When the TWC lies below the JHC at all discharges, the problem can be ...
Explanation:

Provisions to solve the problem when the TWC lies below the JHC:
- Provision of a ski-jump bucket: A ski-jump bucket is designed to redirect the flow of water in a way that prevents scouring and erosion of the river bed. This provision helps in maintaining the proper alignment of the river and ensures the stability of the structure.
- A sloping apron below the river bed: Constructing a sloping apron below the river bed helps in dissipating the energy of the flowing water and reducing the velocity of the water to prevent scouring. This provision also helps in protecting the river bed from erosion.
- Provision of roller bucket type of energy dissipator: Roller bucket energy dissipators are designed to break the momentum of the flowing water and reduce its velocity. By incorporating this provision, the energy of the water is dissipated safely, preventing any damage to the river bed.
- Construction of a subsidiary dam: Building a subsidiary dam helps in regulating the flow of water and preventing excessive erosion of the river bed. This provision ensures that the water is managed effectively to maintain the stability of the structure.
Therefore, the combination of these provisions (iii, iv, and v) can effectively solve the problem when the TWC lies below the JHC at all discharges.
