Behaviour of solutions,iscussed below in section 4.3). This implies that you can think of solutions as combinations of waves. The viscosity terms do have an influence: they will act as a damping mechanism. However, they are often not very large and you can generally assume that the wave properties are not essentially alte作者: Affiliation 時間: 2025-3-22 07:39
Boundary conditions,tions is closely related to the behaviour of characteristics if the system is hyperbolic. The SWE are hyperbolic if you do not take lateral friction into account. You can find the relevant theory in Courant & Hilbert (1962). It says first of all that the region of interest should be enclosed by a bo作者: atopic-rhinitis 時間: 2025-3-22 11:27
Time integration methods,all unknowns and . is a “mass matrix”; it is nontrivial in finite-element methods but is unity in most other cases. The number of equations equals the number of grid-point values and may be very large. Several standard numerical methods exist to integrate such systems of differential equations. They作者: explicit 時間: 2025-3-22 16:22
Effects of time discretization on wave propagation,using the finite-difference analogue of (7.1):.(on the right-hand side, . is an exponent). The eigenvector v. of the matrix ... in (8.1) is the same as in the semi-discretized continuous-time case. The error is therefore characterized by comparing ρ. to exp(-.) with . and . is the wave frequency for作者: 哀悼 時間: 2025-3-22 20:44 作者: chiropractor 時間: 2025-3-22 21:52 作者: Scintillations 時間: 2025-3-23 04:57 作者: AXIS 時間: 2025-3-23 08:10
Numerical treatment of boundary conditions, grid points around the central point. If applied at a boundary, you would need values from grid points located outside the region, which is impossible. Various approaches are possible to get additional equations on the boundary:作者: 忘川河 時間: 2025-3-23 13:47 作者: GROG 時間: 2025-3-23 16:55 作者: BINGE 時間: 2025-3-23 18:32 作者: Cervical-Spine 時間: 2025-3-24 01:01
Three-dimensional shallow-water flow,where the 2-d model is not good enough but where the shallow-water approximation can still be made. In such cases, you will have to solve the 3-d SWE (or, what amounts to the same thing, boundary-layer equations). Some of the reasons may be the following.作者: OUTRE 時間: 2025-3-24 03:28 作者: 遭受 時間: 2025-3-24 07:57 作者: FLOAT 時間: 2025-3-24 13:48 作者: Proclaim 時間: 2025-3-24 15:00

Some properties,The SWE have the same appearance as the Euler equations for compressible flow in aerodynamics. It is important to be aware of this similarity, because it opens the vast body of experience with the numerical solution of the Euler equations for application to the SWE.作者: 失望未來 時間: 2025-3-25 15:17
Discretization in space,In this chapter, the spatial discretization of the shallow-water equations is discussed. The most common approach is that of finite differences, in which the region of interest is covered by a rectangular grid with grid sizes Δx, Δ. and the spatial derivatives are approximatedby finite differences.作者: observatory 時間: 2025-3-25 19:18
Effects of space discretization on wave propagation,The solution of the discretized equations derived in ch. 6 will not be the same as the continuous one, but hopefully close to it. The question of numerical accuracy can be approached in a number of ways: analysis of the truncation error, experimental numerical convergence analysis and wave-propagation analysis for the linearized equations.作者: 含水層 時間: 2025-3-25 22:50 作者: 商品 時間: 2025-3-26 00:49 作者: V洗浴 時間: 2025-3-26 04:24
