In this paper, by analyzing the measured data of a large number of rivers, the paper analyzes the resistance composition in the two-dimensional flow calculation of river and deduces the empirical formula suitable for the distribution of resistance along the river in a planar two-dimensional water flow numerical model and applies it to the Fall River part of Colorado, The calculation of the two-dimensional flow field in the river section is in good agreement with the measured results, which overcomes the shortcomings that the two-dimensional flow velocity is not obvious.
