This report, which will be prepared in close collaboration with UCL, will describe the morphodynamic 3Di model development as well as the results of the hydrodynamic application to tidal basins in the Wadden Sea. The data associated with this model application and validation will be publicly available.
Technical report on relevance and state-of-the-art of practical sand-mud morphodynamic modelling (se abrirá en una nueva ventana)This report will introduce the need for practical sand-mud morphodynamic models in coastal engineering practice. Practical engineering models (such as Delft3D, Telemac, Mike, XBeach) do not resolve the intra-wave sediment transport processes explicitly, and include largely empirical sediment transport formulations. This makes them computationally fast, but also challenging to use. The report will give typical examples what these models are used for (e.g. harbor channel siltation), and what issues a user then typically encounters (e.g. large model uncertainty). Furthermore, it will describe how transport of sand-mud mixtures is computed in these practical models, and what possible directions are for model improvement.
Technical report on LES of mixed-grain sand transport due to waves (se abrirá en una nueva ventana)Development of large-eddy simulation (LES) software to model turbulent oscillatory flow and sediment transport induced by waves over a flat or rippled sandy bed. The sediment transport module will have the capability to model sand composed by grains of mixed and not single size. Bed load computation will be based on empirical formulas, while suspended load based on an advection-diffusion equation for mixed-grain sand. A parallel algorithm will be developed based on MPI and OpenACC protocols. Several cases will be simulated to cover a wide range of values for the mobility parameter, as well the median diameter and the diameter standard deviation of the sediment grains. The focus is on the assessment of the diameter standard deviation on sediment mobilization and suspension.
Technical report on numerical simulations on sediment mobilisation (se abrirá en una nueva ventana)This report concerns numerical results of sediment mobilization in shear-driven (Couette) flows. Two test cases will be considered. The first one involves a granular bed and a layer of water above it, while the second one considers an initially uniform mixture of sand and water. In both cases, the two-phase system will be subject to gravity and a shear force induced by a moving upper boundary. Herein, emphasis will be placed on the study of the mechanisms responsible for mobilzation and transport of sand. Our study will be based on the two-phase flow model of Monsorno et al. (2016, JFM Vol. 808, 410-440) that can capture important features of the granular phase, such as non-Newtonian rheology, compaction and dilatancy. The governing equations will then be solved numerically via the numerical algorithm of Monsorno et al. (2018, JCP Vol. 372, 799-822).
Technical report on numerical model validation of coupled wave hydrodynamics and morphodynamics (se abrirá en una nueva ventana)The objective of this report is to validate the numerical model to demonstrate its capacity in the joint prediction of the hydrodynamics and morphodynamics of a beach profile in an episodic event. The validation process will be carried out based on existing data in the literature, and, if available at the FIHAC laboratory, specific tests will be carried out on a scale suitable for the reproduction of sediment and hydrodynamics. Due to the existence of different experiments carried out during the last decade, it is considered that there is no need to generate additional tests. Different wave conditions will be validated to consider the effect of wave characteristics on the evolution of the beach profile. It will be validated from flow velocities and concentrations in the water column, for the hydrodynamic module, and the seabed evolution, for the morphodynamic module. The validation will focus only on no-cohesive sediment.
Technical report on multi-layer shallow-water model of sediment density flows (se abrirá en una nueva ventana)The deliverable will introduce the numerical model developments performed as part of the Task. The model will be a multi-layer shallow-water model with distinct layer densities/velocities, aimed at reproducing the stratification of sediment flows. The report will present the state-of-the-art and literature review, introduce the proposed model formulation, and the associated equations, and document the developed numerical implementation, for which it is currently envisioned to rely on a Finite Volume formulation.
Technical report on analytical approach for coastal resilience evaluation (se abrirá en una nueva ventana)On the basis of recent and well-known literature works on coastal resilience, suitable indicators will be used to evaluate the resilience of several selected beaches, where the data required to define such indicators are available. The suitability of such indicators to properly describe the resilience of a beach in terms of erosion/recession and inundation will be evaluated on beaches characterized by different hydrodynamics and morphology. In particular, the chosen indicators must account for the role of the marine forcing actions (e.g., waves, tides) and the resistive/passive role of the beach (e.g., soil/sediment type, bedforms). Such analytical procedure will allow one to classify the selected beaches via a quick approach. Such indicators will be interrelated to the relationships obtained by means of the numerical investigations (D2.6).
Technical report on design of OBREC ramp (se abrirá en una nueva ventana)The first important objective is the design of a suitable ramp to be used in a shoreline wave energy converter, which will be chosen for the present project and based on the overtopping principle (OBREC). The ramp configuration will thus lead to an overtopped water volume, suitable for the required energy harvesting purposes. After a literature review concerning existing OBREC prototypes, a suitable shallow water solver will be chosen and used to analyze runup and overtopping of different ramp configurations (depending on, e.g., slope, elevation, shape), under several wave climate scenarios. The sediment transport and morphological changes induced at the ramp toe and over the ramp will also be investigated, to account for potential scouring and siltation problems. The analysis of the above scenarios will allow the design of a suitable OBREC ramp that optimize the water volumes to be used for energy harvesting purposes.
Technical report on dynamic parameterisation of structures induced turbulence (se abrirá en una nueva ventana)This is a deliverable prepared by HRW and co-supervised by UPATRAS. This report will describe the modelling of flows around structures with both CFD modelling and models based on the St. Venant equations. The differences between the model results will be used to prescribe parametrisations of the turbulence. These parameterisations aim to improve the St Venant model. Application to different geometries will be used to generalise the parameterisation as much as possible.
Technical report on evaluation of morphodynamic swash zone model with existing boundary layer sub-model (se abrirá en una nueva ventana)This is a deliverable prepared by UNOTT and co-supervised by UTWENTE. The report will present a quantitative evaluation of the prediction of the evolution of beaches in the swash zone using available formulations of the boundary layer evolution and bed shear stress to be used in hydro-morphodynamic models. Existing datasets of beach profiles and sediment transport will be used to provide reference cases. These will be simulated using existing open-source hydrodynamic solvers in which the available boundary layer sub-models will be used. The performance of each of these sub-models will be assessed by comparing the evolution of the beach profile and the quantities related to sediment transport available in the selected datasets.
Technical report on 2DH solver implementation for particle transport modeling (se abrirá en una nueva ventana)After the analysis of available depth-averaged 2DH solvers for the hydro-morphodynamics in the nearshore, DC 4 will select and implement a suitable solver with the aim to properly reproduce the suspended transport of particles (e.g., sediments, pollutants) in the coastal region. The operation will be carried out, e.g., through the discretization of the advection-diffusion equation and the parameterization of suitable formulations to describe the particle erosion and deposition. Such model will be initially tested using simple cases from literature and publicly available data, with the aim to investigate the benefits of the implemented solver with respect to the previous model versions.
