Domain decomposition and model integration
Weiming Wu · 2007
Many problems in river engineering exhibit geometric irregularities andmultiple length and time scales in flow velocity andmass concentration. To handle these characteristics effectively, the computational domain is often decomposed into subdomains that may be represented by meshes with different grid densities and topologies, and treated by models with different dimensions and complexities. The multiblock algorithm, coupling of 1-D, 2-D and 3-D models, and integration of channel and watershed models are introduced in this chapter.
