Data lines to deﬁne drainage-only seepage:

First line:

1. Surface nam e.

2. Seepage ﬂow type label QD.

3. Drainage-only seepage coefﬁcient value,

.(UnitsofF

−1

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

Data lines to deﬁne nonuniform s eepage:

First line:

1. Surface nam e.

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 seep age for various surfaces.
