The review explored various flumes used for open channel flow measurement and provided insight into operational concepts, discharge measurement, range of flow, head loss requirements, degree accuracy submergence, advantages, limitations use. reviewed included; Parshall flumes, Montana Cutthroat H-flumes, Trapezoidal Replogle-Bos-Clemmens (RBC) Palmer-Bowlus Central Baffle (CBF). Based on the stage relationship, have a reasonable ± 10 % over wide flows. RBC are most accurate (± 2 %). For flows that deal with lot sediments, self-cleaning capability except flumes. H-flumes low resistance to submergence. submergence transition is only 25-30 %. highest (90 CBF need be improved in order capability. Submerged corrections developed published effectively operate minimal loss. has an selection appropriate type flume channels.
