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 numerical tests which underline the importance of the angle dependency .
