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 ...

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 ...

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 ...

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 ...

The use of digital resources in higher education has risen significantly over the last ten years and will continue to do so for the foreseeable future. The challenge for educational instructors is in determining how to ...

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 ...

Tidal stream turbines provide a technically viable means of generating electricity from a sustainable resource; however, economic viability will require the deployment of multiple devices in array formations in a manner ...

The primary objective of this paper was to test the sensitivity of numerical models to bathymetry datasets. Bathymetric datasets used were from; 1) Admiralty Charts and 2) LiDAR & Multi- Beam Echo Sounder surveys. The ...

Service reservoirs provide the dual function of balancing supply with demand and providing adequate pressure in the water supply network by maintaining sufficient pressure head. In a potable water service reservoir, the ...

Vortex drop shaft structures have played a critical role in hydraulic engineering; from one of their first applications in hydroelectric energy dissipation in the 1940s, to numerous contemporary installations throughout modern ...
