This paper deals with the numerical solution of the shallow water equations in channels with irregular geometry but with a locally rectangular cross section. This type of channel leads to the presence of source terms involving the gradient of the depth and the breadth of the channel. Extensions of t

A novel scheme has been developed for data reconstruction within a Godunovtype method for solving the shallow-water equations with source terms. In contrast to conventional data reconstruction methods based on conservative variables, the water surface level is chosen as the basis for data reconstruc

## Abstract The present work addresses the numerical prediction of shallow water flows with the application of the HLLE approximate Riemann solver. This Riemann solver has several desirable properties, such as, ease of implementation, satisfaction of entropy conditions, high shock resolution and po
