Project: Six inch modified Parshall Flume (Portable)

Parshall Flume

The USGS Hydrologic Instrumentation Facility has supplied a three inch portable Parshall flume for many years. The three inch flume is an important hydrographer's tool to measure discharge in channels that are not suitable for measurement with mechanical or acoustic velocity meters. Periodically we receive requests for a six inch version of the portable Parshall flume for those situations when the capacity of the three inch flume is not enough. The dimensions of the three inch portable Parshall flume and the dimensions for the six inch flume listed in the USGS Techniques of Water-Resources Investigations (TWRI) Book 3 Chapter A14 have been combined together to produce drawings for an all new six inch portable Parshall flume that can be used to make discharge measurements.
