13. Estudo da dinâmica da solução do solo para o manejo da fertirrigação por gotejamento na cultura do pimentão / Study of dynamics of soil solution for the drip fertigation management in culture of pepper
Among various systems, the drip irrigation has been increasingly used, mainly because of its greater efficiency in water use. This work aimed to study the dynamics of soil solution, characterizing the distribution and storage of nutrients in the soil solution, and their absorption by pepper through the management of drip fertigation with two flows rates. The

14. âModelagem da IntrusÃo Salina Utilizando Analise de Sensitividade Adjunta â Estudo de Caso: Cap-Bon/Tunisiaâ / "Modeling of Saline Intrusion Using Sensitivity Analysis Assistant - Case Study: Cap-Bon/Tunisia"
Today the water is a natural well which limits the socioeconomic development and even the subsistence of the population. An attempt to minimize the problem of water scarcity has used the farming of groundwater. However, this growth of the use of groundwater was done inappropriately and with inadequate wells construction. This practice was eventually put at r

15. ANÃLISE TÃCNICO-ECONÃMICA DA RECUPERAÃÃO DE UM SOLO SÃDICO NO PERÃMETRO IRRIGADO CURU-PENTECOSTE-CE / Techno-economical analysis of the reclamation of a sodic soil in the Irrigated Perimeter Curu-Pentecoste-CE.
In the semi-arid part of Northeastern Brazil, the highest incidences of salinized areas are observed in land subjected to intense irrigated cultivation, in the âPerÃmetros Irrigadosâ (irrigated perimeters), particularly those where is used the surface method. The experiment was performed in the âNÃcleo Dâ (D Core) of the âPerÃmetro Irrigado Curu-Pent

16. Mapeamento do Aquífero Bauru situado sob a zona urbana de Araguari, MG / Mapping of Bauru Aquifer located in the urban area of Araguari/ MG
This paperwork approaches the main aspects related to the study of the Bauru Aquifer, its exploitation and use, as well as its potentialities in the region of Triangulo Mineiro, in special the city of Araguari, where the main focus of this research took place. The aim is to map the hydrological parameters of the Bauru formation, in the urban limits of Aragua

17. Modelagem numérica do fluxo da água no solo e do escoamento de base em uma bacia experimental em área agrícola no cerrado / Numerical modeling of the groundwater flow and the baseflow in an experimental watershed in an agricultural area of the cerrado biome, Brazil
This work presents an experimental study to evaluate the applicability of a groundwater numerical modeling tool, the FEFLOW, in simulating the water-table level variation and the baseflow in a watershed that is representative of agricultural areas of the Cerrado biome. For developing this study, some representative areas of this environment were selected, in

18. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

19. Algoritmos evolucionÃrios multipopulaÃÃo na otimizaÃÃo multiobjetiva da remediaÃÃo de Ãguas subterrÃneas / Multi-population Evolutionary Algorithm Multi-Objective Optimization of Groundwater Remediation
Through the last three decades the evolutionary algorithms have been successful on application to many areas. Easily applied, efficiency and confidence are the main advantages of the evolutionary algorithms. In the groundwater remediation, generally, the objectives are the cost minimization, minimization of contaminant presence, maximization of pumping effic

20. GRANTS FOR GROUNDWATER MANAGEMENT AT SANTA MARIA RIVER BASIN/RS / SUBSÍDIO PARA GESTÃO DAS ÁGUAS SUBTERRÂNEAS NA BACIA HIDROGRÁFICA DO RIO SANTA MARIA/RS
This study aims to provide subsidies for groundwater management at the basin of Rio Santa Maria-BHRSM. Located in the southwest of Rio Grande do Sul state, Brazil, on the edge of Paraná Basin and transitioning towards the Uruguaio Sul-Riograndense Shield, has an area of 15,797,300 square kilometers. About 16 formations occur in outcrops Pavão (2004), of wh

21. NUMERICAL MODELLING OF INFILTRATION OF HYDROCARBONS IN UNSATURATED SOILS USING THE FINITE VOLUME METHOD / MODELAGEM NUMÉRICA DA INFILTRAÇÃO DE HIDROCARBONETOS EM SOLOS NÃO SATURADOS UTILIZANDO O MÉTODO DE VOLUMES FINITOS
A large proportion of the population depends on groundwater for consumption. Thus, leakage of gasoline tanks represents a significant risk to public health besides the risk of fire and explosion in the sewer lines, due to the flammable gases. These tanks are generally located in the unsaturad soil above the groundwater level. It is therefore important to eva

22. Uso do gpr na caracterização da pluma de contaminação gerada por hidrocarbonetos a partir de um posto de combustível na praia de Búzios/RN
This work is the application of geophysical methods, using the Ground Penetrating Radar (GPR), with the objective of survey in a subsurface plume of contamination caused by a disabled gas station. The gas station is located on the Búzios beach in southern coast of the state to Rio Grande do Norte in an Area of Environmental Protection called Bonfim-Guaraír

23. Aspectos hÃdricos do aqÃÃfero Serra Geral na cidade de Cascavel
The Serra Geral Aquifer is composed by impermeable rocks, originated from basalt of Serra Geral composition, so the production of groundwater occurs only along faults and fractures of rocks and intersperse with more permeable rocks. Aiming at analyzing quantitative and qualitative hydric aspects, data from 77 and 36 wells were used respectively in Cascavel r

24. Geotechnical site characterization and study of an erosion process caused by urban setting / Investigação geotécnica e estudo de um processo erosivo causado por ocupação urbana
This dissertation presents geotechnical site characterization results of an erosion process area, in Bauru city, inland of São Paulo State, Brazil. The objective is to characterize the local soil and define the major causing factors for the erosion process evolution, which initiated with deforestation, soil sealing and discharge of pluvial and sewer water.
