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 ... -
An integrated measurement and modeling methodology for estuarine water quality management
Hartnett, Michael; Nash, Stephen (Elsevier BV, 2015-01-01) -
Assessment of environmental compliance of waterbodies through integration of monitoring and modelling
McGovern, Joseph Vincent (2016-09-30)Design of water quality monitoring networks in estuarine and coastal waters is hampered by a lack of a clear methodology. Monitoring networks are designed on an ad-hoc basis supported by experts in the area. Guidance on ... -
Assessment of Tc-99 monitoring within the western Irish Sea using a numerical model
Olbert, Agnieszka Indiana; Hartnett, Michael; Dabrowski, Tomasz (Elsevier ScienceDirect, 2010-05-26)Water circulation patterns and associated material transport within a highly dynamic system such as the Irish Sea are complex phenomena. Although Tc-99 monitoring programme undertaken by the Radiological Protection Institute ... -
Comparative study on assimilating remote sensing high frequency radar surface currents at an atlantic marine renewable energy test site
Ren, Lei; Hartnett, Michael (MDPI AG, 2017-12-19)A variety of data assimilation approaches have been applied to enhance modelling capability and accuracy using observations from different sources. The algorithms have varying degrees of complexity of implementation, and ... -
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, ... -
The development of a high-resolution nested bridge hydraulic model
Yu, Haofeng (NUI Galway, 2023-11-23)Traditionally, hydraulic modelling of bridges has been undertaken using one dimensional models like HEC-RAS. One-dimensional models simplify river channels using several cross sections along a river curve and strongly ... -
Development of a nested coastal circulation model: boundary error reduction
Nash, Stephen; Hartnett, Michael (Elsevier, 2014-03)Numerical models have a valuable role to play in the sustainable management of coastal waters but accurate simulation of land/sea interactions, particularly in areas of complex coastlines, requires the use of high spatial ... -
Development of a Two-Dimensional Estuarine Hydrodynamic Model in Cylindrical Co-ordinates
Boblea, Luminita-Elena (2014-02-03)Development of a novel two-dimensional estuarine hydrodynamic model in cylindrical co-ordinates is presented herein. The full non-linear Navier-Stokes equations are written in cylindrical co-ordinates with the advantage ... -
Development of an efficient dynamically nested model for tidal hydraulics and solute transport
Nash, Stephen (2010-06)Numerical modelling of coastal zones typically requires a high spatial resolution to accurately simulate land-sea interactions, particularly in areas of complex coastlines. As a result, the computational cost of coastal ... -
Development of computationally efficient nested hydrodynamic models
O'Brien, Noreen (2014-04-25)Hydrodynamic numerical modelling of coastal zones typically requires a high level of horizontal spatial resolution to improve the realism of its solution, particularly in areas of complex bathymetry. These high resolution ... -
Development of efficient data assimilation methods for solute transport problems
Zayats, Mykhaylo (NUI Galway, 2018-09-18)The solution of marine contaminant transport problems is a significant research topic in civil engineering. Typically, the problem is represented as a partial differential equation described by the non-stationary, ... -
