Roll waves emerge as uniform water flow destabilizes on steep slopes, equations show

When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, they play an important role in hydraulic engineerin This story matters for Science & Discovery readers tracking certification.
