Test Cases CVMH Flags
The user can specify whether a geotechnical layer, based on Ely Vs30 technique is added to the top 300M of the cvm-h model, by editing a flag in the ucvm.conf file. The user can also include a 1D background model to extend CVM-H beyond its model boundary by editing a flag in the ucvm.conf file.
# The entries below are manually updated by the user, as needed. # # CVM-H model flags. The model defaults are: # No 1D background model # No GTL added # cvmh_param=USE_1D_BKG,False cvmh_param=USE_GTL,False #
We expect that Vs values in the top 300m will be lower for sites when the USE_GTL flag is set to true.
cvmh_param=USE_1D_BKG,False cvmh_param=USE_GTL,True
Plot the Vs depth profiles of 5 locations with the last one being outside of the CVM-H boundary,

A cross plot through Southern part of CVM-H,
./plot_cross_section.py -b 33.25,-119 -u 36,-112 -h 1000 -v 10 -d vs -c cvmh -a d -s 0.0 -e 100 00 -o cvmh_gtl.png

With GTL,
./bin/ucvm_query -f ./conf/ucvm.conf -m cvmh -c gd < ./tests/inputs/test_latlons_socal_pts.txt > ucvm_cvmh_depth_usegtl_false_results.txt
Result:
This shows the the USE_GTL flag return different material properties in the top 500m. However, the columns showing combined results (from model and GTL) are identical. This suggests that the combined properties columns change only when an external GTL is returned from the UCVM. CVM-H internal GTL does not appear as a "combined" material properties, but rather as native model properties.
The user can specify a CVM-H configuration flag that enables or disables use of a 1D background model. The default CVM-H flag is not to use a 1D background model. We expect ucvm to return material properties for regions outside of the CVM-H region when the 1D background model is true.
Rerunning the earlier cross plot with 1D enabled,
# cvmh_param=USE_1D_BKG,True cvmh_param=USE_GTL,False #
With 1D but without GTL,
With 1D but also with GTL,
We called ucvm_query this way:
./bin/ucvm_query -f ./conf/ucvm.conf -m cvmh -c gd < ./tests/inputs/test_latlons_socal_pts.txt > ucvm_cvmh_depth_1dtrue_results.txt
Following are the result of toggling the USE_1D_BKG flag (without GTL),
Show that the CVM-H model with added GTL (not the ucvm.conf USE_GTL flag) impacts the combined data column.
When UCVM adds an external GTL to the CVM-H model, the combined_data columns return the results.
Show that the CVM-H model with added GTL (not the ucvm.conf USE_GTL flag) impacts the combined data column.
When UCVM adds an external GTL to the CVM-H model, the combined_data columns return the results.

Query CVM-H with USE_GTL flag. Query it again adding external GTL. Show final results are identical.
