1Sedimentation horizon 1 is named "General" and defined by a single facet.

2The facet geometry is horizontal and has an initial elevation of 25mm; i.e. less than the height of the original sediment (30mm high).

3The horizon is defined as moving with a reference vertical displacement of 20mm and time curve 1000.

4Time curve 1000 defines that the sedimentation horizon moves at constant rate between time t=1.0 and t=6.0.

 Stratigraphy_unit_name    "Sand2"

 Sediment_horizon_name   "General"      

 Material_name            "Sand_1"

 Duration                      0.8

1Three Sedimentation_data keywords are defined at time t=3.0, t=4.0 and t=5.0.

2Each data structure defines:

(a)  The name of the new stratigraphy unit

(b)  The sedimentation horizon to be used (always "General")

(c)  The material properties to be assigned to the new unit (always "Sand_1")

(d)  The duration of the gravity initiation for the new layer (always 0.8)
