Abstract: The flow on widening steep slope channels is mainly observed in the river with improve or maintain these rivers, many horizontal planes and longitudinal profiles must be fundamental function of the river shapes, and the development of the numerical analysis, which can be easily handled, is desired. complicated shapes such as mountain streams and nature-oriented river works. In order to examined considering landscape and water amenity. The that the flood flows safely should also be kept in mind, even when we apply a new approach for river planning. Therefore it is necessary to analyze the flow with complicatedRecently the MacCormack scheme has been applied to the analysis of the two-dimensional flow in which sub-critical flow intermingles with super-critical flow, and there are reports that the calculated results are good without the stability of the calculation. In this paper, experiments on the flow with hydraulic jump and the bed variation on widening results, the horizontal two-dimensionally calculation method by using the MacCormack scheme was tried. The flow and the bed variation on widening steep slope channels could be simulated comparatively well by the two-dimensional MacCormack schme. steep slope channels vicinity were conducted. In order to simulate the experimental
