Side weir calculation

WebFor V-notch weirs, full contraction is produced when the distance b. from each side of the weir notch to each side of the weir pool is greater than 2H. For a 90° V-notch weir, the flow width at head level is equal to 2H. Therefore, the weir may be considered to be fully contracted when the ratio B/H > 6, i.e., when H/B 0.167. Webto side weirs in canals where the flow remains subcritical. The flow profile parallel to the weir, as illustrated in Figure A3.1, shows an increasing depth of flow. The side weir shown …
