沟道粗糙地是一个巨大的侵蚀复合体，由侵蚀到玄武岩基岩和哥伦比亚高原上覆沉积物中的高度过拟合的直立沟道组成。根据一个简单的层次分类描述了这些河道中的侵蚀和沉积床形。灾难性的洪水通过岩石和沉积物的侵蚀以及沉积（沙洲）产生了宏观形态（尺度受河道宽度控制）。中型（规模由河道深度控制）也是侵蚀和沉积的。
The channeled scabland is a great anastomosing complex of highly overfit stand channels eroded into the basalt bedrock and overlying sediments of the Columbia Plateau. Both the erosional and depositional bed forms in these channels are described according to a simple hierarchical classification. The catastrophic flood flows produced macroforms (scale controlled by channel width) through the erosion of rock and sediment and by deposition (bars). Mesoforms (scale controlled by channel depth) are also erosional and depositional.
