| 摘 要： | 径流流速不仅是坡面径流的重要水动力学特性，而且是计算其他水力特性及侵蚀产沙的重要参数，本文目的在于研究坡面细沟流和细沟间薄层水流流速沿坡面的变化过程，比较细沟和细沟间径流流速的差别。实验选取1m、2．5m、4m、5．5m、7m、8．5m和10m共7个坡长的小区（均为5。），装填粉壤土，采用历时2h、总雨量121mm的变...

| Abstract: | Flow velocity is not only an important hydraulic property of overland flow,but also an indispensable index to calculate other hydraulic parameters.The purpose of this paper is to investigate the spatial distribution of rill and interrill flow velocity along the hillslope.Simulated rainfall and 7 plots(5 degrees steepness) with the lengths of 1,2.5,4,5.5,7,8.5 and 10 m,repectively,were employed.The tested soil was a silty loam,sampled from Yanqing County,Beijing.For each slope length,the experiment consisted... |
