7.2Timeseries Tool

WHY?
The Timeseries Tool can be used to view timeseries directly for data stored in different IDF-files. These can be combined with timeseries that are associated to IPF-files.

WHAT?
The Timeseries Tool allows you to point at a particular location inside the full extent of an IDF-file with time-dependent data. iMOD will construct a timeseries for that particular location by collecting all data from the other related time-dependent IDF-files. Related time-dependent IDF-files have identical names but have a different date string. A date string is an eight digit continuous number, e.g. 20091231 meaning the 31\({}^{th}\) of December 2009. It is not necessary to load all related time-dependent IDF-files in the iMOD Manager. At least one is sufficient to view the entire timeseries.

Example of IDF-files (A,B and/or C) available in the iMOD Manager prior to the start of the Timeseries Tool:

pictures/h5/image60.png

HOW?
To start the Timeseries Tool select Toolbox from the main menu, choose Timeseries Tool. Alternatively, you can click the Timeseries button (  pictures/h5/image604.png ) at the main toolbar. In both cases, you should select at least one IDF-file in the iMOD Manager that has a date notation in its name. This is a continuous number with eight-digits (yyyymmdd), e.g. 20110115. In this case, it represents the 15\({}^{th}\) of January, 2011. If iMOD can not find such a date notation somewhere in the filename (in at least one of the selected IDF-files), the following window will appear and the Timeseries Tool will not start.

Warning window:

pictures/h5/image605.png

If a proper IDF-file(s) has been selected in the iMOD Manager, the following window will appear.

Available Dates window:

pictures/h5/image606.png

Use ALL available dates (297-files)

Select this option whenever you want to display timeseries for the entire time window that iMOD found.

Select PART of all available dates

Select this option to specify a different time window. This may gain processing time as less files need to be opened.

From:

Enter the start date of the time window. On default it displays the earliest date of the data.

To:

Enter the end data of the time window. On default it displays the latest date of the data.

Frequency of input used for time series

Select this option to decrease the number of dates used, e.g. by entering the value 2 iMOD will skip each second available date of the time series.

OK

Click this button to start the Timeseries Tool for the selected time window. The Available Dates window will close.

Help …

Click this button to start the iMOD Help Functionality.

Cancel

Click this button to close the Available Dates window; the Timeseries Tool will not start.

Note: You should select at least one IDF with date information in its file name, other IDF-files that are selected without a date information, will be displayed as time-constant. In this way you can easily make a combination with time-variant information (e.g. heads) and time-invariant information (e.g. surfacelevel).

Note: When you select an IPF with associated time series, these time series will be displayed simultaneously with those obtained from the IDF-file(s). In case you specify one IDF and one IPF, the option to compute differences between them becomes available.


7.2.1Draw Timeseries

The Draw Timeseries window consists of three tabs. The IPF Options tab is only available when IPF-files are loaded.

Draw Timeseries window, Graph tab:

Timeserie Hovering
Click this button to start the hovering of timeseries. Move your mouse over the main graphical window to compute the timeseries. The current location will be highlighted on the map and the corresponding timeserie(s) will be displayed immediately. iMOD will try to read and process the entire timeseries (could be more than one) within one second. If this fails, the progress bar shows the amount of data that could be processed within this time limit.

Progress bar in Graph tab:

pictures/h5/image611.png

To complete the timeseries, you need to press the left mouse button in the main graphical window. If the progress bar is absent, the timeseries are displayed completely. To stop the Timeserie Hovering you need to press the right mouse button.

Save As
Click this button to save the current graph to a comma-separated-values file (*.CSV) to be read by Excel. When the option Compute Residuals on the Preferences tab is selected, an extra column will be added with the computed differences. Moreover, whenever the option Plot as duration curve on the Preferences tab is selected, the export will describe the duration curves instead. Time-invariant IDF–file(s) will be exported with their time constant values. The first column of the export file prints the data (yyyymmdd), the second, third and so on (as many columns as files active in the Timeserie Tool) print the timeserie(s).

Example of a comma-separated-values file by the Timeserie Tool:

Note The number of records in the export file depends on the dates that contain data for each column. In case column 2 has no data (NoDataValue=-999.99) than the computed difference is nodata too. Since, column three has data, the 14\({}^{th}\) of April, 1989 is exported whatsoever.
