| Palavras-Chave | Land-use change streamflow SWAT model scenarios Amazon region Xingu watershed | |||
| Resumo | Accelerated land use change in the Amazon biome over the last decades has raised questions about the extent and consequences of the impacts on the local hydrology. Land cover patterns control surface runoff, infiltration, evapotranspiration and sediment production within the watershed, directly influencing the streamflow dynamics and sediment yield. High deforestation rate at agricultural frontier areas as well as the recent reduction of this rate can significantly affect hydrological processes. The resulting changes on the regional hydrological cycle affect ecosystem function as well as navigation, agricultural activities, power generation and riverside inhabitants, either directly or indirectly. Beyond the scarce availability of hydrologic and sediment data, the Amazon region also lacks studies that establish a relationship between land use and the hydrological system. Applying hydrological models, such as Soil and Water Assessment Tool (SWAT), in the Amazon region is crucial to the analysis of the system's response to future land use and climate change scenarios. The Xingu Watershed (509.000km²), located at the agricultural frontier area of Eastern Amazon is divided into areas of extensive native forests, and areas with differing levels and types of agricultural activities. This watershed has suffered intense deforestation over the last four decades, with expansion of grain cropland and cattle ranching at the southern region of the basin. As of 2004, government policies increased the discipline of environmental legislation which has since partially reduced the advance of deforestation. In this context, this work aims to model the relation between land use and water discharge of the Xingu Watershed using the SWAT model, analysing the impacts of future land use scenarios. To overcome the issue of climate data scarcity, 1998-2016 Tropical Rainfall Measuring Mission (TRMM) data series were used along with data provided by the Brazilian National Meteorological Institute (INMET). Daily streamflow data were obtained from the Brazilian National Water Agency (ANA). Data from the TerraClass project (National Institute for Space Research - INPE/Brazil) were used as land use input, whereas soil physical characteristics data were prepared using pedotransfer functions based on studies and Amazonian soil texture data from Radar da Amazonia Project (RADAMBRASIL) and the Brazilian Soil Survey for Amazonia (EMBRAPA). Simulations are currently being performed on two Xingu River sub-basins: Fresco River sub-basin (43.000km²) and Iriri River sub-basin (142.000km²). Initial results from these simulations suggest a good model fit when simulated flow is compared to the observed flow from fluviometric stations (r2 = 0.87, NS = 0.85). The continuation of this work aims to expand modelling to the entire Xingu Watershed, enabling the simulation of future land use scenarios. | |||
