Investigatesare done to know the appropriateness of different shapes of broad crested weirs to substitute
the predictable method of discharge measurement with the help of weir, notch or other dives on site. The weir used on
site also has an independent use as energy dissipater. The properties of the weir crest and step altitude of a broadcrested weir of rectangular cross section and curve portion on the values of depth, discharge coefficient (cd), and the
approach velocity was examines by taking series of laboratory investigation. The dependency of theobservations taken on
model parameters for discharge was examined and the magnitudes were associated with those of the traditional
rectangular broad crested weir and venturiflume.
