In such cases, frequent measurements (about weekly) are needed to define how the rating is changing and to define its present condition (fig. 12).

WebMar 6, 2012 · Stream flow, or discharge, is the volume of water that moves over a designated point over a fixed period of time. It is often expressed as cubic feet per second (ft 3 /sec). The flow of a stream is directly related to the amount of water moving off the watershed into the stream channel.

WebWith rare exception, stream discharge is not measured directly, but is computed indirectly from velocity and water level (stage) measurements.
