Lesson No. 22: Numerical Solution for a Refraction Profile Over a Single Dipping Interface
Published:January 01, 1959
As a consequence of the discussion and exercises of the preceding lesson, we are now in a position to solve a numerical problem, based on corrected field data, of a two-layer refraction profile in which the interface is dipping along the line of the profile.
The solution should be studied not only for its intrinsic value as a step toward learning the interpretation techniques for this and for more complicated refraction problems, but also because this type of solution is often used to study low-velocity layers for the purpose of making corrections for other types of seismic data (particularly reflection travel-times). It should be apparent that the disposition of the interface between the low-velocity layer and the beds beneath can often be detailed by short reversed refraction profiles of the type we are discussing here.

“An elementary text and problem book containing 44 lessons in seismology arranged for selection or combination to cover the normal 36-week course, or for condensation into an 18-week course. The lessons begin without assuming more than secondary school mathematics. An elementary knowledge of calculus is desirable, though not required, for the last half of the book.”
