Here’s how to use it:
- Enter standard information: Provide a name and an optional description for the time series.
- Choose between using an external file as the data source or entering data directly into the grid.
- If using an external file, locate the file and ensure it follows the required formatting.
- For direct data entry, input values into the grid. Include date (if needed), time, and numerical values.
- You can view a graphical plot of the data by. Editing options like copy, delet, insert, and paste are available via a right-click menu in the grid.
- Confirm your edits by pressing OK or cancel them by clicking Cancel.
Note: Time series data can be described either by calendar date/time of day or as elapsed hours since the start of the simulation. For rainfall time series, only periods with non-zero rainfall amounts need to be entered. VOSWMM uses interpolation for other time series types to estimate values between recorded points.
required formatting
Time Series Files are external text files that hold data for VOSWMM’s time series objects, such as rainfall, evaporation, and inflows. These files need to be created and edited outside of SWMM using a text editor or spreadsheet software. To link a time series file to a specific object, you can use VOSWMM’s Time Series Editor.
The format of a time series file involves one value per line, and you can insert comment lines (starting with a semicolon) or blank lines. Time series values can be in date/time/value format (e.g., 7/21/2004 20:30) or time/value format (e.g., 52.333 for 2 days, 4 hours, and 20 minutes). Additional dates are needed only when a new day starts in the date/time format.
