Flow Characteristic in Parshall Flume-A Review

Accurate flow measurement is very important for proper and equitable distribution of water among water users. Due to increasing utilization and the value of water, measuring techniques become more important and necessary information concerning the volume of available water is very useful in planning for its future use and distribution for hydraulic engineers. There are several types of flow measurement devices currently in surface flow among the major types of measurement devices used in surface water are: weirs, flumes, current meters, turbine meters, ultrasonic meters, pitot tubes etc. The most common water measurement devices are sharp crested weirs and Parshall flumes. This paper describes about the flow characteristics for Parshall Flume.
