Analysis Water Years
The Water Year Analysis feature can isolate specific years for comparison and analysis. This is useful for figuring out what a reasonable future projection might be given historical trends. If it is shaping up to be a dry year one might look at historical dry years to see what might be possible given historical observations and/or operations.
The options available for this analysis feature is shown below. An explanation of what each option does directly follows.
Time Window Options
- This allows you to isolate certain years out your dataset for comparison.
Additional Lines
- You may select to plot a 30-year average given your data.
Year Type
- This one is fairly self explanatory. You can either display your data in water years (Oct-Sep), calendar years (Jan-Dec), or a custom range of your choosing.
