Mastersthesis Reference Etude d'impact des changements hydrodynamiques induits par une ferme d'aquaculture de moules offshore
About 30 years ago, researchers of RBINS developed COHERENS (coupled hydrodynamical-ecological model for regional and shelf seas), a three-dimensional hydrodynamic model designed for a wide range of applications in coastal and shelf seas, estuaries, lakes and reservoirs. The main goal of this internship is to quantify the hydrographic changes (especially marine currents) induced by an offshore mussel aquaculture farm similar to the industrial project "Wesdiep Sea Farm", using the COHERENS model. The mussel aquaculture technique used in this project is known to disturb currents and turbulence in the water column. The goal of this internship is to implement the parameterisation of the impacts of the mussel droppers in the COHERENS hydrodynamic model as well as the addition of a new source term for turbulent kinetic energy production. Then, a sensitivity study will be carried out using the implementation made in a test case of a simplified mussel aquaculture farm. Note that in parallel to this report, a more complete report was produced for RBINS within the framework of this internship and the student has already been offered a contract of employment.

Unpublished Reference Quantification of hydrodynamic changes induced by an offshore mussel aquaculture farm (Part 1)
The goal of this end-of-studies internship proposed by the Royal Belgian Institute of Natural Sciences (RBINS) is the quantification of hydrodynamic changes (especially sea currents) induced by an offshore aquaculture farm similar to that of the industrial project “Westdiep Sea Farm”. The mussel aquaculture technique used in this project is known to disturb currents by, among other things, increasing the velocity of currents under the farm and significantly increasing the turbulence developing in the wake of the rigs. However, according to the knowledge of the RBINS, no study quantifies these disturbances. From an environmental point of view, an open question is whether or not these changes can modify the erosion/sedimentation pattern around the farm, leading, for example, to a risk of destabilization of the neighbouring sandbanks. First, the objective of this internship is to implement the parameterization of droppers impacts in the COHERENS hydrodynamic model. For this, a literature study will be carried out. Then, a sensitivity study will be conducted in order to use the implementation in a test case of a similar and simplified mussel farm. If time permits, the final objective would be to apply these different tests and simulations on the realistic case of the "Westdiep Sea Farm".

Unpublished Reference Quantification of hydrodynamic changes induced by an offshore mussel aquaculture farm (SYMAPA)
The goal of this numerical study is the quantification of hydrodynamic changes (especially sea currents) induced by an offshore aquaculture farm similar to that of the industrial project “Westdiep Sea Farm”. To do that, a parameterization of the impact of longlines and droppers on hydrodynamics has been included in the 3D COHERENS hydrodynamic model and the impact of several configurations of the aquaculture farm on currents and bottom shear stress has been estimated in a simplified test case. The mussel aquaculture technique of longlines used in this project is known to disturb currents by, among other things, increasing the velocity of currents under the farm and significantly increasing the turbulence developing in the wake of the rigs. From an environmental point of view, an open question is whether or not these changes can modify the erosion/sedimentation pattern around the farm, leading, for example, to a risk of destabilization of the neighbouring sandbanks. As part of the SYMAPA (Synergy between Mariculture & Passive Fisheries) project, the goal is to link current variations in and around the farm to the amount of food available for mussels attached to droppers. At the seabed, a link between hydrodynamic processes and modification of the sedimentation scheme may be considered following this report. This preliminary study can help lead to the final goal of determining the scope of the impact that the aquaculture farm may have on the ecosystems in the farm and on the benthos. Three major effects will be studied for three different farm designs: the impact on surface currents, the sinking of currents under the farm and the impact on bottom shear stress.
