The flow in each sub basin is calculated and then added together to get the runoff concentration of the main river.

在模型建立的过程中， 将流域划分为几个子流域， 先对每个子流域中的产流进行计算， 通过河道进行汇流。

This paper focuses on mini basin characteristics of runoff concentration based on the simulation and computation of 13 mini basins.

该文通过13个特小流域的汇流模拟计算，研究了特小流域的汇流特征。

Runoff concentration can be generalized as transposition and attenuation of flood waves, which are the basis of most basin runoff concentration models.

流域汇流可以概化为洪水波的平移和坦化作用，平移和坦化模拟是大多数概念性汇流模型的核心。
