Patterns of Water Runoff

The effects of the runoff of precipitated water constitute a major part of the physical weathering process of the Earth.

降水径流的影响构成了地球物理风化过程的主要部分。

This is a false-color image of an arid area in southeastern Jordan. It was acquired in May 2001 by the ASTER instrument onboard NASA's Terra satellite. It shows the effect of meandering, rain-swollen wadis on the landscape of the area. The Arabic word "wadi" means a gulley or streambed that typically remains dry except after drenching, seasonal rains. This image was featured on the cover of Science, February 4, 2005. The image and description are from NASA and USGS. This and other images from the Terra program can be found at the USGS website. http://www.usgs.gov .

这是一张假彩色图像，显示了约旦东南部干旱地区的地貌。该图像于2001年5月由NASA的Terra卫星上的ASTER仪器获取。图像展示了蜿蜒的、被雨水填充的wadi对当地地貌的影响。阿拉伯语中的“wadi”指的是一种通常在季节性降雨后才会被淹没的沟壑或溪流。这张图像于2005年2月4日被刊登在《科学》杂志的封面上。图像和描述来自NASA和USGS。其他Terra计划的图像也可以在USGS网站上找到。http://www.usgs.gov.

This is a selection of about one fifth of the area of the image above it. It's general similarity to the image of the larger area, and the fact that small sections of it resemble the whole, is reminiscent of a fractal pattern.

这是一幅上方图像面积的约五分之一。它与较大面积图像的一般相似性，以及其小部分与整体相似的特性，让人联想到分形图案。
