WebUsing the nonlinear sand wave model, the evolution towards equilibrium is investigated. Wind waves reduce the equilibrium height and enhance the migration speed caused by wind-driven currents. Wind-driven currents result in asymmetrical sand wave shapes and migration in the direction of their steepest slope. Web2 de set. de 2015 · Study of sand wave migration over five years as observed in two windfarm development areas, and the implications for building on moving substrates in the North Sea Authors: Ken Games Retired...
A physically-modified spectral model for prediction of sand wave migration
