Unsteady Flow Computation Using Junctions Group Method in River Network

This paper discussed the juntions group method initially put forth by Li Yitian in datail,and advanced a new method,which can be applied in wide practices and is worth being recommended.The advantage of the new method is that the coding works of junctions can be handed in each sub-area individually,and the water level equations of junctions group can be obtained directly by using the original relations among junctions suitable to the common gradation method.
