at the intersection point of the fan approximately 100 km down the fan head. The unconfined character of the floodplain in the distral region of the fan is due to lower bank heights and progressive descrease of floodplain elevation in relation to river water level. Decreasing downstrean discharge is due to overbank flow. The decrease in suspended sediment concentration downstrean reveals that almost all the sediment load is deposited along the distal region of the alluvial fan. Decreasing grain size within sediments of the river, margins, and floodplain indicates that fine material is deposited in the fllodplain, while coarse material remains within the channels. Spectral mixture analysis of Landsat TM imagery, usiing sediment-laden water, clear water and vegetation revealed changes in the hydrological behavior of the Taquari River as enlarging floodplain area in the distral fan.
