- Title:
- Study on Slope Farmland Runoff Model in Blackland Based on 1-D Saint-Venant Equation
- Keywords:
- slope farmland; simulated rainfall method; blackland; runoff; model
- 分类号:

- 摘要:
- 在野外模拟降雨的基础上，建立基于一维圣维南运动方程的黑土区坡耕地径流模型。分析结果表明，该模型应用于小面积径流计算时精度很高，但在进行野外坡面径流量的预测时，不能忽略控制面积的大幅扩大对模型预测精度的影响。
- Abstract:
- According to the observation data and outcomes of artificial rainfall, based on the overland flow formulas established slope farmland runoff model. The results show that the precision of the model is well, but the influence to the precision of the model in the prediction of field runoff can’t be ignored.
