Abstract Based on the growing food and energy demand and the high environmental changes resulting from the conversion of natural environments into agriculture land, researches are essential to understand how anthropogenic changes, through land-use change and land cover, affect the hydrological processes. Understanding the infiltration and runoff processes is an important step for the development of strategies to guarantee the sustainability of ecosystems, restoration, and preservation of natural vegetation. Thus, this project has as main objective the preliminary study about how the anthropic pressure, through the agricultural crops, interferes on infiltration and runoff. The present study will be developed in experimental plots under different land uses found in Southeastern Brazil: sugar cane, Cerrado stricto sensu, soybean, and bare soil. For this, the study area, already in operation, will be continuously monitored over two years by collecting meteorological data (precipitation, air temperature, solar radiation, wind speed, and atmospheric pressure) and hydrological (surface runoff and soil moisture). The information collected will serve as input data, calibration and validation of the Hydrus model. Once calibrated and valid according to local particularities, the model will become a useful tool for describing hydrological behavior under current soil uses and occupations in Cerrado biome areas. This will better understand the hydrological responses to current events and the analysis of future scenarios under changing climate conditions. (AU) | |
