DATA SET 13. RAINFALL/EVAPORATION-SEEPAGE-RIVER (VARIABLE) BOUNDARY CONDITIONS

Eight groups of records are required for this data set if and only if NVES > 0. The first group is used to specify the rainfall/evaporation profile, the second group is used to read in the global nodal numbers of all NVNP rainfall/evaporation-seepage nodes, the third group is used to assign the type of rainfall/evaporation profile to each of the NVNP rainfall/evaporation-seepage sides, the fourth group is used to specify the NVES rainfall/evaporation-seepage boundary element sides, the fifth group is the river water surface profiles, the sixth group is the river water surface profile assignment, the seventh group is used to read-in the ponding depth for each of the NVNP nodes, the eighth group is used to read-in the allowed minimum pressure for each of the NVNP nodes, and .

(a) Rainfall/Potential Evaporation Profiles: There are NRPR records in this subset. The number of lines in each record depends on NRDP. The I-th (I = 1, 2, ..., NRPR) record, in FREE FORMAT, contains the following variables.

1. TRF(1,I) = Time of the first data point in the I-th profile, (T).

2. RF(1,I) = Rainfall/evaporation rate of the first data point in the I-th profile, (L/T).

3. TRF(2,I) = Time of the second data point in the I-th profile, (T).

4. RF(2,I) = Rainfall/evaporation rate of the second data point in the I-th profile, (L/T).

Up to NRDP data points.

(b) Global Node Number of all Variable Boundary (VB) nodes. At most, NVNP records are needed for this subset, each for a NVNP variable boundary node. However, if the VB nodes occur in patterns, they can be automatically generated. The I-th (I = 1, 2, ..., ) record, in FREE FORMAT, contains the following variables:

1. NI = Compressed VB node number of the first node in the sequence.

2. NSEQ = NSEQ nodes will be generated automatically.

3. NIAD = Increment of NI for each of the NSEQ nodes.

4. NODE = Global node number of node NI,

5. NODEAD = Increment of NODE for each of the NSEQ nodes.

NOTE: A line with 5 0's is used to signal the end of this data set.

(c) Rainfall/evaporation profile type assigned to each of all NVES sides. At most NVES records are needed. However, automatic generation can be made. Note that this pattern must be repeated NDF times to cover all pore regions. The I-th (I = 1, 2, ..., ) record, in FREE FORMAT, contains the following variables.

1. MI = Compressed VB element side of the first side in the sequence.

2. NSEQ = NSEQ sides will be generated automatically.

3. MIAD = Increment of NI for each of the NSEQ sides.

4. MITYP = Type of rainfall/evaporation profiles assigned to side MI.

5. MTYPAD = Increment of MITYP for each of the NSEQ sides.

NOTE: A line with 5 0's is used to signal the end of this data set.

(d) Specification of Rainfall/evaporation-seepage Sides: Normally, NVES records are required, each for a variable boundary (VB) element side. However, if a group of rainfall/evaporation-seepage element sides appears in a regular pattern, automatic generation may be made. The I-th (I = 1, 2, ..., ) record, in FREE FORMAT, it contains the following variables.

1. MI = Compressed VB element side number of the first element side in a sequence.

2. NSEQ = NSEQ subsequent VB element sides will be generated automatically.

3. MIAD = Increment of MI for each of the NSEQ subsequent VB element sides.

4. I1 = Global node number of the first node of element side MI.

5. I2 = Global node number of the second node of element side MI.

6. I3 = Global node number of the third node of element side MI.

7. I4 = Global node number of the fourth node of element side MI.

8. I1AD = Increment of I1 for each of the NSEQ subsequent VB element sides.

9. I2AD = Increment of I2 for each of the NSEQ subsequent VB element sides.

10. I3AD = Increment of I3 for each of the NSEQ subsequent VB element sides.

11. I4AD = Increment of I4 for each of the NSEQ subsequent VB element sides.

NOTE: A blank line with 11 0's must be used to signal the end of this subset.

(e) River Water Surface Profiles: This data set is required if and only if NRRR > 0. There are NRRR records in this subset. The number of lines in each record depends on NRRP. The I-th (I = 1, 2, ..., NRRR) record, in FREE FORMAT, contains the following variables.

1. THCON(1,I) = Time of the first data point in the I-th profile, (T).

2. HTCON(1,I) = River surface elevation (relative to the common datum of the nodal coordinate system) of the first data point in the I-th profile, (L/T).

3. THCON(2,I) = Time of the second data point in the I-th profile, (T).

4. HTCON(2,I) = River surface elevation (relative to the common datum of the nodal coordinate system) of the second data point in the I-th profile, (L/T).

Up to NRRP data points.

(f) River water surface profile type assigned to each of all NVNP nodes. This data set is required if and only if NRRR > 0. At most NVNP records may be needed. However, automatic generation can be made. Note that this pattern must be repeated NDF times to cover all pore regions. The I-th (I = 1, 2, ..., ) record, in FREE FORMAT, contains the following variables.

1. MI = Compressed VB node number of the first node in the sequence.

2. NSEQ = NSEQ nodes will be generated automatically.

3. MIAD = Increment of NI for each of the NSEQ nodes.

4. MITYP = Type of river water surface profiles assigned to node MI. Enter 0 (zero) if the ponding depth given in subset (g), not the river water surface profile given in subset (e), is to be used for surface water head calculation.

5. MTYPAD = Increment of MITYP for each of the NSEQ nodes.

NOTE: A line with 5 0's is used to signal the end of this data set.

(g) Ponding Depth Allowed in Each of NVNP Variable Boundary Nodes: Normally, NVNP records are needed, one for each of the NVNP nodes. However, if a group of nodes has a regular pattern of ponding depth, automatic generation is made. Note that this patter must be repeated NDF times to cover all of the pore regions. The I-th (I = 1, 2, ..., ) record, in FREE FORMAT, contains the following variables.

1. NI = Compressed VB node number of the first node in a sequence.

2. NSEQ = NSEQ subsequent nodes will be generated automatically.

3. NIAD = Increment of NI for each of the NSEQ subsequent nodes.

4. HCONNI = Ponding depth of node NI, (L).

5. HCONAD = Increment of HCONNI for each of the NSEQ nodes, (L).

NOTE: A line with 5 0's must be used to signal the end of this subset.

(h) Minimum Pressure Head Allowed in Each NVNP Variable Boundary Nodes: Thissub set should be entered similarly as the above subset (g). The I-th (I = 1, 2, ..., ) record, in FREE FORMAT, contains the following variables:

1. NI = Compressed VB node number of the first node in a sequence.

2. NSEQ = NSEQ subsequent nodes will be generated automatically.

3. NIAD = Increment of NI for each of the NSEQ subsequent nodes.

4. HMINNI = Minimum pressure head allowed for node NI, (L).

5. HMINAD = Increment of HMINNI for each of the NSEQ nodes, (L).
