Université de Sherbrooke and the University of Ottawa are seeking 2 
postdoctoral researchers in Coastal Engineering 

1. Experimental and numerical experiments to determine the design parameters of 
short groins used for coastal beach protection
2. Experimental and numerical experiments to investigate end-wall scour effects 
around coastal protection structures 

Context: In Eastern Province of Quebec (Canada), one-third of the population 
and nearly 60% of national roads are located less than 500 m from the coast. A 
study on the vulnerability of road infrastructure in Eastern Quebec to coastal 
erosion and submersion in the context of climate change indicates that 34 km of 
roads are imminently exposed to erosion, while 123 km will be impacted by 2100 
due to the effects of climate change.  To protect its infrastructure from 
coastal erosion, the Quebec’s Ministry of Transports (MTQ) has constructed rock 
revetments and vertical walls. These rigid structures protect the coastline 
directly behind them – however, they influence sedimentary transport on the 
seaward side. The result can be a complete loss of the natural beach and an 
accelerated deterioration of adjacent areas through end-wall scour effects, 
which can necessitate further intervention. Alternative methods that can be 
used in combination with protective structures include the construction of 
short groins, which are structures built perpendicular to the coast and whose 
purpose is to capture sand and gravel transported by coastal currents to help 
maintain an extended beach capable of protecting the coast by absorbing wave 
energy.

Research Objectives: 
The overall objective of Project 1 is to provide rules for the design of short 
groins in a climate change context with a focus on impact on coastal processes 
(morphohydrodynamic changes). Specific objectives include: (1) literature 
review on the effect of groins on coastal morphodynamics with and without the 
presence of protective structures; (2) development and validation of a 3D 
numerical model (using OpenFOAM) with experimental data available in the 
literature on sediment transport around short groins; (3) experimental (wave 
basin) and numerical study on the effects of short groins on coastal 
morphodynamics under different wave conditions with and without protective 
structures (vertical walls and rock revetments); (4) developing new design 
recommendations for short groins that minimize maintenance and the negative 
effects of changes in coastline morphodynamics for specific MTQ works.

The overall objective of Project 2 is to develop a numerical model and conduct 
laboratory experiments to predict end-wall scour effects and test passive 
control solutions. Specific objectives include: (1) literature review on in-
situ, laboratory measurements and numerical modeling of coastal morphodynamics 
in the vicinity of coastal protection structures (i.e., vertical wall, 
revetments) with an emphasis on end-wall scour effects; (2) development and 
validation of a 3D numerical model using experimental data available in the 
literature on sediment transport; (3) experimental (wave basin) and numerical 
study of end-wall scour effects for vertical walls and rock revetments for 
various wave conditions with added scenarios for climate change effects (4) 
test of passive control techniques via the use of rockfill or submerged walls 
to mitigate end-wall scour effects and (5) development of design 
recommendations for specific MTQ works.

Methodology: 
A 150 m² basin equipped with a wave maker, a beach and a dissipative structure 
will be built in the Civil Engineering Department at the Université de 
Sherbrooke. A variety of intruments (wave gauges, ADVs (acoustic Doppler 
velocimeter) and ADCPs (acoustic Doppler current profiler) will be used to 
characterise the hydrodynamic conditions while and sediment transport will be 
measured via ADCP bottom tracking and by SfM (structure from motion).

A 3D numerical model will be developed using OpenFOAM (using the OlaFOAM 
package already available to the team). The model will have to be further 
developed for sediment transport (eg., inclusion of the model proposed by Ouda 
and Toorman, 2019). The final model will be integrated into a workflow written 
under Python to automate the generation of geometry, mesh, calculations and 
post-processing. The calculations will be performed using the supercomputers of 
the Compute Canada network.

Selection Criteria:
· A PhD qualification in a relevant subject: fluid mechanics, CFD, physical 
oceanography or related fields. 
· Extensive competence and experience in CFD modeling, especially using 
OpenFOAM.
· Experience in laboratory experimentation and advanced measurement techniques 
such as ADV and PIV is an asset.
· Proven track record of peer-reviewed scientific publications.
· Supervisory skills are an asset.
  Opened to Canadian citizens, Permanent Residents, as well as international 
applicants.

Institution: The 2 postdocs will work in close collaboration to help design the 
new experimental facility, run experiments and improve the CFD model. Both 
projects are financially supported for three years by the Québec Ministry of 
Transport.The workplace is at the Faculty of Engineering at the Université de 
Sherbrooke, in close collaboration with Prof. Ioan Nistor from the Department 
of Civil Engineering at the University of Ottawa and the Ministry of 
Transports. Laboratory experiments will be conducted in the Civil Engineering 
Hydraulics Laboratory while the CFD studies will be affiliated with Mechanical 
Engineering.. A salary of 45,000 CAD/year (before tax) and excellent working 
conditions are offered (Canadian national medical insurance program, 
opportunities to attend conferences, professional development, etc). Starting 
date: March or April, 2020. Interested candidates are encouraged to contact by 
email: Prof Jay Lacey (Jay.Lacey@USherbrooke.ca), Prof. Sébastien Poncet 
(Sebastien.Poncet@USherbrooke.ca), and Prof. Ioan Nistor (inistor@uottawa.ca). 
Send detailed CV, 2 recommendation letters and copies of 3 relevant journal 
publications. Please mention your interest (Project 1 or/and 2) when applying 
and note that incomplete application will not be considered. The duration of 
initial contract is 1 year, extendable up to 3 years, contingent to 
satisfactory performance appraisal.

The this work we consider the full-field simulation of the sonic boom 
propagation using an accurate and adaptive numerical method. The sonic boom 
consists in a strong acoustic disturbance resulting from shock waves 
generated by aircrafts in supersonic flight. The shock waves coalesce into a 
single wave with a characteristic N shape that propagates in the farfield 
along very long distances. The associated pressure variations cause strong 
noise pollution on the ground and prevent supersonic flight over land. The 
analysis of this phenomenon is therefore of strong interest for the design 
of “low-boom” aircraft configurations that would reduce the intensity of the 
boom on the ground to allow supersonic flight over land and hence reduce 
travel time. 

Due the low intensity of the acoustic waves to be propagated over very long 
distances (several kilometers), the simulation of this phenomenon requires 
the use of highly accurate numerical methods. For this purpose we propose to 
employ a high-order discontinuous Galerkin method (DGM).  The DGM is a 
compact finite element method which solves for a piecewise polynomial 
approximate solution. This method results in very low dispersion and 
dissipation errors which are essential features for wave problems. 
Additionally, it allows the efficient adaptation of the spatial resolution 
by locally modifying the approximation order and the cell size while 
employing unstructured meshes. Both aspects constitute key ingredients for 
the efficiency of the simulations. 

The DGM can present however numerical instabilities when applied to the 
compressible Euler equations, mainly due to the introduction of truncation 
errors in the treatment of non-linear terms. These errors can seriously 
affect the quality and robustness of the numerical simulations and, in some 
cases, lead to non-physical solutions. 

One possible stabilization technique consists in the decomposition of the 
convective flux operator employing the so called summation by parts property 
which preserves in discrete form the integration by parts theorem used for 
the employed variational formulation. In this work we propose to extend this 
methodology to the non-linear small perturbation formulation of the Euler 
and compressible Navier-Stokes equations, commonly employed for acoustic 
propagation simulations.

Over the course of this study we will analyse the theoretical stability, the 
dispersion and dissipation properties of the numerical scheme and their 
impact on the propagation of acoustic waves. Slope limiters on non-
structured meshes will also be analysed in order to stabilize the numerical 
simulations in presence of discountinuities. The developed methodology will 
be implemented in the CFD solver AGHORA, developed at ONERA, and will be 
analysed by performing numerical simulations. The influence of non-
linearities and of the physical viscosity on the wave structure will also be 
analysed.

The advertised post is for a Research Associate to work with Dr Anastasia Kisil 
within the Waves in Complex Continua Group in the Department of Mathematics at 
Manchester. The appointee will develop a new theoretical framework for 
understanding the wave scattering effects of edges in acoustic metamaterials. 
There has been extensive research into how waves propagate within a 
metamaterial (periodic materials) but there are substantially fewer results 
about the way waves interact with the edges of the metamaterials. These results 
are important, have many applications in noise reduction and naturally build 
upon the mathematical methods used for canonical scattering problems. There is 
also a possibility to explore the aeroacoustic uses of these metamaterials. 
There is substantial flexibility within the project so it can be adapted to 
suit the strengths of the appointee. This post is funded via Kisil’s Royal 
Society Dorothy Hodgkin Research and Dame Kathleen Ollerenshaw Fellowships.

The Waves in Complex Continua Group has broad research interests in 
metamaterials, wave propagation and scattering in fluids and solids with 
applications including aero and hydroacoustics, elastodynamics, and industrial 
and biological composite materials.  Other activities in physical applied 
mathematics within the Department of Mathematics cover areas such as high 
Reynolds number and experimental fluid dynamics, fluid structure interactions, 
solid mechanics, granular materials and inverse problems.

Applicants should have, or be working towards, a PhD level qualification in 
applied mathematics or a related discipline. Experience of research in the 
field of mathematical analysis of wave scattering is essential, and some 
knowledge of numerical implementation would be highly advantageous. No prior 
knowledge of analysis of metamaterial is required. The appointee must have 
knowledge of skills commensurate with the intended analysis and should be 
capable of working under their own initiative. The appointed individual will 
work as part of a larger team so excellent communication and organisational 
skills are required.
