| 摘 要： | 在水平入渗方法的基础上,提出了一种不需测定饱和导水率,仅利用一维垂直入渗试验即可确定Brooks-Co-rey模型参数的新方法.利用封丘县两种质地土壤的入渗资料,对所提出的方法进行了检验.结果表明,只要入渗历时足够长,基质势和重力势作用相当,垂直入渗方法确定的土壤水力参数与水平吸渗方法的预测结果相近;利用预测的参数,数...

| Abstract: | A new method is proposed for estimating soil hydraulic parameters in the Brooks-Corey model.The method uses only one-dimensional vertical infiltration experiments,thus,measurement of saturated hydraulic conductivity is not required.The method is tested in two soil textures in Fengqiu County.The result shows that the Brooks-Corey soil parameters estimated by the new method are quite comparable to those of using the horizontal absorption method when the gravitational potential is balanced by the matric potent... |
