R Documentation
Continuously monitored (daily) data for 06610000 Missouri River at Omaha, Neb.
Description
Continuously monitored (daily) streamflow and sediment data for U.S. Geological
Survey streamgage 06610000 Missouri River at Omaha, Neb., and streamflow and
sediment anomalies.
Usage
cqwMoRivOmaha
Format
A data frame containing 2,922 daily observations of two hydrologic variables,
streamflow and sediment, and streamflow and sediment anomalies.
There are eight variables.

dflow
numeric
daily mean streamflow, cubic feet per second
flowa30
numeric

flowa1
numeric
1-day streamflow anomaly
dsed
numeric
daily mean sediment concentration, milligrams per liter
seda30

Details
The streamflow and sediment anomalies were generated using the R package
waterData (Ryberg and Vecchia, 2012).
Note
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.
