Flows in estuarial and coastal regions may be described by the shallow-water equations. The processes of pollution transport, sediment transport and plume dispersion are driven by the underlying hydrodynamics. Accurate resolution of these processes requires a three-dimensional formulation with turbulence modelling, which is very demanding computationally. A(More)
11. UK coasts are subject to widespread erosion in part due to the cumulative effect of human intervention on soft coastlines, and further threatened due to more rapid change due to climate change, especially sea-level rise. At the same time, Shoreline Management now requires predictions of coastal evolution up to 100 years in the future. This leads to the(More)
SUMMARY The finite-element shallow-water solver TELEMAC-2D is applied to tidal flows in a region off the coast of East Anglia, UK, as shown in Part 1, for a period of 216 hours in year 2000. Boundary conditions for surface elevation and depth-averaged velocity are provided by the UK continental shelf model CS3 of the Proudman Oceanographic Laboratory, which(More)
Tsunamis caused by landslides may result in significant destruction of the surroundings with both societal and industrial impact. The 1958 Lituya Bay landslide and tsunami is a recent and well-documented terrestrial landslide generating a tsunami with a run-up of 524 m. Although recent computational techniques have shown good performance in the estimation(More)
The large lateral hole of the Sprotte needle is claimed to aid cerebrospinal fluid efflux during the performance of spinal anaesthesia. Using theoretical calculations and practical measurement we have shown that reducing the area of the lateral hole to that of the cross sectional area of the needle does not affect the flow rate. We suggest this modified(More)
—The high computational cost of SPH remains problematic in dealing with wave propagation, especially when the domains considered are large. In order to overcome this difficulty, we propose to couple 2-D SPH with a 1-D Finite Difference Boussinesq-type model. The latter deals with wave propagations for most of the spatial domain, whereas SPH computations(More)
