streambed

Within 30 minutes, I was marching up a dry streambed, above the trees, on a ridge matted with magenta shrubs and dotted by boulders..差不多30分钟的时候，我走在一个干枯的河床，上面长着树，在凸起的地方遍布着红色的灌木丛和星星点点的石头。

The profile of the new streambed shall be designed and constructed to maintain the flow at the retained stream sections in dry season..新河床水平的设计及建造，须确保被保留河段的水流，在旱季得以维持。

Once the aquifer disconnect from the stream, the inverted saturated zone of the rectangular streambed show a hemicycle, and that of rectangular streambed show a vertical rhombus..当河流与地下水脱节后，矩形河床的悬挂饱水带呈半圆形，三角形河床的悬挂饱水带呈直立菱形。
