# US Water Network Observed and Inferred Flows

Rising, James

This dataset provides a synthesized national record of river gauges.  It includes inferred flows which are based on the structure of the river network and empirical flow relationships.  In total, the network contains 22619 gauges (or virtual junction gauges) and over 1 million years of monthly data.

The dataset is provide as a saved data file for R, flowdata.RData, containing two variables: nodes and allflow.

nodes describes each gauges or virtual junction gauge in the water flow network, representing a combination of gauges from multiple sources.  The source is specified by the collection column, as follows:

• rivdis: From the RivDIS dataset, at http://iridl.ldeo.columbia.edu/SOURCES/.UNH/.CSRC/.RivDIS/index.html?Set-Language=en
• usgs: GAGES II river gauge
• reservoir: National Inventory of Dams reservoir
• usgsres: USGS gauged reservoir
• canal: Canal cross county boundaries
• junction: Junction node added to capture the structure of rivers from HydroSHEDS

The colid specifies the ID of the gauge within its collection, and combined collection and colid are unique.  The location of the gauge is specified by the latitude lat and longitude lon.  The elevation is provided in meters in column elev.

The flow data is contained in the allflow matrix.  This matrix has a column for each node (as many columns as there are rows in nodes), and a row for each month starting from Jan. 1915.  All the flows are in units of m^3 / s.
