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
