Hydrodynamic impact of a tidal barrage in the Severn Estuary, UK

Xia, Junqiang; Falconer, Roger A.; Lin, Binliang - In: Renewable Energy 35 (2010) 7, pp. 1455-1468

The Severn Estuary has a spring tidal range approaching 14m, which is among the highest tides in the world. Various proposals have been made regarding the construction of a tidal barrage across the estuary to enable tidal energy to be generated. The aim of the current study is to investigate the...

Schwarz methods for discrete elliptic and parabolic problems with an application to nuclear waste repository modelling

Blaheta, R.; Kohut, R.; Neytcheva, M.; Starý, J. - In: Mathematics and Computers in Simulation (MATCOM) 76 (2007) 1, pp. 18-27

The paper is devoted to the numerical solution of both elliptic and parabolic problems by overlapping Schwarz methods. It demonstrates that while the two-level Schwarz method is necessary for the efficient solution of discrete elliptic problems, the one-level Schwarz method can be sufficiently...
