Shuitu Baochi Xuebao, 2008 在分析积水入渗条件下短历时Philip入渗公式特点基础上,建立了基于短历时Philip积水入渗公式的降雨产流模型。模型显示地表积水时刻与雨强平方成反比。利用降雨强度为0.082 cm/min、坡度为15°情况下实测累计降雨产流量推求了模型参数吸渗率,并利用获得的S分别计算了雨强为0.214 cm/min、坡度为5°,雨强为0.133 cm/min、坡度为5°和雨强为0.133 cm/min、坡度为15°情况下累积径流量,相对于实测累积径流过程,计算相对误差都在10%内,可以满足精度要求 ...

Shuitu Baochi Xuebao, 2006 通过人工模拟降雨方法对四川盆地紫色土坡耕地产流特征进行研究,得到以下结论:(1)在大雨强情况下,起始产流时间受坡度影响不明显;在小雨强时,起始产流时间随坡度的增加而缩短。小雨强下坡度对起始产流时间的影响可用幂函数表示,相关性显著。(2)裸地径流强度明显大于农地,且变化剧烈;(3)大雨强下坡度对径流系数的影响显著,并存在临界坡度:裸地介于10~°15,°农地约为20°。

Shuitu Baochi Xuebao[目的] 为研究降雨、汇流和坡度对浅沟侵蚀的影响,实施精确的水土保持措施。[方法] 通过室内模拟降雨和汇流试验,设计2个降雨强度(50,100 mm/h)和2个坡度(3°,7°),并在4种降雨强度和坡度组合下设置5个依次增加的汇流强度(15,30,45,60,75 L/min),分析降雨、汇流和坡度及其交互作用对浅沟坡面侵蚀的影响,明确浅沟侵蚀对坡面侵蚀的贡献。[结果] (1)坡度和汇流强度对浅沟坡面侵蚀的影响均大于降雨强度。当降雨强度由50 mm/h增加到100 mm/h时,3°和7 ...
