As there have been many widely used watershed hydrological models, it now becomes possible to select a number of different hydrological models in parallel running for rainfall-runoff simulation.

由于目前已有很多比较成熟的流域水文模型，因此我们可以选用几个流域水文模型进行并行运算，来同时模拟流域降雨—径流关系。

Rainfall simulation experiment was performed to evaluate nitrogen losses from farmland and show the effect of fertilizer application on nitrogen concentration and losses of runoff.

在室内降雨模拟试验条件下，研究暴雨径流中农田氮素养分流失及施肥处理的影响。 结果表明，农田暴雨径流氮养分的流失量与累积径流量成正相关；
