Bowers cross plot - Velocity vs Effective Stress

The Velocity vs Effective Stress cross plot is used to verify that unloading is present in the subsurface and to check and review the output of the various calculations in the Bower's Method workflow. The cross plot can be opened via the Bowers Eq Depth or the Bowers Unloading forms in the 1D Model > Pore Pressure sub-strip. To aid in determining and refining the input parameters for the Bowers Unloading pore pressure, the following data can be displayed and analyzed in the cross plot:

• Velocity vs Effective Stress, theoretical velocity as calculated in the Bowers Eq Depth form versus the effective stress calculated in the Effective Overburden form
• Vmax, as specified in the V0 and Vmax form
• Pressure measurements (calibration points) above and below TVDSS max
• Theoretical velocity, as calculated in the Bowers Eq Depth form
• Bower's Unloading Curve
• Velocity (below TVD max)

The cross plot is designed to work together with the Bowers Eq Depth and Bowers Unloading forms. As you perform the calculations in each form you can return to this cross plot to observe the results. Depending on the results, you can then return to the respective form and adjust and refine the parameters of your calculations.
