How to load in dynamic rain and simulation time (Water Overlay)
Revision as of 11:39, 12 June 2019 by Rudolf@tygron.nl (talk | contribs)
Rain and simulation time of a Water Overlay are related, and must be configured simultaneously. Changing the duration of the rain (or associated dry periods) automatically changes the simulation time, and vice-versa.
Editor → Current Situation (Ribbon tab) → Overlays (Ribbon bar) → The Water Overlay (Left panel) → Configuration Wizard (Right panel)
How to load in dynamic rain and simulation time:
- Prepare a CSV file with a sequence of times and rain amounts. (See example below.)
- Open the configuration wizard of the Water Overlay.
- Continue to the step concerning weathers.
- Select the weather event you wish to update, or select "Add" to create a new one.
- Set the "Rain over Time" setting to "Custom".
- Select "Import". This will open the "Import CSV" window.
- Select "Import new CSV", and open your file.
- Answer the prompts regarding the format of your file.
- Verify that the data has been loaded in as expected. Take special note of the time format.
- Close the "Import CSV" window.
- Verify that the total simulation time and the total rainfall match your expectations.
- Close the wizard.
Example CSV
A CSV file may look as follows:
3600,0.03 7200,0 9000,0.03 108000,0.06
Loading in this file, using seconds as the time unit, would lead to the following sequence of events:
- During the first hour of simulation (3600 seconds), a total of 30mm of rainfall occurs
- Between the first and the second hour of the simulation, no rainfall occurs
- During the next half hour, the rainfall doubles in intensity compared to the first hours (the same amount of rain in half the time)
- During the last half hour, the rainfall doubles in intensity again compared to the previous half hour (double the amount of rain in the same amount of time)
- After 3 hours has passed (10800 seconds), the simulation is over. The total simulation time is 3 hours.
