The Effect of Horizontal Shear on Extracting Water Currents From Surface Wave Data
Stefan Weichert, Benjamin K. Smeltzer, Simen Å. Ellingsen
The dispersive motion of surface waves is now routinely used to remotely measure the currents close beneath the surface of oceans and other natural flows. The current manifests as…
Biases from spectral leakage in remote sensing of near-surface currents
Stefan Weichert, Benjamin K. Smeltzer, Simen Å. Ellingsen
Remotely measuring subsurface water currents from imagery of the wave field has become a much-used technique. We study the biases and errors in such measurements due to spectral le…
An improved method for determining near-surface currents from wave dispersion measurements
Benjamin K. Smeltzer, Eirik Æsøy, Anna Ådnøy +1
A new inversion method for determining near-surface shear currents from a measured wave spectrum is introduced. The method is straightforward to implement and starts from the exist…
Waves from an oscillating point source with a free surface in the presence of a shear current
Simen Å. Ellingsen, Peder A. Tyvand
We investigate analytically the linearized water wave radiation problem for an oscillating submerged point source in an inviscid shear flow with a free surface. A constant depth is…
Oscillating line source in a shear flow with a free surface: critical layer-like contributions
Simen Å. Ellingsen, Peder A. Tyvand
The linearized water-wave radiation problem for an oscillating submerged line source in an inviscid shear flow with a free surface is investigated analytically at finite, constant…
Ship waves in the presence of uniform vorticity
Simen Å. Ellingsen
Lord Kelvin's result that waves behind a ship lie within a half-angle 19 deg 28' is perhaps the most famous and striking result in the field of surface waves. We solve the linear s…
