Influence of inclined bed channel on
characteristic of flow for step broad–crested weirs was investigated
experimentally. Discharge coefficient,
water surface profile and Froude number were calculated experimentally.The results showed that water surface
profiles were smooth and continues having a descending trend from the point of
measurement taking the shape of the weir with a steep drop near the downstream
face of the weir. Increasing effective head to crest height ratio (He/Y)
and channel bed slope (So), increased the coefficient of discharge
(CD) up to 5%. Also it was found. that for small values of (Fr2),
the weir performance tends to the ideal .and with increase (Fr2),
the discharge coefficient (CD) decrease for all weir models, because
the discharge and the velocity heads increases. Empirical equation was
developed on the basis of obtained results.
