论文摘要
降雨量的岩石溶解通常会产生流向平行的通道，但这些自然模式的发生尚待理解。在这里，我们报告了在最初扁平材料表面的流向溶解模式的实验室中的出现，该材料倾斜并受到较薄的径流水流。几乎平行的凹槽宽约1毫米，并沿主斜率自发形成。它们的宽度和深度随时间不断增加，直到它们的冠峰出现并引导流动为止。我们的观察结果可能构成在田间观察到的模式的早期阶段。
The dissolution of rocks by rainfall commonly generates streamwise parallel channels, yet the occurrence of these natural patterns remains to be understood. Here, we report the emergence in the laboratory of a streamwise dissolution pattern at the surface of an initially flat soluble material, inclined and subjected to a thin runoff water flow. Nearly parallel grooves about 1 mm wide and directed along the main slope spontaneously form. Their width and depth increase continuously with time until their crests emerge and channelize the flow. Our observations may constitute the early stage of the patterns observed in the field.
