Mild slope equation
Webwave propagation can be simulated with the mild-slope equation. For most applications, then, one resorts to approximate methods of solving the mild-slope equation. These approximate methods consist of: (i) the parabolic equation method 1~-~3, (ii) the RCPWAVE model 1~ and (iii) the EVP model ~s. http://sms.aquaveo.com/ApplOcRes1991.pdf

Web6 mrt. 2024 · The shallow-water equations (SWE) are a set of hyperbolic partial differential equations (or parabolic if viscous shear is considered) that describe the flow below a pressure surface in a fluid (sometimes, but not necessarily, a free surface ). [1] The shallow-water equations in unidirectional form are also called Saint-Venant equations, after ... WebIn this paper we report our recent p rogress on second-order diract ion of bodies on slowly varying depth, for monochromatic incident waves. The mild-slope equation is rst extended to second order in wave steepness, and the method of solutions is then described. Sample results are then discussed.
