FAYETTEVILLE, Ark. – An international team of physicists, led by a research group at the University of Arkansas, has discovered that heating can be used to control the curvature of ripples in freestan...
Male túngara frogs call from puddles to attract females. The production of the call incidentally creates ripples that spread across the water. Researchers at the Smithsonian Tropical Research Institut...

The discovery in 2004 by Mars exploration rover Opportunity of sedimentary rocks with centimeter-scale trough cross-bedding is one of the compelling lines of evidence for flowing water on the Martian ...
Toward Improving Prediction of Sediment Transport over Wave-Induced Ripples
Wave-Induced Ripples Analytical eddy viscosity formulation
2011/8/29
Sediment transport over wave-induced ripples is a very complex phenomenon where available models fail to provide accurate predictions. For coastal engineering applications, the 1-DV advection-diffusio...
Distribution and Steepness of Ripples on Carrier Waves
Carrier Waves Distribution Steepness
2009/2/13
The slopes of ripples and the profiles of their carrier waves were simultaneously measured in a wind-wave tank with winds of various velocities blowing over preexisting, long, regular surface waves. T...
