Abstract: In this study, an improved two-dimensional (2D) model is proposed for simulating shallow water flows over complex bathymetry through their subgrid modeling. The proposed model delineates the detailed unevenness in the ...

Abstract: This paper presents a new method, the water stage prediction-correction (WSPC) method, based on the theory of characteristics to couple numerical models in the boundary-connected way for shallow-water flows. From the WSPC ...

Abstract: This paper details the development of a method for subcritical flow modeling in channel networks by using the implicit finite-difference method. The method treats backwater effects at the junction points on the basis of ...
