The Flow Analysis Summary Statistics Tool for Excel (‘FASST-X’) is a Macro-Enabled Excel workbook with worksheets to summarize and visualize streamflow data. This tool summarizes continuous daily mean streamflow data into various daily, monthly, annual, and long-term statistics, and a log-Pearson Type III low flow frequency analysis, in both table and plot formats.
For the R package fasstr, see https://github.com/bcgov/fasstr.
Download the latest version of the FASST-X tool here or above, currently dated Jan 2018. Currently works just for Windows-based Excel versions.
FASST-X requires daily streamflow data (in cubic metres per second) to compute summary statistics. This data can be entered on the main ‘Flow Data Input’ worksheet. Other parameters such as station name, drainage basin area (used for yield runoff calculations), selection of calendar or water years, and selection of start and end years can also be selected on the main ‘Flow Data Input’ worksheet.
As there are many Macros and cell formula-based calculations, it may take some time to calculate all the sheets when pressing the ‘Calculate All Tabs’ button (please be patient). To view data availability, press the ‘Update Data Screening Tabs’ to review the data if you wish before calculating everything.
Click through the worksheets to view, copy, and/or export the various result outputs.
| Worksheet Name | Contents |
|---|---|
| Flow Data Input | Streamflow and parameter data entry |
| Data Availability | Counts of available and missing data per year and per month |
| Data Screening | Time series plot and table of the data record provided used for analysis |
| Long-term Statistics | Long-term statistics (mean, median, minimum, maximum) of all daily values for given months and totals. |
| Percentiles & Flow Duration | Percentiles of all daily values for given months and totals. |
| Annual Statistics | Annual statistics (mean, median, minimum, maximum) of all daily values for given years |
| Total Yield & Volumetric Flows | Annual and seasonal total yield ( in mm) and volumetric flows (in cubic metres); annual dates of timing of flows (dates of 25, 33, 50, and 75% of total annual flows) |
| Annual Low Flows | Values and dates of annual 1, 3, 7, and 30-day minimum flows |
| Low Flow Frequencies | Frequency analysis fitting annual low flows to a log-Pearson Type III distribution to determine frequency quantiles (ie. 7Q10) |
| Monthly Statistics | Monthly statistics (mean, median, minimum, maximum) of all daily values for all months for all given years |
| Daily Statistics | Daily statistics (mean, median, minimum, maximum, selected percentiles) of all daily values for each day of the year |
| Daily Cumulative Statistics | Daily cumulative statistics (mean, median, minimum, maximum, selected percentiles) of all daily values for each day of the year |
| Annual Trending Metrics | All annual and annual monthly values from the workbook merged. |
