Specification of soil subsidences with predefined shape (Input Table)
Data description/conditions:
Identifier: (toggleable)
Identification name of data reference point
Required
SUBZMAX:
Maximum value of subsidence in z-direction
≠ 0. / Required
(For downward subsidence this value must be negative.)
UNCF:
Uncertainty factor for subsidence (1)
≥ 1.
[Default: 1.5]
LENGTH:
Length over which subsidence varies from zero to maximum value by half of sine wave cycle / length of block subsidence
> 0.
SINESHAPE:
Type of sine wave
Prescribed names: Double / Left / Right / Block
(Double: Half of sine wave length at both sides of X-P
Left: Half of sine wave length before X-P, zero after X-P
Right: Half of sine wave length after X-P, zero before X-P
In all cases the maximum value of twice the sine amplitude occurs at X-P.
Block: Block shaped subsidence with jump from zero to SUBZMAX at X-P, constant value between X-P and X-P + LENGTH, and a jump back to zero at X-P + LENGTH.)

SUBZMAX is always multiplied by UNCF.
