Characteristic-based split (CBS) algorithm finite element modelling for shallow waters in the Venice lagoon

摘要

In this paper, the characteristic-based split (CBS) algorithm is presented to solve water motion problem due to tides in the Venice lagoon. The basic equations are the well-known vertically integrated shallow-water equations expressed in terms of total water depth and horizontal velocities. The approximation of any additional scalar variables, such as temperature, concentration or pollutant dispersion from the appropriate advection-diffusion governing equations is also outlined. Numerical results illustrate the performance of the proposed algorithm on both advection-diffusion and shallow-water problems. Copyright (c) 2006 John Wiley & Sons, Ltd.
