Resumo(s)
Modelling the hydrology of hydrographic basins has shown itself as a useful tool
in environment management. The hydrological models can be used for multiple
purposes: estimate runoff from sequences of rainfall, access stream water quality,
quantify the diffuse pollution that reaches water masses such as estuaries, rivers
and lakes, etc. This study has as final objective to simulate and analyse the flow,
sediment transport and water quality as a function of landuse and soil type in the
basins of Maranhão and Pracana. The modelling system used is SWAT, Soil
Water Assessment Tool. In this first phase of the study the hydrodynamic
calibration of the model was performed using measurements of average daily
flows in five stations. The model compares well with the measurements; the
annual average flows are similar and the majority of the measured flow peaks
coincide with the model peaks.
