Abstract:
Tsunamis need to be studied more carefully and quantitatively to fully understand their destructive impact on coastal areas. Numerical modeling provides an accurate and useful method to model tsunami inundations on a coastline. However, models must undergo a detailed verification and validation process to be used as an accurate hazard assessment tool. Using standards and procedures given by NOAA, a new code in hydrodynamic modeling called GPU-SPHysics can be verified and validated for use as a tsunami inundation model. GPU-SPHysics is a meshless, Lagrangian code that utilizes the computing power of the Graphics Processing Unit (GPU) to calculate high resolution hydrodynamic simulations using the equations given by Smooth Particle Hydrodynamics (SPH). GPU-SPHysics has proven to be an accurate tool in modeling complex tsunami inundations, such as the inundation on a conical island, when tested against extensive laboratory data.

Abstract:
Application of Lagrangian meshless methods in modeling granular flow has been a major concern for researchers due to their particular nature. For modeling granular movement, it is assumed that the particles are continuous. The SPHysics code is developed for modeling the movement of Newtonian fluids in which the pressure is derived from the state equation. In this study, [Formula: see text] and Herschel–Bulkley–Papanastasiou (HBP) viscoplastic models are implemented in the SPHysics code to analyze the movement of grains induced by the applied stresses. In the first model, the movement of granular particles is based on the characteristics such as inertia and friction coefficient, and in the second model, the movement is related to the non-Newtonian viscoplastic behavior of fluids. The accuracy of the models is evaluated by simulating the experimental benchmarks for granular dam break. The effect of length-to-height ratio on the failure mode of dam break phenomenon is also investigated. The performance of the models is increased by introducing the gate removal speed and also the harmonic mean of the viscosity instead of the viscosity proper to each particle. This study shows that the models could capture the behavior of grains in the static and the dynamic parts of the mass body.

Abstract:
This study was conducted to compare water surface profiles with standard ogeecrested spillways. Different methods were used, such as (experimental models, numerical models, and design nomographs for the United States Army Corps of Engineers, USACE). In accordance with the USACE specifications, three different models were constructed from rigid foam and then installed in a testing flume. The water surface profile has been recorded for these models with different design heads. For modeling the experimental model configurations, a numerical model based on the smoothed particle hydrodynamics (SPH) technique was used and is developed to simulate the water surface profile of the flow over the ogee-crested spillway. A 2D SPHysics open-source software has been used in this study, using the SPH formulation to model fluid flow, developing the SPH boundary procedure to handle open-boundary simulations, and modifying the open-source SPHysics code for this purpose. The maximum absolute difference between the measured and computed results of the water surface profile for all head ratios of (H/Hd), does not exceed 4.63% at the crest region, the numerical results for the water surface profile showed good agreement with the physical model results. The results obtained experimentally and numerically by SPH are compared with the CFD results in order to be more reassuring from the results. Additional comparisons were made using interpolated data from USACE, Waterways Experiment Station (WES), and design nomographs. The SPH technique is considered very promising and effective for free surface flow applications.

Abstract:
Currently, the accurate prediction of the impact of an extreme wave on infrastructure located near shore is difficult to assess. There is a lack of established methods to accurately quantify these impacts. Extreme waves, such as tsunamis generate, through breaking, extremely powerful hydraulic bores that impact and significantly damage coastal structures and buildings located close to the shoreline. The damage induced by such hydraulic bores is often due to structural failure. Examples of devastating coastal disasters are the 2004 Indian Ocean Tsunami, 2005 Hurricane Katrina and most recently, the 2011 Tohoku Japan Tsunami. As a result, more advanced research is needed to estimate the magnitude of forces exerted on structures by such bores. This research presents results of a numerical model based on the Smoothed Particle Hydrodynamics (SPH) method which is used to simulate the impact of extreme hydrodynamic forces on shore protection walls. Typically, fluids are modeled numerically based on a Lagrangian approach, an Eulerian approach or a combination of the two. Many of the common problems that arise from using more traditional techniques can be avoided through the use of SPH-based models. Such challenges include the model computational efficiency in terms of complexity of implementation. The SPH method allows water particles to be individually modeled, each with their own characteristics, which then accurately depicts the behavior and properties of the flow field. An open source code, known as SPHysics, was used to run the simulations presented in this thesis. Several cases analysed consist of hydraulic bores impacting a flat vertical wall as well as a sloping seawall. The analysis includes comparisons of the numerical results with published experimental data. The model is shown to accurately reproduce the formation of solitary waves as well as their propagation and breaking. The impacting bore profiles as well as the resulting pressures are also efficiently simulated using the model.

Abstract:
Dissertação para obtenção do Grau de Mestre em Engenharia Civil - Perfil de Estruturas
O aprofundamento dos conhecimentos relativos ao fenómeno de galgamentos de estruturas de protecção costeira tem vindo a revelar-se importante. Esta importância tem que ver com a necessidade de proteger bens e pessoas, que actualmente, ocupam densamente as zonas costeiras. A interacção entre ondas e estruturas é um fenómeno complexo, dada a grande diversidade de parâmetros e fenómenos em causa. Entre outros, a cota do coroamento, a geometria do perfil transversal e a agitação marítima caracterizada pelas ondas de vento aparecem como factores decisivos no projecto das estruturas de protecção longitudinal aderente impermeável. Na fase inicial do projecto da estrutura recorre-se a métodos empíricos e semi-empírico e, para reduzir o grau de incerteza, recorre-se a modelação física na fase final do projecto. Com o avanço da tecnologia computacional, tem sido possível simular numericamente cenários de escoamento de fluidos, como é o caso do fenómeno de galgamento. Esta possibilidade apresenta enormes vantagens no que toca à redução de tempo e custos na fase de projecto e na optimização dos modelos físicos. No entanto, a modelação numérica ainda é tida como ferramenta complementar do modelo físico dado que os seus resultados ainda não são seguros. Neste contexto, o presente trabalho tem como foco a aplicação do programa de cálculo SPHysics como ferramenta para simular o galgamento resultante da interacção onda-estrutura. Para tal, é estudado o modelo numérico com um cenário de praia com estrutura de protecção marginal para a qual existem dados experimentais resultantes de ensaios efectuados pelo Laboratório Nacional de Engenharia Civil. O modelo numérico, para o caso estudado, representa adequadamente as séries temporais de elevação da superfície livre no modelo físico. Quanto ao cálculo do caudal médio galgado, o modelo numérico aproximou-se do modelo experimental o que permitiu simular uma proposta diferente da estrutura de modo a possibilitar a redução da cota de coroamento da mesma.

The main purposes of this study are to understand what the leukemia girl will encounter physically and psychologically during the treatment process and to explore the influences of art therapy intervention on the leukemia girl for adjusting herself to the situation physically and psychologically. During the process of the case study, the researcher could improve the experiences and abilities of art therapy intervention. Findings from the study could be of references for the medical and educational professionals. This study is to treat a 9-year-old leukemia girl as its subject by introducing an art therapy intervention mainly oriented toward the theory of Art as Therapy. By way of a case study, it is to apply interview assessment, observation and data analysis etc. to conduct this study. Principally, for each case, there is one about 30-minute session once a week with a totally 12-week individual art therapy intervention. The results of this study showed: (1) During the treatment process, the leukemia girl will encounter 12 items including: “continuity”, “activity”, “regularity”, “sense of reality”, “sleep”, “food”, “human interaction”, “emotion stability”, “initiation”, “degenerated behavior”, “sense of security” and “impulse control” etc. As for the special problems, the girl will counter 6 items including: “lying or cheating”, “having nightmare”, “screaming”, “biting nails”, “fighting or quarrelling” and “pains occurred due to no reason of treatment sessions or illnesses” etc. (2) Art therapy intervention may affect the girl’s physical and psychological adjustment in the following 7 items: “continuity”, “human interaction”, “emotion stability”, “initiation”, “sense of security”, “impulse control” and “biting nails”. And the effects of art therapy intervention in “activity”, “regularity”, “sense of reality”, “sleep”, “food”, “degenerated behavior”, “lying or cheating”, “having nightmare”, “screaming”, “fighting or quarrelling” and “pains occurred due to no reason of treatment sessions or illnesses” are not significant.

Abstract:
Development of technology to harness the vast amount of renewable energy available in nature has been ever-increasing in popularity. A worldwide desire to limit dependency on fossil fuels as a means to produce power has motivated research in solar, wind, and wave energies, as well as other clean, naturally-abundant energy sources. With a density approximately 1000 times greater than air, the energy potential of ocean water is tremendous, and it is capable of providing power to locations in which other forms of renewable energy are not applicable—namely coastal regions with minimal wind or sunshine, or offshore structures. This research details the hydro-dynamic modeling of an innovative buoy design for a wave energy harvester that converts the heaving motion of waves into electrical power. Power is generated through the use of a bi-directional turbine which is driven by the relative water velocity created by the heaving buoy. In order to predict the changing velocity profile in which the bi-directional turbine will experience, a hydro-dynamic model has been created with a smoother particle hydro-dynamics code, SPHysics. The model can accurately simulate the motion of the buoy as it is excited by various ocean waves for different ocean depths. In order to maximize the flow velocity through the turbine, various geometric parameters will be altered to attempt to have the buoy and ocean wave perfectly out of phase. Additionally, the buoys stability is studied to determine the optimal geometry to promote a vertical motion as any yaw or pitching motion can not be harnessed by the bi-directional turbine.
