Parameterization of turbulence models using 3DVAR data
(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 ...
Turbulence modelling using 3DVAR data assimilation in laboratory conditions
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 ...
Cyclonic circulation in the western Irish Sea in future climate
(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, ...
Mechanisms of flooding in Cork City
(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 ...
Adaptive Mesh Multi-Scale Modelling of Tidal Hydraulics and Material Transport
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 ...
A Performance Assessment Protocol for Structured Mesh Multi-Scale Models
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 ...
