COLUMBIA RIVER VELOCITY-DEPTH
Data on the velocity (ft/sec) of water versus depth (feet)
in a channel were acquired at a station below
the Grand Coulee Dam at a distance of 13 feet from the edge of
the river.  Modeling water velocity in a channel is important when
calculating river discharge. (Reference: Savini, J. and Bodhaine, G. L.
(1971), Analysis of
current meter data at Columbia River gaging stations, Washington and
Oregon; USGS Water Supply Paper 1869-F.)
