        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 ...

      • 1‐D Dam‐Break Flood‐Wave Propagation on Dry Bed 

        Constantine V. Bellos; John G. Sakkas (American Society of Civil Engineers, 1987)
        The complete hydrodynamic equations of the shallow‐water theory in one dimension are employed to compute the flood wave resulting from the total and instantaneous collapse of a dam in a broad rectangular channel. The ...

      • 1‐D Open‐Channel Flow Simulation Using TVD‐McCormack Scheme 

        P. García‐Navarro; F. Alcrudo; J. M. Savirón (American Society of Civil Engineers, 1992)
        The addition of a dissipation step to the widely used McCormack numerical scheme is proposed for solving one‐dimensional open‐channel flow equations. The extra step is devised according to the theory of total variation ...
