title = "Seismic refraction interpretation using finite difference method",
abstract = "Correct interpretations of seismic refraction profiles are contingent upon accurate processing, especially in problematic sites where hidden layers may be present. It is found that the Generalized Reciprocal Method (GRM), which is used to solve hidden layer problems, does not give accurate results in some areas without additional modification to the processing flow. To improve the final GRMderived velocity-depth (V-D) model, the Finite Difference (FD) method is employed to calculate the first arrival's direct and refracted times for any velocity medium. This newly-developed FD technique is then used to improve the initial GRM-derived V-D model. Three synthetic seismic data sets are used to validate this technique, each processed by GRM-only and FD modified GRM. In each case, the FD modifications are found to provide more accurate results in comparison to those from GRM-only processing flows.",
