13. Paradigms for the maritime works project in the context of climate change. / Paradigmas para os projetos de obras marítimas no contexto das mudanças climáticas.
Global warming and the consequent increase of the mean sea level rise will be a challenge to the maintenance and development of offshore structures in the coming decades. Both global climate change and the fact that the extreme storms are experiencing substantial changes have profound consequences for the society and the environment. The study aimed to prese

14. Propriedades de retenção e condução de água em solos sob condições de campo e em forma de agregados, submetidos aos plantios convencional e direto
It has been unquestionable the importance of the studies and researches that seek for the understanding of the physical and hydraulic properties of the soil and that these studies and researches try to correlate them with the soil physical attributes. This work presents the use of the methodology presented in Leeds-Harrison et al. (1994), developed for the d

15. Waters in abundance - the reservoirs of Cantareira: a study of Industrial Archaeology / Água aos cântaros - os reservatórios da Cantareira: um estudo de Arqueologia Industrial
This research project used Industrial Archeology to analyze the material urban culture that existed in the city of São Paulo at the end of the 19th Century, which changed the configuration of the lives of those living in the city and changed the behavior of its citizens by implementing city sanitation systems and using new materials of construction that imp

16. Caracterização hidrogeológica do aquífero cauê, quadrilátero ferrífero, MG: Subsídios para a gestão dos recursos hídricos no quadrilátero ferrífero
The Cauê aquifer encompasses the geological unit that is the host of the Iron Quadrangle bodies of iron ore (Cauê formation). It has got significant hydrogeological potential, which is used for part of the water supply for Belo Horizontes metropolitan area, and has got a fundamental importance for the maintenance of the general environmental conditions of

17. Analysis of the optimal location of pressure reducing valves in water distribution systems considering multiple objectives / Estudo ótimo da localização de válvulas redutoras de pressão em sistemas de distribuição de água considerando objetivos múltiplos
In Brazil, water distribution systems with high leakage levels represent a problem with multiple implications for water utilities. Leakage, which accounts for the dominant component of water losses, produces negative effects from the economical, as well as from the operational perspectives: increase in pumping energy, compromise of water quality, increase in

18. Tectônica rúptil meso-cenozóica na região do Domo de Lages, SC / Meso-cenozoic brittle tectonics of the Lages Dome, SC
This study was focused on the meso-cenozoic tectonic evolution of the Domo de Lages region (south Santa Catarina State, Southern Brazil), through the analysis of brittle structures affecting sedimentary and igneous rocks, morphometric parameters, drainage network and main geomorphological features. Located in the border of the Paraná sedimentary basin, the

19. Significado morfotectônico dos planaltos isolados da Bocaina / Morphotectonics of the isolated plateaus of Bocaina
The Bocaina Plateau is situated on the eastern flank of the Continental Rift of Southeastern Brasil (CRSB), in the highest portions of the Serra do Mar, reaching more than 2000 meters in altitude. This and the Campos do Jordão Plateau comprise the high blocks of crystalline massifs of Southeastern Brasil. The Bocaina presents a succession of NW-SE topograph

20. Avaliação de sistemas de reparo para o problema de abrasão do concreto de superfícies úmidas em UHEs
The research field of construction pathology has been steadily growing lately due to natural degradation observed in different structures. In this sense, great attention has been devoted to special concrete structures such as hydroelectric power plants (HPP) because of their complexity and importance, socially as well as economically. One of the pathologies

22. Processamento e interpretação de dados 2D e 3D de GPR :aplicações no imageamento de feições kársticas e estruturas de dissolução no campo de petróleo de Fazenda Belém-CE
In Fazenda Belém oil field (Potiguar Basin, Ceará State, Brazil) occur frequently sinkholes and sudden terrain collapses associated to an unconsolidated sedimentary cap covering the Jandaíra karst. This research was carried out in order to understand the mechanisms of generation of these collapses. The main tool used was Ground Penetrating Radar (GPR). Th

23. MODELAGEM NUMÉRICA DE FLUXO 3D EM MEIOS POROSOS / NUMERICAL MODELING OF 3D FLOW IN POROUS MEDIA
Numerical simulations tend to simplify the behavior of real problems, mainly through the choice of 2D models to describe the hydromechanical responses of earth dams, excavations, foundations, etc., partly because it is easier to construct geometrical meshes, it is simpler to impose the required boundary conditions, the computer calculations are done more rap

24. ANÁLISE NUMÉRICA DO ALTEAMENTO DE BARRAGENS DE TERRA / NUMERICAL ANALYSIS OF RAISING EARTH DAMS
One of the activities related to dam constructions involves the raising of the existent structure, normally done with the objective of increasing the water storage capacity of the reservoirs, improving the safety factor of the embankment slopes or to ensure a better protection against possible water flooding. The raising of an earth dam can be predicted in t
