Abstract
Combined boundary element and weighted finite difference method for water flow M. an oh', H. Okuzonol, N. ~akarnura' & T. ~ u r o k i ~ I Department of Civil Engineering, Kyushu Sangyo University, Japan 2 Department of Civil Engineering, Fukuoka University, Japan Abstract In an earlier study, we had identified the boundary element and weighted finite difference methods used to analyze the saltwater wedge diffusion in groundwater (Kanoh et al. [I]). In this paper, we extend the methodology and propose a combined boundary element and weighted finite difference method for water flow. By using the weighted finite difference method (WFDM), the nonlinear flow, which includes convective diffusion and shallow water flow problems, can be accurately calculated. On the other hand, the boundary element method (BEM) is an excellent way to handle the moving boundary technique and intricate boundary conditions, such as an absorbing boundary of waves or a piston wave- maker motion boundary. These two methods w
