OCTAVE fqKVMBscan.m - Kelvin-Voigt (KV) to Hydraulic Conductivity (Kd) Plot
fqKVMBscan prompts for:
User enters
hydrauic conductivity (Kd) and porosity values for a curve
(GUI Entry Box)
X-prompt to use mouse to place porosity and Kd label on plot
X-prompt to continue and add another plot, or to quit.
Plots can be saved using the GUI interface in the plot
menu.
Basic Seismic Utilities (BSU) program run in Octave or Matlab. Within an octave session, type fqKVMBscan and a GUI pops up as shown above. The mapping between the KVMB and KV constitutive representations depends on pore diameter, porosity, frequency, and viscosity of fluid. Setting the frequency and porosity (n) selects a curve. Examine the code for other assumptions. Reference: Michaels (2006) "Relating Damping to Soil Permeability" Vol. 6, No. 3, International Journal of Geomechanics, ASCE p. 158-165.
GUI entry box as given above.
