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 improve physical understanding which is crucial to predict changes to nutrient fluxes, pollutant retention/flushing, the growth of harmful algae, and the transport of phytoplankton and ichthyoplankton.
The proposal aligns with current EU strategy on the adaption to climate change (EU, 2013) by aiming to address specific gaps in knowledge associated with exchange flow dynamics within coastal zones and regional seas.

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.

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.

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

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.

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).

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.

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.
