| ABSTRACT The Cerrado is a vegetation complex with a wide variety of phytophysiognomies, and sustainable management is essential for maintaining biodiversity. Morphopedology is a tool that can assist in developing plans for control of soil and land use, especially in evaluating the potential of soil erosion processes. This technique allows landscape units considered “homogeneous” to be distinguished, as a result of interaction between physiographic conditions. The aim of this study was to evaluate potential for erosion in São Miguel do Araguaia, state of Goiás, Brazil, through definition of morphopedological compartments (MPC), on the assumption that soil use has increased erosion. Landscape units were identified through use of geology overlay, hypsometry,... |

| Studies on hydrology, agro-meteorology, soil loss and climate change scenarios depend on weather information, which may not be available. Weather generators, such as the CLIGEN, can synthesize daily climate series statistically similar to the observed data. The objective of this study was to evaluate the CLIGEN in generating series in the climatic conditions of Paraná, Brazil, which show transition between Cfa and Cfb climates. Observed data from 20 weather stations from 1975 to 2009 were compared with synthetic series generated with the same number of years. Mean and standard deviation of the number of wet days, daily precipitation, normalized storm peak intensity, solar radiation, maximum and minimum temperatures and dew point were analysed. The... |
