2. Sealing of weir body and weir wing underlay.
3. Overflow of fixed weir sill of movable weirs with high degree of submerge by downstream water, calculation of overflow consumption curve.
4. Surface hydraulic jump, divergent stilling pool.
5. Calculation and design of inflatable weirs – design of fixed low sill and calculation of consumption curve of overflow.
6. Calculation and design of inflatable weirs – design of inflatable structure and calculation of consumption curve of overflow.
7. Calculation and design of downstream apron including lining.
8. Design and calculation of inflatable weir equipment.
9. Informative static calculation of flap gate.
