The reported study presents testing and evaluation of a modified BCW flume. Using this flume, the discharge of four lined watercourses was measured and compared with the flow rate estimate by Manning's equation. The discharge of the flume was found to deviate by ± 2% from the estimate. This deviation could be considered negligible. Under the given hydraulic and boundary conditions, BCW flume was found to operate satisfactorily. It is simple to construct and economical as compared to other measuring devices under similar conditions.
