The CSUB package defines some data sets that apply to all active cells in the model and others that only apply to individual interbed cells. In this example, the following properties in the CSUB package will apply to all cells.
Layer |
Initial_Coarse_Porosity (cg_theta) |
Initial_Elastic_Recompression_Index (cg_ske_cr) |
Moist_Specific_Gravity (sgm) |
Saturated_Specific_Gravity (sgs) |
Layer 1 |
0.32 |
0.005 |
1.77 |
2.06 |
Layer 2 |
0.32 |
0.005 |
1.77 |
2.05 |
Layer 3 |
0.45054945 |
0.01 |
1.6 |
1.94 |
Layer 4 |
0.32 |
0.005 |
1.77 |
2.06 |
In this case, we will use default formulas in the Data Sets dialog box to set the values of the data sets. The following formulas can be used. For a reminder how to do this, see CSUB Example: Aquifer Properties. (The porosity in layer 3 is derived from the void ratio (VOID) of 0.82 originally specified in Leake and Galloway (2007). Porosity = VOID/(1+VOID).
