Hydraulic conductivity with thickness (Water Overlay)
| Icon | Attribute | Unit | Range | Description | Default value |
|---|---|---|---|---|---|
 |
HYDRAULIC_CONDUCTIVITY_WITH_THICKNESS | boolean | When selected, the Terrain value HYDRAULIC_CONDUCTIVITY_WITH_THICKNESS_MD is used for horizontal groundwater flow calculations, otherwise HYDRAULIC_CONDUCTIVITY_MD is used. | 0 |
The consideration on whether to use conductivity, or conductivity with thickness, depends on the information known about the soil.
Notes
- A value means HYDRAULIC_CONDUCTIVITY_MD will be used for horizontal groundwater flow calculations.
- A value means HYDRAULIC_CONDUCTIVITY_WITH_THICKNESS_MD will be used for horizontal groundwater flow calculations.
- Whatever the value of HYDRAULIC_CONDUCTIVITY_WITH_THICKNESS, the hydraulic conductivity can still be overridden by an Aquifer Area with its own value for AQUIFER_KD.
