Data lines to define drainage-only seepage:

First line:

1. Surface name.

2. Seepage flow type label QD.

3. Drainage-only seepage coefficient value,

. (Units of F

−1

L

3

T

−1

.)

Repeat this data line as often as necessary to define drainage-only seepage for various surfaces.

Data lines to define nonuniform seepage:

First line:

1. Surface name.

2. Seepage flow type label QNU.

3. Optional reference pore pressure value. If given, this value is passed into 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 necessary to define nonuniform seepage for various surfaces.
