Junior Researcher (Doctoral Candidate)

Ref:2023_13

Salary: £36,386-£43,626 (in accordance with the EU Marie Skłodowska-Curie-Actions financial guidelines for this scheme)

Duration: 36-month fixed-term contract

HR Wallingford have an exciting opening for a Junior Researcher (Doctoral Candidate) to join the SEDIMARE Doctoral Network consortium. The successful candidate will be based in the Coasts and Oceans Group in Wallingford and enrolled for a fee-free PhD at the UK Open University researching a multi-model approach to scour in dynamic areas. The position includes secondment opportunities to the University of Nottingham, UK and the University of Patras, Greece. The successful candidate will work on the development of an accurate integrated scour dynamics tool.

The SEDIMARE Doctoral Network consortium will provide a training-through-research program to 12 Doctoral Award/PhD Candidates across Europe and the UK in complex sediment transport processes involving sand-mud mixtures, mixed-size sands, granular-fluid mixtures; coupling between hydrodynamics (waves, storm surges, and tides), sediment transport, morphological changes, and engineering solutions to issues related to erosion/sedimentation with emphasis on sustainability and resilience. The research methods include effective process-based engineering modelling, advanced numerical simulations, and innovative experiments.

This project aims to combine different model approaches (Computational Fluid Dynamics (CFD), St-Venant and empirical) to provide an accurate integrated scour dynamics tool, that can be applied in morphologically active locations and includes the interactions between scour around coastal structures and the wider morphodynamics.

Taking the strength of the 3 approaches, the turbulence modelling of the CFD, the sand transport predictions of the St Venant models and the grounding in reality of the empirical models, cutting-edge improvements can be achieved on the individual approaches.

You will be responsible for conducting research on sediment transport and scour processes, and the coupling between hydrodynamics and sediment transport to predict large scale morphological changes. You will develop and implement effective process-based engineering models and run advanced numerical simulations to better understand these complex processes. You will collaborate with other members of the SEDIMARE Doctoral Network . As part of your role, you will attend and present at national and international conferences and workshops and write and submit scientific articles for publication in international peer-reviewed journals.

Requirements

• Hold a primary degree or masters in civil / mechanical / maritime engineering, physical oceanography, physics, applied mathematics, or a related discipline.
• Meet the Marie Skłodowska-Curie Early-Stage Researcher eligibility criteria. Further information can be found at http://ec.europa.eu/research/participants/data/ref/h2020/wp/2016_2017/main/h2020-wp1617-msca_en.pdf.
• At the time of appointment, have less than four years full-time equivalent research experience and must not have already obtained a PhD.
• Have not resided in the UK (recruiting host country) for more than 12 months in the three years immediately before the appointment.
• Have a strong interest in sediment transport processes, hydrodynamics, and morphodynamics.
• Strong scientific computing skills are required. Experience with OpenFoam and/or openTELEMAC preferred. Be able to work independently and collaboratively.
• Have excellent oral and written communication skills.
• Be able to travel to other institutions within the SEDIMARE Doctoral Network consortium.

Please note: the language of MSCA is English and candidates must have evidenced proficiency in English to meet HR Wallingford’s requirements.

Benefits

• Attractive salary in accordance with MSCA regulations for Doctoral Candidates, including living allowance, mobility allowance, and family allowance (if applicable).
• Enrolment for a fee-free PhD at the UK Open University.
• Secondment opportunities to the University of Nottingham, UK and the University of Patras, Greece
• Opportunities to collaborate with international experts in the field of sediment transport and morphodynamics in marine and coastal waters with engineering solutions.
• Opportunities to attend and present at national and international conferences and workshops.
• Funded PhD for the period of employment, with options for further financial support.

Dear researchers,

Professor Erik A. Toorman has a postdoc position available (12 to max. 18 months) to work on treatment of tidal flats in TELEMAC (The position can be filled in immediately).

This is in the framework of our Eulerian plastic litter transport model development for a Flemish project (www.Pluxin.be) and an EU H2020 project (www.Labplas.eu), where we develop a floating litter module (in analogy to bedload) for which beaching and shore pickup of litter needs to be modelled as well (in combination with the drying-wetting algorithm).

If you know a postdoc with good TELEMAC experience who might be interested, let her/him get in touch with me.

Best regards

Erik A. Toorman
Professor in theoretical and computational fluid and sediment mechanics, KU Leuven

Post-doc position on Hydrodynamic and sediment transport model of the Mahury estuary (French Guiana)

Details

Published on Tuesday, 03 October 2017 10:15

The 300 km coastline of French Guiana is one of the most dynamic coastlines due to mud banks migration. Along this shoreline, several rivers flow to the Atlantic Ocean and interact with these mud banks. Most of the population, which is expected to double in the next decades, lives along rivers or near the coastline. This growth combined with industrial developments and global warming increase the vulnerability against flooding and beach erosion. A project between CEREMA and BRGM has been funded to analyze (1) the interactions between rivers and the coastal mud bank migration and (2) their impact on risks management.

The studied site is the Mahury estuary where is located the main Port of French Guiana. Since 2012, a mud bank is migrating along the mouth which induces severe sediment settling and continuously dredging. The main city "Cayenne" is also located beside the mouth. Sand beaches of the city are fed by sediment fluxes from the Mahury and offshore fluxes. The presence of mud bank modifies the dynamics: wave attenuation by mud, coarser particles trapped by mud and modification of stratification pattern. The fluxes modification may induce more sediment deficit and increase the risk of sea flooding.

Within this framework, it is proposed to build a 3D hydrodynamic and sediment transport model of the Mahury estuary. The numerical models will be based on the open source TELEMAC-MASCARET modeling system (www.opentelemac.org). The ability of the numerical model to predict the maximum turbidity and its seasonal variation will be investigated. Once validated, the model should provide information related to the influence of the mud bank and modification of the main forcing. The numerical model will benefit from several in situ data (PhD Orseau 2016) and from remote sensing data (PhD Abascal Zorrilla in progress).

We are looking for a candidate having a PhD in fluid mechanics, hydraulics, geosciences or coastal oceanography and strong expertise related to sedimentology (cohesive and non-cohesive), geomorphology, fluid mechanics, hydraulics, wave modeling and numerical methods. Knowledge of French language is not mandatory.

About the host research laboratory:

The welcoming laboratory is the joint research unit (between Université de Technologie de Compiègne and the CEREMA Water Sea and Rivers) located in Compiègne in France (40 min by train from Paris).
