RSMS Flow Downloader Update 2025
In December 2024, we updated the RSMS flow downloader process. The old C# application will soon be deprecated and was replaced with a Python solution that is very similar to our Riverflows (ORSANCO Flows DB) flow downloader.
Data Validation
- The original flow downloader inserted data for 400 stations, but the new one inserts data for 359 stations. This difference is due to four rivers (Big Sandy, Scioto, Great Miami, and Green) being available in CASCADE, but not in HEC_RAS.
- The original flow downloader's data was available in 6 hour increments while the new downloader's data is in 1-hour increments.
- With 400 stations every 6 hours, we expect 1600 rows per day.
- With 359 stations every 1 hour, we expect 8616 rows per day.
- There is a period of 6-hour and 1-hour overlap. During this time, we can expect 41 * 6 + 8616 = 8780 rows per day.
Flow Values Validation
The following screenshot shows the RSMS Flow data and ORSANCO Flows DB (Riverflows) data side-by-side. From a quick glance, you can tell that the data is comparable.
