Time-Series Data

Time-series data can be imported from files or directly defined in the time-series dialog boxes (see fig-time-series-editor) that are available within the different boundary-condition dialog boxes. A time series consists of a user-defined number of data pairs (time, value).

Figure 1: The time-series editor

There are three different options in MINEDW for the input of time-series data (see fig-time-series-editor):

Constant:

The boundary-condition data is constant, regardless of time.

Annual:

The values are defined for a year and repeated each year for the entire model-simulation time period.

Varied:

The values are defined over time.

Figure 2: Time-series input options

Time-series data can be imported from a text file. The plot on the left-hand side displays the time-series data. For any period during which the pump is turned off, enter “0” for wells that are defined as “Pumping Rate” or “LPE” wells (lowest pumping elevation wells) and “N/A” or “-99999999” for wells that are defined as “Specified Head” wells. Time-series data can also be exported to a .DAT file. After any modifications, make sure to click “Apply” to save the changes.
