Specifies the effective density of the soil on a per unit volume basis. This option displays only when you select American Lifelines Alliance in the Soil Model Type list.

The effective density of the soil may differ from the dry density if the soil is wet, and thus less buoyant. The effective density of the soil is less than the dry density of the soil. If the water table may engulf the pipe even for a short time, then it is probably appropriate to enter a wet effective density. If the soil is expected to remain dry, then enter the dry soil density. The following tables list some typical soil densities:
