New-stage discharge relationship for weirs of finite crest lenght

The flow process of weirs of finite crest length is analyzed on the basis of the dimensional analysis and incomplete self-similaritytheory. The crest length is incorporated in the functional stage-discharge relationship for weirs of finite crest length. The theoretically deducedstage-discharge formula was then calibrated using the experimental data compiled in this research. According to the current experimental datait is also concluded that the performance of the proposed stage-discharge formula is better than the previous dimensional stage-dischargeformulae. Also, the proposed stage-discharge formula is applicable for all types of the weirs, i.e., long-crested, broad-crested, short-crested,and sharp-crested ones
