Surface waves can carry important information about near surface. For instance if there are some oil pipes beneath the earth and there is a major leakage and a polluted area is made, surface waves can investigate the anomaly and with its interpretation the anomaly can be modeled. Therefore, it is a common practice to apply corrections to the reflection seismic data (known as static corrections) to eliminate the influence of weathering layers or investigate its properties. These corrections are made using estimates of the velocity models near the Earth's surface. Surface-wave methods (SWM) are a seismic approach, which can be used to achieve a velocity model.
