Continuously monitored (daily) streamflow and sediment data for U.S. Geological Survey streamgage 06610000 Missouri River at Omaha, Neb., and streamflow and sediment anomalies.
cqwMoRivOmaha
A data frame containing 2,922 daily observations of two hydrologic variables, streamflow and sediment, and streamflow and sediment anomalies. There are eight variables.
staid | character | USGS Station identification number |
dates | date | date water-quality sample collected |
dflow | numeric | daily mean streamflow, cubic feet per second |
flowa30 | numeric | 30-day streamflow anomaly |
flowa1 | numeric | 1-day streamflow anomaly |
dsed | numeric | daily mean sediment concentration, milligrams per liter |
seda30 | numeric | 30-day sediment anomaly |
seda1 | numeric | 1-day sediment anomaly |
The streamflow and sediment anomalies were generated using the R package waterData (Ryberg and Vecchia, 2012).
See Ryberg and Vecchia (2012) for more information on calculating the anomalies and for additional references documenting the use of streamflow anomalies in water-quality trend analysis studies.
