The generalized reciprocal method (GRM), one of the seismic refraction methods, provides a technique to accommodate irregular refractor. Seismic refraction software is developed using Visual Basic (VB) which is one of the user friendly programming languages. That is consistent user friendly interface and the fastest and the easiest way to create applications for Microsoft windows®. The developed software (SEISREF) aims on implementing the features of the generalized reciprocal method (GRM) and was tested using both synthetic and real data and it proved to be very good and functionalenin Refraction Selsmology (Seisref)Thesis
