In this paper, the outflow process of a weir with irregular shape is studied using the dimensional analysis and the incomplete self-similarity theory. The new stage-discharge is theoretically deduced and it represents a comprehensive equation describing the weir outflow process for a full range of flow and geometric variables of the weirs. Finally this stage-discharge relationship is calibrated using measurements available in literature.
