摘要：The sharp-crested weir is the most commonly used device in channels for flow measurementand regulation, due to its simplicity. Attempts have been made to study flow over different shapes ofnormal, side and oblique weirs. This research carried out for development of inclination-flow model tomeasure flow over inclined rectangular weir. In the present study, four different inclined weirs areconsidered for validation purposes. The calculated over flow parameters are compared against 2Dnumerical data as well as experimental studies which is showed that: The higher inclined-weirdischarging index associated with angle will help to improve discharge coefficient
