304 Processing <strong>Modflow</strong><br />
1. Data: NVERTEX<br />
(The following data repeats NVERTEX times)<br />
2. Data: X Y<br />
Explanation <strong>of</strong> Fields Used in Input Instructions<br />
ALL DATA IN THE SAME RECORD ARE SEPARATED BY A COMMA OR BLANK.<br />
NVERTEX is the number <strong>of</strong> vertexs <strong>of</strong> a polyline<br />
X is the x-coordinate <strong>of</strong> the i-th vertex<br />
Y is the y-coordinate <strong>of</strong> the i-th vertex<br />
Observation File<br />
An observation file can be created by the Boreholes and Observations dialog box (see section 3.5) or the Graphs<br />
Viewer (see section 5.6). An existing observation file can be imported into the Boreholes and Observations dialog<br />
box.<br />
File Format<br />
1. Data: LABEL<br />
2. Data: NOBS XXX XXX XXX XXX<br />
(The following data repeats NOBS times)<br />
3. Data: TIME WEIGHT HEAD DDOWN CONC COMPAC PREHEAD SUBSDNS NAME<br />
Explanation <strong>of</strong> Fields Used in Input Instructions<br />
ALL DATA IN THE SAME RECORD ARE SEPARATED BY A COMMA OR BLANK.<br />
LABEL is the file label. It must be PMWIN5000_OBS_FILE<br />
NOBS is the number <strong>of</strong> observations. Maximum number <strong>of</strong> NOBS is 10000.<br />
XXX reserved.<br />
BORENO is the borehole number where the observation is made.<br />
TIME is the observation time, measured from the start <strong>of</strong> the simulation.<br />
WEIGHT is the weight attached to each observation<br />
HEAD is the observed head at time TIME.<br />
DDOWN is the observed drawdown at time TIME.<br />
CONC is the observed concentration at time TIME.<br />
COMPAC is the compaction at time TIME<br />
PREHEAD is the preconsolidation head at time TIME.<br />
SUBSDNS is the subsidence at time TIME.<br />
NAME is the name <strong>of</strong> the borehole at which the observations are made.<br />
Time Parameter File<br />
A Time Parameter file can be saved or loaded by the Time Parameter dialog box (see section 3.3.3).<br />
File Format<br />
1. Data: LABEL<br />
2. Data: NPER ITMUNI<br />
(The following data repeats NPER times)<br />
3. Data: ACTIVE PERLEN NSTP TSMULT DT0 MXSTRN TTSMULT<br />
Explanation <strong>of</strong> Fields Used in Input Instructions<br />
ALL DATA IN THE SAME RECORD ARE SEPARATED BY A COMMA OR BLANK.<br />
LABEL is the file label. It must be PMWIN5000_TIME_FILE<br />
NPER is the number <strong>of</strong> stress periods in the simulation<br />
ITMUNI indicates the time unit <strong>of</strong> model data. (It is used only for printout <strong>of</strong> elapsed simulation time. It does<br />
not affect model calculations.)<br />
0 - undefined 1 - seconds 2 - minutes<br />
