(Luleå University, Sweden) and Prof. P. Overduin (Alfred

Wegner Institute, Germany).

During her Postdoc, Guegan plans to continue and extend

the scope of her fieldwork to include jet erosion tests,

which she believes are highly applicable to Arctic coasts.

Guegan intends to focus on erosion of cohesive sediment

under turbulent flow, which can provide valuable full-scale

data for modelling of Arctic coastal erosion. For example,

measuring field erodibility in terms of critical shear stress

and erodibility coefficient provides important inputs to

hydrodynamic models and can be used to validate geotech-

nical THM models.

Dr. Anatoly Sinitsyn has been the co-supervisor for Emilie

Guegan in 2015 and together they have submitted two

journal papers of which one has already been accepted.

During 2015 Sinitsyn visited Vestpynten field site several

times and downloaded data from thermistor strings and

piezometers. In collaboration with PhD candidate David

Wrangborg (working in WP1 in 2015), Sinitsyn scanned the

coastal bluff at Vestpynten with a laser scanner. Two data

reports describing the overall data collection and laser

scanning in Vestpynten were prepared by Sinitsyn and

Guegan in 2015.

wave-structure interaction, fl oating body dynamics, slosh-

ing or sediment transport. The sediment transport is

coupled with the high-resolution wave and fl ow field. In the

first part of the PhD study, the numerical model has been

validated for local scour laboratory cases under current

and wave conditions. His dissemination contribution to WP6

is of great importance, adding three conference papers and

one journal paper to the total number of papers for this WP

in 2015 (see list of publications).

Measurements and Modelling of Arctic

Coastal Erosion

Postdoc Emilie Guegan dedicated 2015 to completing her

doctoral thesis and writing and submitting journal papers

in collaboration with researchers at NTNU, UNIS, SINTEF

and Moscow State University (MSU).

Guegan had two journal papers accepted with minor

revision in 2015 and we expect these papers to be published

in 2016. The highlight of 2015 for Guegan was definitely the

public defence of her doctoral thesis on December 10th,

2015. The defence was successful and concluded with

positive comments from her opponents, Prof. S.Knutson
