14. Agrarian soil and sediment redistribution and quality in slopes with riparian forests: a case study for Goiatuba, Brazil / Redistribuição e qualidade de solos e sedimentos agrícolas em vertentes com mata ciliar: estudo de caso em Goiatuba (GO), Brasil
Soil erosion is associated with environmental degradation because of inadequate use of natural resources in modern agriculture, thus promoting in and off-site impacts, represented by soil, water and nutrient losses, silting and contamination of riparian ecosystems. In the Brazilian Cerrado region these impacts become more evident by its fast conversion to ag

15. As conseqüências do assoreamento na operação de reservatórios formados por barragens / The consequences of silting in the operation of dam made reservoirs
O assoreamento de reservatórios formados pela construção de barragens interfere inevitavelmente no seu volume útil. O volume útil é o compartimento responsável pelo armazenamento da água para o atendimento dos usos consuntivos e não consuntivos do sistema e a sua redução altera o atendimento das demandas. Nesta pesquisa foi investigada a interfer�

16. Urban expansion and geomorfological expansion in backwater of reservatories: comparative analisis of two drainage basins that are in the source of Guarapiranga, São Paulo / Expansão urbana e evolução geomorfológica em remansos de reservatórios: análise comparativa de duas bacias hidrográficas em guarapiranga, São Paulo
The environmental problems created by the accelerated urban growth in the last fifty years have brought severe consequences to the group of people living in big urban centers. For this reason many scientists, mainly in the field of Earth sciences, have searched the development of new techniques, methodologies and parameters to measure, recognize and attenuat
