Abstract. Surface waves are widely used to model shear-wave velocity of the subsurface. Surface wave tomography (SWT) has recently gained popularity for near-surface studies. Some researchers have used straight-ray SWT in which it is assumed that surface waves propagate along the straight line between receiver pairs. Alternatively, curved-ray SWT can be employed by computing the exact paths between the receiver pairs. SWT is a well-established method in seismology and has been employed in numerous seismological studies. However, it is important to make a comparison between these two SWT approaches for near-surface applications since the amount of information and the level of complexity in near-surface are different from seismological studies. We apply straight-ray and curved-ray SWT to four near-surface examples and compare the results in terms of the quality of the final model and the computational cost.

Short summary
Near-surface characterization is of great importance. Surface wave tomography (SWT) is a powerful tool to model the subsurface. In this work, we compare straight-ray and curved-ray SWT at near-surface scale. We apply both approaches on four datasets and compare the results in terms of the quality of the final model and the computational cost. We show that in case of high data coverage, straight-ray SWT can produce similar results as curved-ray SWT, but with less computational cost.
