14. Hydrodynamic modeling and morphological analysis of Lake Água Preta: one of the water sources of Belém-PA-Brazil
The main contribution from this paper includes the hydrodynamic modeling and morphological analysis of Lake Água Preta in Belém city, Pará State, Brazil. The lake bathymetry was taken through the data provided by COSANPA (the local sanitation and water supply company) dating back to 1975, and from a 2009 field study. Both bathymetries produced two terrain

15. Modelagem computacional e calibraÃÃo da condutividade hidrÃulica horizontal em aqÃÃfero da Bacia Sedimentar do Araripe utilizando o mÃtodo iterativo do gradiente hidrÃulico / Computational modeling and calibration of water-bearing the horizontal hydraulical condutividade in of the Basin Sedimentary of the Araripe using the iterative method of the hydraulical gradient
O processo de calibraÃÃo de parÃmetros hidrodinÃmicos representa parte importante dos modelos e sua abordagem geral consiste em minimizar uma funÃÃo objetivo expressa pela diferenÃa entre as cargas hidrÃulicas observadas e calculadas. Guo e Zhang, na dÃcada de 90 e, depois, Schuster e AraÃjo (2004) propuseram um processo alternativo para estimaÃÃ

17. Simulação hidrológica de rios com grandes planícies de inundação
Besides understanding the current hydrologic behavior of a river and floodplain drainage system, it is important to be able to predict its future conditions in light of possible impacts due to anthropogenic activities and climate variability. Mathematical modeling is the ideal tool for this purpose. For large scale hydrologic systems, if the objective is to

19. Modeling and experimental study of hydrodynamic and drying characteristics of an industrial rotary dryer
The purpose of this work was to analyze the hydrodynamic and drying aspects of a rotary dryer used in a fertilizer industry. A set of equations to predict the solids holdup in the flights, the length of fall, the residence time of particles and the drying variables was evaluated by comparison to experimental measurements performed in an industrial rotary dry

20. NUMERICAL MODELING OF SEWAGE PLUME DISPERSION FOR THE SANTOS OUTFALL / Modelagem numérica da dispersão da pluma do emissário submarino de Santos
Sewage plume dispersion for the Santos outfall was studied using numerical models, coupling hydrodynamic, near field and far field models. Experiments were conducted for the 1979 original outfall design, for the new 2009 outfall configuration and also for a third arrangement suggested here, which duplicates the emissary length comparatively to the original 1

22. Fuzzy logic applied to the modeling of the transfer of water in soils / LÃgica fuzzy aplicada à modelagem da transferÃncia de Ãgua em solos
Modeling water movement in the unsaturated soil requires a great number of parameters and variables such as the initial soil-water content, the saturated soil-water content, and the saturated hydraulic conductivity, which can relatively easily be assessed. Other functions such as hydraulic conductivity and matric potential which are nonlinear functions of th

23. Modelo matemático para avaliação hidrodinâmica em reatores tubulares operando em regime não-permanente / Mathematical model for hydrodynamic evaluation of pipe reactors with diffusion operated in non-steady flow
Mathematical models for hydrodynamic characteristics evaluation of reactors are commonly used however there is a lack of information in the literature concerning the application of mathematical modeling for non-steady state flow. In this thesis, it is presented a non-steady mathematical model to simulate the hydrodynamic behavior of pipe flow reactors with d

24. Análise crítica da utilização de modelagem matemática na avaliação da dispersão de efluentes leves no litoral da Baixada Santista ( Estado de São Paulo). / The analysis of mathematical models in the assessment of effuents dispersion in Baixada Santista coastline (State of São Paulo).
The prediction of the hydrodynamic water circulation and pollutants dispersion, mainly in coastal areas, has been a problem that engineers have been facing. This is due to the increase environmental impacts that involve coastal engineering work and management. The usage of mathematic modeling as assessment tool is necessary for these studies. The main purpos
