Abstract:
The performance of three different hydrodynamic modelling packages is compared in this study, namely Delft3D, Delft3D FM (both developed by Deltares) and MIKE 21 FM (developed by DHI). Delft3D and MIKE 21 FM are internationally known software packages while Delft3D FM (formerly known as D-Flow FM) is a relatively new package. The models use structured approaches (Delft3D), unstructured approaches utilising triangular and quadrilateral elements (MIKE 21 FM) and unstructured approaches utilising elements ranging from linear to six sided (Delft3D FM). Models of Western Port, Australia, were developed using the three different packages to allow a comparison of performance and to determine if there are any differences in using structured versus unstructured approaches. Model performance has been assessed based on model calibration, representation of channel flows and computational efficiency. Despite the inherent differences in the grid configuration and the implementation of the numerical schemes between structured and unstructured approaches, both approaches have been shown to be able to accurately predict hydrodynamic conditions in a complex estuarine environment. The unstructured approach was found to be the most computationally efficient both when run on multiple cores (MIKE 21 FM was the most efficient) and when run on a single core (Delft3D FM was the most efficient).

Abstract:
Abstract Coastal regions are increasingly vulnerable to damage from storm surge and inundation. Delft3D is used by the Naval Oceanographic Office to model the ocean dynamics in the near shore. In this study, the performance of Delft3D in predicting the surge and inundation during Hurricane Ike, which impacted the northern Gulf of Mexico in September 2008, is examined. Wave height, water level, and high-water mark comparisons with a number of observations confirm that the model does well in predicting the surge and inundation during extreme events. The impact of using forecast winds based on the best-track data as opposed to hindcast winds is also investigated, and it is found that the extent of inundation is represented reasonably well with the forecast winds. In Delft3D, waves can be coupled to the hydrodynamic component using the radiation stress gradient method or the dissipation method. Comparing the results of using the two shows that for low-resolution grids such as that needed for a forecast model the dissipation method works better at reproducing the water levels and inundation.

Abstract:
A comparison between two very different numerical models is presented: Delft3D and XBeach. Delft3D (Deltares) calculates non-steady flow and transport phenomena that result from tidal and meteorological forcing. The wave propagation is calculated in the frequency domain. XBeach (Unesco-IHE, Delft University and Deltares) consists of formulations for short wave envelope propagation (time-dependent wave action balance), non-stationary shallow water equations, sediment transport and bed update. The model is able to resolve the time dependent long waves, which are important in the surf zone. A number of simplified cases are defined beforehand taking into account actual features and conditions existing in chosen problem areas. The examination of these simplified cases allows for the identification of driving processes and the assessment of the sensitivity to certain relevant parameters, with the advantage of working in scenarios of limited complexity and without excessive computational load.

Abstract:
The modeling of bar dynamics is crucial for understanding coastal dynamics and shoreface nourishment evolution. Due to the complexity and variability of the physical processes involved, the formulations developed within the process-based numerical modelling system Delft3D for representing the forcing of the morphodynamic processes (waves, currents, sand transport) contain a high number of calibration parameters. Therefore, the setting up of any Delft3D computation requires a tedious calibration work, usually carried out manually and therefore by definition subjective. The aim of this work is the setting up of an automated and objective calibration procedure for Delft3D morphodynamic computations. A number of calibration parameters have been identified based on a careful sensitivity analysis. The calibration method named DUD (Does not Use Derivatives) is selected and coupled to a alongshore uniform Delft3D model. The validity of the implementation is shown based on synthetic tests (twin experiments). The validation test is carried out using field data collected at Egmond-aan-Zee (The Netherlands). This paper shows that the tool can be successfully used to calibrate Delft3D. However, further research is especially required to understand whether the computed parameters settings only simulate the best morphodynamic evolution of the bars or also describe properly the underlying physical processes.

Abstract:
We present a model for the morphodynamics of tidal basin-inlet-delta systems at the centennial time scales. Tidal flow is calculated through a friction dominated model, with a semi-empirical correction to account for the advection of momentum. Transport of non-cohesive sediment (sand) is simulated through tidal dispersion, i.e., without explicitly resolving sediment advection. Sediment is also transported downslope through a bed elevation diffusion process. The model is compared to a high-resolution tide-resolving model (Delft3D) with good agreement for different hydrodynamic and sedimentary settings. The model has low sensitivity with respect to temporal and spatial discretization. For the same spatial resolution, the model is about five orders of magnitude faster than tide-resolving models (e.g., Delft3D), and about three orders of magnitude faster than tide-resolving models that use a morphological acceleration factor. This numerical efficiency makes the model suitable to assess long-term changes of large coastal areas. The model’s simplicity makes it suitable for coupling with other physical, ecological, and socio-economic dynamics.

Abstract:
This study aims at hydrodynamic modelling of Bow River, which passes through the City of Calgary, Canada. Bow River has a mobile gravel bed. Erosion and deposition processes were exacerbated by a catastrophic flood in 2013. Channel banks were eroded at various locations, and large gravel bars formed, which could lead to water level changes and accordingly more flooding. This study investigates the performance of Delft3D-Flow and MIKE 21 FM to simulate the hydrodynamics of the river during the 2013 flood. MIKE 21FM employs unstructured triangular mesh while Delft3D-Flow model uses curvilinear structured grids. Performance of each model was evaluated by the available historical water levels. The results of this study demonstrated that, with approximately the same averaged grid resolution, MIKE 21 FM resulted in more accurate results with a higher computational cost compared to the Delft3DFlow model. It was shown that Delft3D-Flow model may require higher grid cell resolution to result in comparably same depth-averaged velocities throughout the study area. However, considering the balance between the computational cost and the accuracy of the results, both models were capable to adequately replicate the hydrodynamics of the river during the 2013 flood. Results of statistical KS and ANOVA test analysis showed that the model predictions were sensitive to the horizontal eddy viscosity and the Manning roughness. This confirms the necessity of an appropriate calibration of the generated numerical models. The findings of this study shed light on the Bow River flood modelling, which can guide flood management.

Abstract:
As the forecasting models become more sophisticated in their physics and possible depictions of the nearshore hydrodynamics, they also become increasingly sensitive to errors in the inputs, such as errors in the specification of boundary information (lateral boundary conditions, initial boundary conditions, etc). Evaluation of the errors on the boundary is less straightforward, and is the subject of this study. The model under investigation herein is the Delft3D modeling suite, developed at Deltares (formerly Delft Hydraulics) in Delft, the Netherlands. Coupling of the wave (SWAN) and hydrodynamic (FLOW) model requires care at the lateral boundaries in order to balance run time and error growth. To this extent, we will use perturbation method and spatio-temporal analysis method such as Empirical Orthogonal Function (EOF) analysis to determine the various scales of motion in the flow field and the extent of their response to imposed boundary errors.

Tsunami inundation was successfully reproduced for the Galle City, Sri Lanka using Delft3D-Flow model and Delft Dashboard Tsunami Tool. Previously identified tsunami hazard maps agreed with the simulation results. Existing tsunami early warning system and preparedness for evacuation are in a favourable condition. Based on the outcome of numerical simulation and field investigations, suitable horizontal evacuation measures were proposed, and vertical evacuation points were suggested primarily considering the identified hazardous zones with lack of proposed buildings and evacuation routes in previous studies.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/g4V0c8GQepE

Abstract:
The coupled Delft3D-object model has been developed to predict the mobility and burial of objects on sandy seafloors. The Delft3D model is used to predict seabed environmental factors such as currents, waves (peak wave period, significant wave height, wave direction), water level, sediment transport, and seabed change, which are taken as the forcing term to the object model consisting of three components: (a) physical parameters such as diameter, length, mass, and rolling moment; (b) dynamics of the rolling cylinder around its major axis; (c) an empirical sediment scour model with re-exposure parameterization. The model is compared with the observational data collected from a field experiment from 21 April to 13 May 2013 off the coast of Panama City, Florida. The experimental data contain both object mobility using sector scanning sonars and maintenance divers as well as simultaneous environmental time series data of the boundary layer hydrodynamics and sediment transport conditions. Comparison between modeled and observed data clearly shows the model’s capabilities and limitations.

Abstract:
In contrast to the efforts made to develop hydrodynamic models for large-scale tsunami propagation and run-up, little has been done to develop, test, and validate sediment transport models used to simulate tsunami-induced sediment movement. In this study, the performances of six widely-used sediment transport formulas are evaluated through case studies using an open source code XBeach, which is based on 2D depth-averaged nonlinear shallow water equations. Another open source code, Delft3D, is also used to see to what extent XBeach can give reliable results. The benchmarks used for case studies include three laboratory experiments and one field observation from a post-tsunami field survey conducted after the 2004 Indian tsunami. Our results show that most of the surveyed sediment transport formulas can give good results for laboratory-scale problems, but for real-scale problems, all six formulas failed to produce good results compared to those found in laboratory conditions. For laboratory-scale problems, both XBeach and Delft3D can predict satisfactory results with properly-chosen model parameters. For real tsunamis, high suspended sediment concentration may occur, and density stratification and hindered settling effect play an important role; therefore, Delft3D, with both hindered settling and density stratification being considered, may perform better than XBeach. The findings reported here will be useful for researchers and practitioners working on tsunami hazard mitigation.

Abstract:
Cross-shore wave transformation, nearshore currents, and morphology model predictions using Delft3D are compared with comprehensive observations acquired on a barred beach at Duck, North Carolina over a wide range of conditions. The Delft3D 2-DH model utilizes shallow water equations to phase resolve the mean and infragravity motions in combination with an advection diffusion equation for the sediment transport. Model coefficients and the effect of small changes in the wave incidence angle were examined for model sensitivity. The wave transformation model is dependent on the breaking parameter Y , which determines organized wave energy dissipation. Y was found to increase as a function of offshore H(sub rms). However, this is robust and a model skill of .89 was obtained using a constant Y = .425. The manning number n affects the current bed shear stress and determines the model current magnitude having an optimal value of n = 0.02. The model is not overly sensitive to the value of n. The asymmetry coefficient a(sub w) determines the amount of onshore sediment movement. The rip channel created by mean currents on a short time scale is not affected by a(sub w) whereas bar evolution requires more time to develop allowing a(sub w) to affect morphology. A values of a(sub w) = .25 gave the best results. Further research is needed to calibrate this parameter. Small changes in wave angle can cause significant errors for currents when complex bathymetry is present and the waves are near shore normal. Overall the model is robust with sensitivity to small changes in near normal wave angles.

Os modelos numéricos se propõem a simular tanto os processos de transporte como os processos químicos que ocorrem num corpo hídrico. O objetivo deste trabalho é avaliar os processos que determinam a qualidade das águas da Lagoa dos P atos, utilizando pela primeira vez o modelo Delft3D da WL | Delft Hydraulics. Neste modelo foram aplicados os dados obtidos no Programa para o Desenvolvimento Racional, Recuperação e Gerenciamento Ambiental da Lagoa dos Patos/Mirim – Pró Mar de Dentro, que realizou onze cruzeiros de amostragem, durante o período compreendido entre fevereiro de 1999 e janeiro de 2000. A primeira etapa realizada foi a validação do modelo hidrodinâmico, que foi feita comparando-se os dados de salinidade obtidos em campo ao longo da Lagoa com os resultados das simulações. Em seguida, com o modelo hidrodinâmico validado, foi aplicado o modelo de qualidade de água. Os seguintes parâmetros foram avaliados: material em suspensão, oxigênio dissolvido, DBO, nitrato, nitrito, amônio, nitrogênio total, fosfato, fósforo total, carbono orgânico total, sílica, cromo, cobre, zinco, chumbo, níquel, cádmio, ferro. Os resultados mostraram que o modelo foi validado, apresentando bons resultados na simulação da circulação da Lagoa dos Patos. Apesar de alguns desvios terem sido percebidos, não se deveram propriamente ao modelo e sim a ausência de uma melhor distribuição temporal e espacial de dados para alimentá-lo. A avaliação dos parâmetros de qualidade de água indicou que os processos químicos e físicos que ocorrem na Lagoa variam espacialmente e temporalmente, dependendo principalmente das condições metereológicas da região. Apesar das diversas influências antrópicas presentes na Lagoa dos Patos, as águas do eixo principal da Lagoa não apresentaram sérias contaminações que tragam riscos aos ecossistemas que a cercam e dela dependem. De acordo com os resultados obtidos, o modelo poderia tornar-se uma importante ferramenta na previsão e avaliação da qualidade da água da Lagoa dos Patos.
Numeric models intend to simulate both the transport and chemical processes that happen in a water body. The aim of this work is to evaluate the processes that govern the quality of the Patos Lagoon water, using for the first time Delft3D model, from WL | Delft Hydraulics. The model was applied using data obtained during the project denominated “Programa para o Desenvolvimento Racional, Recuperação e Gerenciamento Ambiental da Lagoa dos Patos/Mirim – Pró Mar de Dentro”, wich carried out eleven sampling campaigns, during the period of February 1999 and January 2000. First stage, consisted hydrodynamic model validation, that was made comparing the salinity data obtained during the samplig with the simulations results. Second stage, with the hydrodynamic model validated, the water quality model was applied. The following parameters were evaluated: suspended matter, dissolved oxygen, BOD, nitrate, nitrito, ammonium, total nitrogen, phosphate, total phosphorous, total organic carbon, silicate, chromium, copper, zinc, lead, nickel, cadmium, iron. The results showed that the model was validated, presenting good results in the circulation simulation of the Patos Lagoon. In spite of some deviations have been observed, they were not due properly to the model, but due the absence of more precise data for apply in the model. The evaluation of the water quality parameters indicated that chemical and physical processes that happen in the Lagoon have variation in the space and in the time, mainly depending on the metereological conditions of the region. In spite of several antropogenics influences present in the Patos Lagoon, waters in your main axis didn't present contaminations that bring risks to the survival of the ecossystems that surround and depend on this Lagoon. According to the obtained results, the model could become an important tool in the forecast and evaluation of the water quality of the Patos Lagoon.

Abstract:
To accommodate an increasing number of tourists visiting Bequia, the second largest island of Saint-Vincent and the Grenadines, the local government constructed an airport, through a major coastline land-reclamation project. However, due to the prevailing ocean current patterns in the area, an inlet created on the east side of the new airport is prone to trapping significant amounts of ocean-borne debris. This litter accumulation creates a health risk to local fishermen who clean their daily catch using water from the inlet. It is proposed to install a rubble-mound groyne structure on the eastward side of the new inlet to address this problem. The utilisation of a coastline groyne in this case is somewhat unorthodox, as the latter is normally employed to mitigate against coastal erosion. The goal of this study is to optimise the groyne design with the assistance of a 3D numerical model. The ‘Delft3D’ open-source model (WAVE and FLOW modules) was selected to examine the effects of different orientations and lengths of the proposed groyne on the movements of floating debris. Included in the initial phase of the study was a field investigation to collect certain data which were necessary for model calibration and validation. This involves the use of an Acoustic Doppler Current Profiler (ADCP) to measure local shore bathymetry and also current velocities over a range of tidal cycles.

Abstract:
The stratified flow of the lower Mississippi River due to density gradients is a well documented phenomenon. This stratification of fresh and saline water manifests itself as a heavier wedge of saline water that extends upriver and a buoyant fresh water plume extending into the Gulf of Mexico past the Southwest Pass jetties. The maximum absolute distance of saltwater intrusion observed anywhere in the world occurred on the Mississippi River in 1939 and 1940 when saltwater was observed approximately 225 km upstream from the mouth of Southwest Pass. The U. S. Army Corps of Engineers now prevents the wedge from migrating upstream by constructing a subaqueous barrier in the river channel. A curvilinear grid was constructed representative of the modern Mississippi River delta. Boundary conditions were developed for the drought year of 2012 and the grid was tested in order to evaluate the salinity intrusion and sediment transport abilities of the Cartesian Z-coordinate Delft3D code. The Z-model proved to have the ability to propagate the saline density current as observed in the prototype. The effect of salinity on fine sediment transport is evaluated by manipulation of the settling velocity through a cosine function provided in the model code. Manipulation of the fine sediment fall velocity through the cosine function was an effective means to simulate the re-circulation of flocculated sediments in the saline wedge turbidity maxima. In addition, the Z-model capably reproduced the fine sediment concentration profiles in a fully turbulent shear flow environment. With the ability to reproduce the seasonal saline density current and its effect on sedimentation within the turbidity maxima as well as sedimentation characteristics in a fully turbulent shear flow, a model capable of analyzing all of the major processes affecting fine sediment transport within the Mississippi River salt wedge estuary has been developed.

Full text
Abstract:
A three dimensional time-dependent coupled ecosystem model is applied to Izmir Bay for the first time. Delft3D modelling suite&rsquo
s FLOW and ECO modules are adapted and tuned for the region. A reference model with a time frame of three years is produced that represents the current physical and biogeochemical status of the bay. Model skill assessment methods are used as a measure of model performance and to address the shortcomings of it. The hydrodynamics model is able to produce physical features in terms of seasonality and spatial distribution within reasonable ranges, whereas the ecosystem model has certain discrepancies which can be reduced with improved quality of model inputs, such as open boundary conditions, and fresh water and nutrient fluxes. The reference model is used as a tool with predictive capacity to assess the ecosystem response of the bay to possible changes it may undergo in the future. Five nutrient enrichment/reduction scenarios are constructed to predict the reactions of the bay to changing external inputs of DIN and PO4. Results suggest that both physical and biogeochemical properties of the bay show strong horizontal gradients between outer and inner regions in which both natural and anthropogenic influences are effective. It is revealed that Outer bays are mostly occupied by waters originating from the oligotrophic Aegean Sea, while eutrophicated inner regions are mainly controlled by local influences such as increased fresh water inputs and excessive wastewater discharges. Results of the nutrient enrichment/reduction scenarios suggest that the N-limited Inner and Middle bays and the P-limited Outer bays, give contrasting reactions to changes in inputs of DIN and PO4 such that the former is more sensitive to DIN input whereas the latter is more sensitive to PO4 input. Due to the existence of these two contrasting environments in the bay, availability of one nutrient is dependent on the availability of the other, therefore treatment of both should be considered in parallel. Among the scenarios tested in this study, the best possible option to reduce eutrophication in Izmir Bay is to prevent the increase of PO4 input and to reduce the DIN input simultaneously. These outcomes are aimed to provide a scientific insight for coastal policy makers and environmental managers on how changes in anthropogenic influences can impact the marine ecosystem of the bay.

Abstract:
Desde 1960, a cidade de Balneário Camboriú, localizada no litoral centro-norte do estado de Santa Catarina, vem sofrendo intensa urbanização de forma não planejada, resultando em problemas que apresentam um impacto negativo ao turismo, principalmente relacionados à superlotação no verão e ao sombreamento da praia no período da tarde, devido à grande quantidade de edifícios altos na beira mar. Buscando ampliar o espaço físico da orla, a Prefeitura Municipal de Balneário Camboriú está desenvolvendo o projeto de alimentação artificial da Praia Central do município, que prevê uma nova largura da faixa de areia de 100 m. Este trabalho descreve, através da análise dos processos físicos, os possíveis impactos advindos da implementação da obra de aterro hidráulico, utilizando o modelo numérico Delft3D. O trabalho de investigação foi separado em três tópicos: (1) propagação de ondas, (2) processos hidrodinâmicos e (3) variações morfológicas, em dois cenários: atual e posterior à alimentação artificial. Os resultados da modelagem de propagação de ondas demonstraram maior energia na porção norte da enseada, sendo a porção sul mais abrigada. Comparando os cenários observa-se uma diminuição na energia de onda em águas rasas devido à nova configuração da costa, principalmente na porção norte da enseada. Os resultados do modelo hidrodinâmico, mostraram que posteriormente a alimentação da praia, as correntes sofrem intensificação na nova zona de arrebentação de ondas, a qual se desenvolverá numa região em que, no cenário atual, as velocidades das correntes litorâneas são muito baixas. A análise dos potenciais impactos na morfologia litorânea demonstrou que as variações morfológicas ocorrerão devido à reorganização do ambiente diante da nova configuração batimétrica da enseada, sendo que a formação dos bancos longitudinais se deslocará em direção ao mar. Não foram observadas áreas de erosão entre o cenário atual e o cenário futuro, demonstrando que a enseada deverá se comportar como um sistema fechado. De modo geral a modelagem numérica demonstrou que os processos futuros reproduzirão aqueles que ocorrem no cenário atual, porém, estarão mais afastados, a cerca de 100 metros à frente, em direção ao mar.
Since 1960, Balneário Camboriú, located on the north-central coast of Santa Catarina, Brazil, has been suffering from an unplanned intense urbanization, resulting in negative impacts on tourism, mainly related to overcrowding during the summer and shading on the beach in the afternoon due to lots of tall buildings in the seafront. Aiming to enlarge the area available for recreational beach use, the city government of Balneário Camboriú is developing the nourishment project of the city's Central Beach, which provides a new sand stretch width of 100 m. This paper describes, through the analysis of physical processes, the possible impacts of the nourishment, using the numerical model Delft3D. The analysis distinguishes three steps: (1) wave propagation, (2) hydrodynamic processes, and (3) morphological variations, in two different scenarios: before and after the beach nourishment. The results of the wave propagation modeling shows the occurrence of greater energy in the northern portion of the bay, with a more sheltered southern portion. Comparing the scenarios it is observed a decrease in wave energy in shallow water due to the new configuration of the coast, especially in the northern part of the bay. Results from the hydrodynamic model indicate that after the beach nourishment the currents are intensified in the new waves surf zone, which will be developed in a region where, in the present scenario, the alongshore currents velocities are very low. The analysis of the potential impacts on coastal morphology showed that morphological changes will occur due to the reorganization of the place because of the new bay bathymetric configuration, since the longitudinal banks formation will move towards the sea. No erosion areas between the present and future scenario were observed, proving that the bay shall behave as a closed system. Overall the numerical modeling showed that future processes will reproduce those that occur in the present scenario, however the process will occur about 100 meters ahead, towards the sea.

Abstract:
Este trabalho teve como objetivo analisar os possíveis efeitos de um aumento do nível do mar no padrão de correntes no Sistema Estuarino de Santos (SP), através do uso do modelo hidrodinâmico do Delft3D-FLOW, considerando diferentes taxas de aumento de acordo com o quinto relatório do Intergovernmental Panel on Climate Change (AR5). Os resultados indicam alteração na velocidade da corrente ao longo do domínio implementado, mais evidente durante a sizígia. Observa-se um aumento da magnitude da corrente em praticamente todo o Canal de São Vicente e redução da magnitude nos canais do Porto de Santos, canal de Bertioga e na região interna do Estuário de Santos. Os resultados do modelo numérico foram comparados com diversos dados coletados na região de estudo e verificou-se a correta representação dos padrões de circulação da área. Este estudo comprovou a importância de utilizarmos resultados de um modelo de maior escala (HYCOM) como forçantes, através da condição de fronteira denominada Riemann, permitindo que o modelo represente fenômenos de baixa frequência, que geram circulações e variações do nível do mar com a mesma ordem de grandeza dos efeitos da maré astronômica na área de estudo.
This study aimed to analyze the possible effects of a sea level rise in Sistema Estuarino de Santos (SP) circulation pattern, through the use of Delft3D-FLOW Hydrodynamic Model considering different elevation rates according to Intergovernmental Panel on Climate Change fifth report (AR5). The results indicate change in the current\'s magnitude, being more evident during the spring tide. There is an increase in the velocity practically all over São Vicente Channel and the reduction of magnitude in the Porto de Santos and Bertioga channels and in the inner region of the estuary. The numerical model results were compared with several measured data and it was verified that the model correctly representats the circulation patterns of the area. This study proved the importance of using results of a larger scale model (HYCOM), forced through a boundary condition called Riemann, allowing the model to represent low frequency phenomena, which generate sea level variations with the same order of magnitude of the effects of the astronomical tide in the study area.

Abstract:
The braided rivers and floodplains in the Upper Waitaki Basin (UWB) of the South Island of New Zealand are critical habitats for endangered and threatened fauna such as the black stilt. However, this habitat has degraded due to introduced predators, hydropower operations, and invasive weeds including Russell lupins. While conservation efforts have been made to restore these habitats, flood events may provide a natural mechanism for removal of invasive vegetation and re-creation of natural floodplain habitats. However, little is understood about the hydraulic effects of floods on vegetation and potential mortality in these dynamic systems. Therefore, this thesis analyzed the flood-induced processes that cause lupin mortality in a reach of the Ahuriri River in the UWB, and simulated various sized flood events to assess how and where these processes occurred. To determine the processes that cause lupin mortality, post-flood observations were utilized to develop the hypothesis that flood-induced drag, erosion, sediment deposition, inundation, and trauma were responsible. Field and laboratory experiments were conducted to evaluate and quantify these individual processes, and results showed that drag, erosion, sediment deposition and inundation could cause lupin mortality. Utilizing these mortality processes, mortality thresholds of velocity, water depth, inundation duration, and morphologic changes were estimated through data analysis and evaluation of various empirical relationships. Delft3D was the numerical model used to simulate 2-dimensional flood hydraulics in the study-reach and was calibrated in three stages for hydraulics, vegetation, and morphology. Hydraulic calibration was achieved using the study-reach topography captured by Structure-from-Motion (SfM) and various hydraulic data (depth, velocity, and water extent from aerial photographs). Vegetation inclusion in Delft3D was possible utilizing a function called ‘trachytopes’, which represented vegetation roughness and flow resistance and was calibrated utilizing data from a lupin-altered flow conveyance experiment. Morphologic calibration was achieved by simulating an observed near-mean annual flood event (209 m3 s-1) and adjusting the model parameters until the simulated morphologic changes best represented the observed morphologic changes captured by pre- and post-flood SfM digital elevation models. Calibration results showed that hydraulics were well represented, vegetation inclusion often improved the simulated water inundation extent accuracy at high flows, but that local erosion and sediment deposition were difficult to replicate. Simulation of morphological change was expected to be limited due to simplistic bank erosion prediction methods. Nevertheless, the model was considered adequate since simulated total bank erosion was comparable to that observed and realistic river characteristics (riffles, pools, and channel width) were produced. Flood events ranging from the 2- to 500-year flood were simulated with the calibrated model, and lupin mortality was estimated using simulation results with the lupin mortality thresholds. Results showed that various degrees of lupin mortality occurred for the different flood events, but that the dominant mortality processes fluctuated between erosion, drag, and inundation. Sediment deposition-induced mortality was minimal, but was likely under-represented in the modeling due to poor model sediment deposition replication and possibly over-restrictive deposition mortality thresholds. The research presented in this thesis provided greater understanding of how natural flood events restore and preserve the floodplain habitats of the UWB and can be used to aid current and future braided river conservation and restoration efforts.

Abstract:
Natural and anthropogenic processes over the past 150 years have altered the bathymetry of the Lower Columbia River (LCR) and have changed the long wave propagation of tides and floods. Possible causes for the increase in tidal amplitudes (+7% in tidal range in Astoria) are decreases in river discharge, lengthening of the river channel due to the construction of jetties at the mouth, dredging and deepening of the shipping channel, and reduction of the tidal prism due to the filling and diking of tidal wetlands. In this study, changes in the characteristics of long waves are elucidated by developing two hydrodynamic models of the LCR which reflect historical and modern bathymetric conditions and forcing. The historic model simulates late 19th century conditions and is extensively validated using recently recovered tide records along the LCR (e.g., Astoria, 1853-1876) and river stage measurements (e.g., Portland, 1876-1964). Results suggest that water levels in Portland at low river discharge are up to 0.5-1.0m lower than in the past. However, historical water levels during a flood scenario based on the 1880 spring freshet are similar to modern water levels. Since tidal range in the modern scenario is persistently higher at all locations, the flood risk in many locations along the LCR has increased for the same boundary conditions. The results are explained by considering the governing equations of momentum and mass-conservation. At low river flow, greater depth leads to reduced frictional effects, producing amplified tidal range and tidal velocities but a decreased river slope (and lower Portland water levels). At high flow, the modern flood is confined by dikes and the loss of wetlands, which counteracts the effect of decreased friction. Nonetheless, the high friction of the historical wooded floodplain also confined the historical flood path. Hence, historical and modern flood heights are surprisingly similar, though scaling analysis suggests that the historical flood wave was more diffusive.

Abstract:
This chapter shows that a parallel framing of the Indies as a missionary field was crucial in informing, and sometimes challenging the colonial enterprises. In many instances, Dutch missionaries saw a chance for Christianizing the natives given what appeared to them as the natives' weak understanding and practice of Islam, arguing that the Javanese could not be considered Muslims for their “Islam” fell far short of the Islam they knew from the texts edited by their teachers in Delft. More crucially, however, one can see in their writings tangential and certainly unintended evidence of an active engagement with new modes of thinking, with printing, and with Sufi practices imported from the Middle East—practices that were leading some Javanese to label their neighbors ruddy abangan (red ones) while they themselves identified as spotless putihan (white ones). If anything was clear by 1888, it was that Dutch knowledge of Islam was outdated and far too oriented towards texts above contexts.

Abstract:
Numerical modelling of ice growth and transport on regional scales such as lakes, estuaries, or coastal seas can provide crucial input for the planning and design of offshore structures in arctic, sub-arctic, or even mid-latitude regions. It is in these regions that the total loading of ice on infrastructure such as platforms, sea defense structures, sub-sea pipelines, or wind turbines may exceed the total loading of waves and currents, and may therefore determine the design. Thus, the interaction of ice with planned structures might be significant, and accurate models of ice dynamics would be invaluable to engineering in these regions. There is, however, a general lack of ice models that can be applied to study these complex integral physical processes at regional scales. Typically, ice modelling focusses on either large oceanic scales using climate models, or on local scales to study small-scale ice-structure interactions. The regional scale model presented in this paper is targeted at bridging this scale gap. This paper describes the implementation of an ice module in Delft3D. Delft3D is a flexible integrated modelling suite, which simulates two- and three-dimensional flow, sediment transport, morphology, waves, spills, water quality, and ecology, and is capable of handling the interactions between these processes. By dynamically coupling an ice module with these existing modules it becomes possible to not only predict the growth, melting, and transport of open-water ice and associated hydrodynamics, but also to study the interaction of ice with, for example, river banks, the seabed, water quality, or spills of fine sediments or oil. This paper presents the major concepts of the new Delft3D ice module, as well as example applications for various lakes in The Netherlands and Fountain Lake, in Minnesota, USA. Finally, a hypothetical case of ice transport modelling is presented.

Abstract:
The Petrobras energy company plans to build a new terminal in the Baía de Todos os Santos, Brazil. This paper describes a study in which an estimate has been provided for infragravity (or low-frequency, LF) wave conditions at this future LNG Regasification Terminal location. To aid the design of the terminal, numerical simulations of the propagation of these waves into the bay have been performed. At the proposed terminal location, within a large coastal bay, LF waves can be related to long waves bound to the local primary sea and swell waves (bound LF waves) and to low-frequency waves that propagate into the bay after being made free near the bay entrance (free LF waves). While most of the primary waves will not fully penetrate into the bay, the long LF waves can. Due to the large area of the bay (approximately 40 km × 30 km), detailed modelling of all complex coastal processes related to infragravity waves was not efficient. Therefore, a practical approach has been followed in this study. For a first evaluation, an estimate has been made of bound LF wave conditions at the terminal location inside the bay and at the mouth of the bay. This estimate is based on an equilibrium method using the local primary wave climate and assuming a flat bottom. In a second stage, free LF wave penetration into the bay has been simulated using the shallowwater model Delft3D-FLOW. By applying the practical approach described in this paper, infragravity wave conditions (bound and free) have been efficiently estimated at the future terminal location for yearly-averaged and extreme primary wave conditions. The results show that the LF wave climate at the terminal will be very mild, corresponding to beneficial conditions for terminal operations. The outcome of this study will be taken into account in the further design of the terminal.

Abstract:
Abstract Maintaining and retaining a quality sandy beach is a primary requirement for attracting people and tourists in any coastal country. Tourism Enterprises Company (TEC) in Kuwait owns 230 m long sandy beach in Ras Al-Ardh Sea Club, Salmiya, Kuwait. The beach has been eroding because of strong hydrodynamics forces from waves and currents. TEC wants to develop a stable sandy beach of 30 m wide. Kuwait Institute for Scientific Research (KISR), Kuwait is assigned to carry out the required scientific studies. In order to make sure a stable quality beach will exist, KISR has carried out the needed studies, which involves the field measurements such as bbathymetry survey, current and tidal variations, physical characteristics of beach soil, beach and sea bed profile, establishing the design parameters such as waves, currents, tide and wind. Hydrodynamic model study using DELFT3D model for the present and for the proposed extended groin conditions with beach nourishment were carried out. Also numerical modeling using GENESIS model to understand the future shore line changes due to the proposed development was carried out. Design of Groins to estimate the weight of armor units and weight of inner layers were carried out. The particle size and quantity of sand needed for reclamation of 30 m wide beach was estimated. Based on the study, it is recommended that the sandy soil to be used for 30 m wide beach nourishment should have D50 greater than 0.42 mm (say 0.5 mm) and D10 greater than 0.25 mm. The borrow pit much be selected by keeping this soil characters in mind. It is recommended to use a submerged offshore breakwater in order to retain the beach sand in place and for reducing the maintenance nourishment. Otherwise, large quantity of the capital nourished beach sand will escape into the deeper water due to strong current coupled with waves and steep seabed slopes. Environmental Impact Study was carried out as per Kuwait Environment Public Authority requirements to bring out the impacts due to beach filling and the construction submerged offshore barrier and extension of east groin for a distance of 30 m. TEC will implement the recommendations for developing the beach in Ras Al-Ardh sea club and will be useful to attract more people to use this beach.
