Angle dependence in coupling conditions for shallow water equations at canal junctions

05/01/2021 ∙ by Maya Briani, et al. ∙ 0

In this paper we propose a numerical Riemann problem solver at the junction of one dimensional shallow-water canal networks. The junction conditions take into account the angles with which the channels intersect and include the possibility of canals with different sections. The solver is illustrated with several numerical tests which underline the importance of the angle dependence to obtain reliable solutions.
