+31(0)88335 8314Robin.Morelissen@deltares.nl LinkedIn profile
Mr Morelissen is a senior researcher/consultant in the field of coastal hydrodynamics, intakes and outfalls and dredging-related topics. By carrying out many projects all over the world, he has developed a wide experience and in-depth knowledge in the fields of tidal and industrial outfall hydrodynamics, density driven flows, flushing analyses and (metocean) data analysis. In particular, Mr Morelissen is experienced in coupled near and far field modelling techniques (plume modelling) used in dredge plume studies and recirculation studies for industrial intakes and outfalls. Mr Morelissen has a key role in developments around the coupling of near and far field models and advanced modelling techniques in engineering practice.
Mr Morelissen had a key role as a project manager in (multi-disciplinary) projects concerning studies for new reclamations, flushing studies, dredging (sediment dispersion) impact studies and recirculation studies. Mr Morelissen further coordinates the intake/outfall recirculation and coastal hydrodynamics team within Deltares to align the research and services in this field with the demands of the market.

Thermal Modelling and Hydraulic Computations Sohar Cooling Water Outfall Extension
Mr Morelissen was project manager and hydrodynamic modelling advisor for an outfall plume dispersion and recirculation study for the extension of a large cooling water outfall in Oman. This study considered both the hydraulic aspects of the onshore cooling water channels and the offshore dispersion of the outfall plume. In this study, advanced modelling techniques such as a Scenario-Based Adaptive Modelling approach were used to assess the outfall plume dispersion and recirculation against several operational, environmental and social criteria.
Expert Opinion Sohar Cooling Water Discharge Temperature Criterion
Mr Morelissen was project manager and one of the lead researchers in the development of a new, ecologically relevant and site-specific temperature criterion for a large cooling water outfall in Oman. This updated criterion is designed to protect better the ecology in the vicinity of the outfall than with the present criterion in place and at the same time created more room for the outfall design.
Recirculation modelling San Gabriel power plant
Mr Morelissen was project manager and hydrodynamic modelling advisor in an efficient and detailed recirculation modelling study for a power plant extension in the Philippines. In this project, advanced modelling techniques such as a Scenario-Based Adaptive Modelling approach and the Distributed Entrainment Sinks Approach were successfully applied.
Baseline and Modelling studies for the Mirfa Power and Desalination Plant
Abu Dhabi, 2013
Mr Morelissen was project manager in a detailed marine impact study for a combined power plant and desalination outfall design, in which near and far field hydrodynamics, water quality and ecological effects were assessed. In this project, engineers from the Client (ADWEA/NEWRC) were trained on the job at Deltares (Mirfa IWPP);
Development of a Dynamically Coupled Thermal Recirculation Model
Mr Morelissen was project manager and lead researcher in a comprehensive thermal outfall recirculation study for large power plants in South-Korea. In this project, the dynamically coupled near field – far field modelling system (Delft3D-CORMIX) was further developed and successfully applied and validated in a complex environment. This state-of-the-art modelling technique has shown to produce more accurate results than traditional modelling techniques, which were of great value to this project. The models and modelling technique + training were part of the project deliverables. Furthermore, this advanced modelling approach has been adopted and approved by the Korean Institute of Nuclear Safety.
Sediment Dispersion Modelling, Lough Foyle (NI)
North Ireland, 2008
Mr Morelissen was project manager and had a key role in a maintenance dredging impact study in Lough Foyle, Northern Ireland. In this study, the impacts of a changed dredging regime were assessed and consisted of the development of a calibrated three-dimensional hydrodynamic model and short and long term sediment dispersion modelling, including coupled near and far field modelling;
Jumeirah Garden City and Canals
Mr Morelissen was project manager and had a key role in a comprehensive study on the Jumeira Gardens islands scheme. The study consisted of flow (flushing), wave and beach assessments. The results of these assessments were used to improve the Masterplan layout;

Abu Dhabi, 2007
Khalifa port, dredge plume modelling. Mr Morelissen was project manager of this project and had key roles in the sediment plume assessment;
Maldives Hulhumale Port and Resort
Design support assessment (hydrodynamics, waves, beach design, water quality and nautics) for a planned port and resort. Mr Morelissen was project manager of this project and had key roles in the hydrodynamic modelling;
Assessment of hydrodynamic flow conditions for construction planning of Stonecutters Bridge, Hong Kong
Hong Kong, 2006
Assessment of hydrodynamic flow conditions for construction planning of Stonecutters Bridge, Hong Kong. This study included the set up of a detailed 3D hydrodynamic model and the development of a digital tidal atlas, capable of predicting flow fields during the construction phase. Mr Morelissen was project manager of this project and had key roles in the development of the model and tidal atlas;
