Abstract
The Pantanal wetland is part of the Upper Paraguay River basin. The major driving force of the wetland system is the annual oscillation between dry and wet seasons. This study focussed on the Taquari basin, a tributary of the Paraguay River, where erosion takes place and parts of the river silt up, resulting in an unstable system leading to serious flooding, ecological deterioration and economic losses. These effects could be the result of the increased precipitation since the 1970s, or land-use changes. The physically-based groundwater and surface water model SIMGRO was used to gain insight into the hydrology of the basin. Scenarios were defined to represent the increased precipitation situation and the change in land use. The increase in precipitation has a large effect on the discharges and the flow in the Taquari River and the change in land use has a very small effect.
