Abstract
This paper describes a Finite-Volume Methode (FVM) to caculate coastal flows, in complex geometry. Non-orthogonal boundary-fitted grid with Node-Center variables arrangements are used here. Cartesian unit-width discharge components are chosen as dependant variables. The model is validated by some test cases. 1 Introduction The 2-D Shallow Water Equation (SWE) in a generalized coordinates sys- tem are usually solved by the Finite Elements Method (FEM) or the Finite Differences Method (FDM). The first method is heavy and expensive, al- though it presents a large flexibility for mesh generation. In the second, the use of staggered grid prevents the c/teg%er6oW sp/z^m^ of free-surface elevation (FSE), while a non-staggered grid seems to be easy to code. The m
