Scaling and production of first year ridges in ice basins, ice ridge interaction with conical structures

Dr. Aleksey Shestov, Researcher Svalbard Science Centre, Longyearbyen, Norway

There is a relatively high uncertainty in the prediction of ridge loads. These experiments will give important input to the development of guidelines on how to scale and produce first-year ice ridges in scale-model tests. The tests will give information on how steep cones may perform in ridge interaction, in other words answer the question: will the forces be less than on a cylindrical structure?

The dynamics of bi-directional exchange flows: implication for morphodynamic change within estuaries and sea straits

Dr. Claudia Adduce Ass. Prof. University of Rome Tre, Italy

To model idealized representations of bi-directional, stratified, exchange flows through non-erodible and erodible channel topographies and fill existing knowledge gaps associated with:

(i) improved physical understanding of exchange flow bathymetry feedback mechanisms in channels with erodible boundaries;

(ii) better representation of interfacial mixing, secondary flow circulations and near-bed boundary dynamics for numerical modelling simulations of exchange flow processes in estuaries and sea straits;

(iii) enhanced understanding of other external parametric influences (i.e. tidal/freshwater forcing; density differences; bed friction and Coriolis effects) on the nature of these exchange flow-bathymetry interactions.

Topographic barriers and warm ocean currents
controlling Antarctic ice shelf melting

Dr. Elin Darelius
Geophysical Institute, University of Bergen

The melting of the Antarctic ice shelves at the contact of a warming ocean would lead to an alarming sea level rise. This process is controlled by the penetration under the ice shelf of water currents of different densities, with strong constraints brought by the Coriolis force and by bottom topography. The experiments performed on the Coriolis platform provide reduced scale models of these complex effects.

The Adriatic-Ionian Bimodal Oscillating System (BiOS-CRoPEx)

Dr. Miroslav Gačić
Instituto Nazionale di Oceanografia e di Geofisica Sperimentale, Sgonico (TS), Italy

To show from the physical modelling exercises that the inversions of the North Ionian Gyre (NIG) circulation in an idealized Adriatic-Ionian/Eastern Mediterranean circulation system can be generated only by changing the inflowing water density (from the Adriatic) with respect to the residing water in the Ionian basin.

Laboratory modeling of gap-leaping and intruding western boundary currents under different climate change scenarios

Prof. Stefano Pierini
Dept of Science and Technology, Parthenope University of Naples, Italy

To investigate the interaction of a boundary current with a gap along the coast. The great relevance of the problem calls for ad hoc laboratory experiments, which require large scale simulations and, in turn, a large rotating tank facility such as that available at LEGI



Shallow wave basin

Waves plus currents INteracting at a right anGle over rough bedS (WINGS)

Prof. Carla Faraci, Associate Professor, University of Messina, Italy

A detailed experimental campaign intended to investigate the near bed flow in the presence of different roughness conditions (loose sand, gravel, fixed ripples) with waves and currents crossing at a right angle.
To understand how the combined flow will affect the velocity distribution along the water column and the apparent bed roughness.



Large scale deep water wave basin

Spar Buoy for Offshore Floating Wind Energy Conversion

Prof. Giuseppe Roberto Tomasicchio, University of Salento, Lecce, Italy

The use of renewable energy is a key point to reach the objectives of the Paris UN Climate Change Conference December 2015.
The project intends to improve the understanding of the dynamic response of floating offshore wind turbines under combined wind and wave conditions in deep water due to the need of their cost effective design.

Hydrodynamics at coastal wetland edges

Dr. Lucy Gwen Gillis, Leibniz-Zentrum für Marine Tropenökologie, Bremen, Germany

Coastal wetlands provide important ecosystem services for coastal protection by trapping sediments, attenuating waves and slowing currents.
Those wetlands can be used for defence against coastal flooding and tsunamis. The project aims to contribute to the better understanding of aggradation (vertical growth) and progradation (horizontal, seaward growth) of coastal wetlands.

Tsunamis due to ice masses: Different calving mechanisms and linkage to landslide-tsunamis

Dr. Valentin Heller, Assistant Professor in Hydraulics, University of Nottingham

Understanding tsunami hazard due to ice mass fall, which (may) generate waves and splashes exceeding tens of meters in height. These waves pose a considerable hazard for the local community, the fishing industry and tourists.



Deltares / Delta Basin

Wave overtopping of coastal defences under directionally bimodal wave attack

Prof. Tom Bruce, University of Edinburgh, Scotland

At a design stage, the admissible overtopping will be the single most important driver of the crest height of the structure and its cost. Similarly, if assessing an existing structure, e.g. for its future performance under climate change scenarios, the overtopping will be one of the most critical parameters to be able to predict.
This project will quantify the influence of directionally bimodal seas on three-dimensional wave overtopping at sloping and vertical structures.
This access project will focus on the realistic, short- crested seas and will deliver understanding and quantification of the influence of short-crestedness upon wave overtopping prediction formulae for sloping and vertical structures.

Dynamic Coastal Protection: Resilience of Dynamic
Revetments Under SLR

Dr. Christopher Edwin Blenkinsopp, University of Bath, UK

A dynamic revetment is a ridge of cobbles constructed around the wave run-up limit which is designed to mimic composite beaches which consist of a lower foreshore of sand and a backshore ridge constructed of gravel or cobbles which stabilises the upper beach and provides overtopping protection to the hinterland.  The overall aim of this project construct a prototype-scale beach and investigate the response of the beach to a rising sea level and storms with and without a dynamic revetment structure through 3 main work packages:

WP1 Determine the performance of dynamic revetments to a rising sea-level and their resilience in response to a range of high and low-energy wave conditions. Analyse the response of the sandy foreshore to SLR with and without the presence of a revetment. 

WP2 Gain fundamental information about wave transformation in the surf and swash zones, beachface morphology change and the dynamics of nearshore bars due to changing waves and water levels. This fundamental knowledge will enable an understanding of the revetment performance and beach response to SLR, potentially indicating approaches to improve revetment design and beach resilience. 

WP3 Test and improve the capabilities of parametric and process-based models in predicting wave transformation and morphology changes of the sandy beach alone and in presence of the dynamic revetment using the laboratory results. Generalise the results to prototype conditions to optimize the dynamic coastal protection design in the presence of SLR.

RODBreak - Wave run-up, overtopping and damage in rubble-mound breakwaters under oblique extreme wave conditions due to climate change scenarios

Dr. João Alfredo Ferreira dos Santos, Ass. Prof., Instituto Superior de Engenharia de Lisboa, Lisbon, Portugal

Wave breaking, run-up and overtopping and their impact in the stability of rubble mound breakwaters are not adequately characterized yet for climate change scenarios. This project will help by assessing design and maintenance strategies to increase their lifespan and resilience, reducing monetary costs for re-construction and climate change adaptation.



Leibniz University Hannover / GWK

Response of Ecologically-mediated Shallow Intertidal Shore Transitions to extreme hydrodynamic forcing (RESIST)

Dr. Iris Möller, University of Cambridge, UK

Salt marshes are increasingly valued for their role in coastal defence, as they reduce the impact of waves and erosion on shorelines and engineered coastal defences behind salt marshes. Yet the response of salt marsh margins to extreme hydrodynamic forcing is complex and currently not well understood. This project thus aims to quantify:

  1. how extreme wave-forcing affects seedling survival of different pioneer species;
  2. how (and to what extent) vegetation typically present in the salt marsh pioneer zone affects erosion processes and rates under extreme forcing;
  3. how small clifflets at the seaward margin of dense salt marsh canopies respond to high energy wave conditions;
  4. what damage is caused by drag forces in terms of marsh plant breakage under extreme conditions; and
  5. how novel artificial erosion protection / stabilisation methods may be used to protect seedlings as a restoration measure (see 1) and reduce clifflet erosion as a conservation measure (see 3).



Experimental study on wave propagation in ice and the combined action of waves and ice on structures

Dr. Hilde Benedikte Østlund, Kvaerner Concrete Solutions, Concepts and R&D, Norway

The decline of ice extent in Arctic regions observed during the recent decades leads to a significant change of weather conditions in these areas. As a result of the weather change stronger winds and gales can be expected. Recognizing that destructive storms with associated high amplitude waves will become more commonplace as global climate warming intensifies and that waves will be able to penetrate further into the pack ice because more open water is present, it is timely to adapt the current understanding of operational conditions and environmental loads on structures in Arctic waters by focusing on marginal Ice Zone (MIZ).

The proposed experimental study would help to shed light on both the manner in which waves adjust during their passage through broken ice and how a floating structure is affected by the combined action of waves and ice.

The proposed study is based on collecting experimental data from the model basin.

Three tasks are planned to be accomplished:

  1. Measurement of wave propagation in ice;
  2. Measurement of the motion behaviour of an  individual ice floe in regular waves;
  3. Measurement of the load on a floating structure due to broken ice moving in waves.



Sea Ice Dynamics: Role of Broken Ice in Multi‐scale Deformation

Prof. Peter Robert Sammonds, Institute for Risk and Disaster Reduction, University College London, UK

The experiments will both improve fundamental knowledge of sea ice mechanics and, combined with the modelling, lead to new improved models of sea ice dynamics including how the presence of broken ice between the sliding surfaces affects friction.

The results achieved in the experiments will be will be correlated with results obtained from sea ice at Svalbard during field campaigns.




Internal wave dynamics in the marginal ice zone

Dr. Magda Carr, University of St Andrews, UK

The project contributes to a better understanding of internal wave dynamics and in particular, how the internal wave dynamics is affected by changes in both ice cover and stratification, which is necessary to know how the Arctic will adapt to climate change. The experimental data will be analysed to determine the parametric relationship between internal wave dynamics, stratification and ice properties.




Investigation of bending rheology of floating saline ice and physical mechanisms of wave damping

Prof. Aleksey Marchenko, University Centre in Svalbard,
Longyearbyen, Norway

The aims are to investigate bending rheology (flow properties) and failure conditions of floating solid ice, and investigate damping of waves propagating below the solid and fractured ice.



UHULL / Total Environment Simulator

Testing a novel explanatory factor for the non‐linearity between rainfall event magnitude‐frequency and catchment erosion.

Dr. ir. Jantiene EM Baartman / Soil Physics and Land Management Group, Wageningen University

Field and numerical modelling studies emphasize non-linearity and self-organising behaviour within catchments; intense rainfall events do not necessarily produce high net erosion and low rainfall may result in high erosion. An explanation for this behaviour is a change in connectivity, resulting in a sudden pulse of sediment transport. This project will:
1) test the non-linear effect of varying sequences of rainfall event frequency and magnitude on sediment erosion and transport dynamics;
2) quantify the connectivity after each event as a novel explanatory factor for this non-linearity.



UHULL / Total Environment Simulator

Flow through emergent and submerged patches in wide shallow flow

Prof. Olivier Eiff, KIT Karlsruhe, Germany

Mean and turbulent flow will be measured using 2D and 3D PIV in and around submerged and emergent vegetation in a wide open-channel.  Two types of vegetation ‘patch’ will be compared; (i) an artificial structure constructed using thin glass sheets as leaf elements and (ii) a real leafy plant. PIV-measurements in the artificial structure will have similitude in LAI (Leaf Area Index) and porosity to the real plant. The experiments will be complemented with LES simulations to investigate drag modelling of the patch.

Smelling vortices: Animal tracking of chemical scents in turbulent, unidirectional flows

Dr. Elena Tricarico, University of Florence, Italy

This project aims to understand the propagation and reception of chemical signals by organisms through hydrodynamically complex environments. This knowledge is essential to make a step-change in our understanding of how animals navigate river environments and communicate with other organisms. The experiments consist of a series of flume experiments, where crayfish movement and activity will be tracked relative to chemical plumes.

MoDEX: Morphological diffusivity experiment - controls on morphological diffusivity for innovative beach protection schemes

Dr. Matthieu de Schipper, University of Delft, Delft, the Netherlands

Beach replenishments, where sand from offshore is disposed on or near the beach, are the principal mitigation measure in adaptive coastal maintenance during times of climate change for many locations. To apply such promising maintenance schemes it is paramount to have knowledge and a good prediction skill of morphological diffusivity and its driving processes. Project experiments focus on the three-dimensional morphological diffusivity.
