使用沿印度南部一条被切割的短暂通道的通道几何形状和衬底阻力的测量来检查衬底对通道几何形状的影响。研究表明，随着衬底阻力的增大，河道变窄变深，河壁和河床地形起伏，局部侵蚀以凹坑和纵向沟槽的形式增加，河床坡度变得更加陡峭和变化。
Surveys of channel geometry and substrate resistance along an incised ephemeral channel in southern India were used to examine the influence of substrate on channel geometry. The surveys indicate that as substrate resistance increases, the channel grows narrower and deeper, with undulating wall and bed topography, more localized erosion in the form of potholes and longitudinal grooves, and a steeper and more variable bed gradient.
