How do you measure stream flow?
Quick stream flow measuring is best done with a water current meter to measure water current velocity. Stream flow measuring
is easily accomplished using a water current meter and a tape measure. The current velocity meter allows you to measure
stream flow velocity in feet or meters per second and measure water depth in hundredths of a foot up to three feet. The
average stream flow velocity times the cross-sectional area of the stream determines the stream flow measurement in cubic feet or
meters per second. The area for of a channel is known for pipes, or is determined for a stream flow measurement by measuring
the distance from shore and water depth at various points across the stream flow to construct a channel profile. The water
current meter offers two unique methods for determining average water velocity: 1) For small stream flows and pipes, the current
velocity meter may be moved smoothly and uniformly throughout the stream flow profile until a steady average reading is displayed. This
steady reading is the true average velocity for the stream flow. 2) For larger streams, the current velocity meter may be used
to measure a vertical profile of water velocity at several points across a stream channel. The stream flow measurement for the
profile is the sum of the average velocity of each subsection of stream flow times its cross-sectional area. For more information
