Data lines to define drainage-only seepage:
First line:
1. Surface name.
2. Seepage flow type label QD .
3. Drainage-only seepage coefficient value,
.(UnitsofF

.)
Repeat this data line as often as necessary to define drainage-only seepage for var ious surfaces.
Data lines to define nonuniform seepage:
First line:
1. Surface name.
2. Seepage flow type label QNU.
3. Optional reference pore pressurevalue. If given, this value is passedinto user subroutine FLOW
in the variable used to define the sink pore pressure.
4. Optional reference seepage coefficient. If given, this value is passed into user subroutine FLOW
in the variable used to define the seepage coefficient.
The reference pore pressure value,
, and reference seepage coefficient, , are defined in user
subroutine FLOW for nonuniform flow.
Repeat this data line as often as necessar y to define nonuniform seep age for various surfaces.
