| Abstract: | Based on the reciprocal curvilinear approach of discharge modulus, with the application of the coaxial diagram and the numerical superposition rule, a graphic calculation applicable to rivers in the mountainous areas is put forward. The method is comparatively direct with a high accuracy and an easiness to check the errors. It can accelerate the operational speed when a series of flow profiles are required. |
