If a weir floor is built as a continuous reinforced structure with the divide piers, so that their weight keeps it safe against uplift, what is it called?
Correct answer B. Non-gravity weir
Explanation
In a non-gravity weir the floor is thinner and relies on reinforced concrete bending strength and the weight of the piers, rather than its own mass, to resist uplift.
