Applied Hydrogeology - Fetter - 4t Edition - Chapter 12 - Solutions

12.1 This is a two-layer, seismic-refraction problem. A seismic line was run with the following first-arrival- time results:...

(A) Find V₁.(B) Find V₂.(C) Find i_c.(D) Find Z.

12.2 This is a three-layer seismic problem. Table 12.2 contains first-arrival times that were measured in both the forward and reverse directions. Find the seismic velocities for each layer in each direction; then average them and use the average values to find Z₁ and Z₂ as well as the critical angle between layer 1 and layer 2.
