    • Adaptive Mesh Multi-Scale Modelling of Tidal Hydraulics and Material Transport 

      Nash, Stephen; Hartnett, Michael (2011)
      Multi-scale modelling for structured meshes is achieved by nesting high resolution grids within lower resolution grids. By specifying high resolutions in areas of interest only, computational cost can be reduced. Adaptive ...

    • An adaptive mesh solute transport model 

      Nash, Stephen; Hartnett, Michael (2009)
      An adaptive mesh solute transport model is presented. The adaptive mesh scheme is implemented in a one-way multiply nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport). The ...

    • Cyclonic circulation in the western Irish Sea in future climate 

      Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (International Association for Hydro-Environment Engineering and Research, 2011-07-01)
      The Irish Sea (IS) is a semi-enclosed body of water on the European Continental Shelf and the Western Irish Sea Gyre (WISG) is a characteristic phenomenon of the Sea. The gyre due to its significant effects on the circulation, ...

    • Interactions, mechanisms and impact of future coastal urban flooding. A case study of Cork city 

      Kirkpatrick, Jennifer Isabel Munro; Nash, Stephen; Hartnett, Michael; Comer, Joanne; Olbert, Agnieszka Indiana (Hydrology Ireland, 2020-11-17)
      In coastal floodplains, high river flows and high coastal water levels can result in extensive flooding. Mechanisms of flooding play a crucial role in flood characteristics with distinctive differences in flood wave ...

    • Mechanisms of flooding in Cork City 

      Olbert, Agnieszka Indiana; Comer, Joanne; Nash, Stephen; Hartnett, Michael (International Association of Hydrological Sciences, 2015-11-17)
      Flooding is one of the most frequent and devastating natural disasters. Many urban developments are located in estuaries where river flow and sea water merge. Cork City situated in the River Lee estuary frequently subject ...

    • A nested hydrodynamic model incorporating flooding and drying 

      Nash, Stephen; Hartnett, Michael (2009)
      A one-way nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport) is introduced. The nested model allows flooding and drying of intertidal areas, a process often present in areas ...

    • Nutrient dynamics in Cork Harbour 

      Nash, Stephen; Hartnett, Michael (2005)
      Estuaries are commonly characterised by high productivity due to frequent if not continuous inputs of nutrients from domestic and industrial discharge effluents and from freshwater and marine sources. These forms of nutrient ...

    • Parameterization of turbulence models using 3DVAR data 

      Olbert, Agnieszka Indiana; Nash, Stephen; Hartnett, Michael (City University of New York, 2014-01-08)
      In this research the 3DVAR data assimilation scheme is implemented in the numerical model DIVAST in order to optimize the performance of the numerical model by selecting an appropriate turbulence scheme and tuning its ...

    • A Performance Assessment Protocol for Structured Mesh Multi-Scale Models 

      Nash, Stephen; Hartnett, Michael (2011)
      Nesting techniques are used to develop multi-scale models giving higher resolution and thus greater accuracy in nested domains. The assessment of model accuracy is therefore important for the successful implementation of ...

    • Turbulence modelling using 3DVAR data assimilation in laboratory conditions 

      Olbert, Agnieszka Indiana; Nash, Stephen; Hartnett, Michael (2013)
      The viability of turbulence parameter estimation in a numerical model using 3DVAR data assimilation technique is explored in this research. Water currents measured in a physical model are assimilated into the numerical ...
