Abstract

Flow measurement devices can cause significant errors in inflow-outflow
channel water loss measurements. The device effects, caused by the
increased water surface elevation upstream of a device, must be subtracted from
measured losses to correctly estimate conveyance water loss. Methods to calculate
device effects are given. In channels with small slopes and in which loss
rates increase sharply with water surface increases, inflow-outflow loss measurements
should be made in long channel sections with devices which create
as little head loss as possible.
