在现场和实验室数据的基础上，研究了天然砾石铺砌通道的水力学特性，这些数据涵盖了流量范围从1 cfs到10万cfs，床层材料尺寸范围从0.5 in。到18英寸。天然砾石路面似乎与低床载运输条件密切相关。将牵引力与床层物料粒度的关系方程、指数流动公式和状态型宽度-流量关系结合起来，形成了一套通道设计规则。说明了一些可能的应用。简要介绍了砾石路面取样的方法。
The hydraulics of naturally gravel-paved channels are examined on the basis of field and laboratory data covering a discharge range from 1 cfs to 100,000 cfs and a bed-material-size range from 0.5 in. to 18 in. Natural gravel pavements appear to be closely associated with conditions of low bed-load transport. An equation relating tractive force to bed material size, an exponential flow formula, and a regime-type width-discharge relationship are combined to form a set of channel design rules. Some possible applications are stated. Methods for sampling gravel pavements are also mentioned briefly.
