Tainter Gate:

Radial gate most commonly used on navigational projects. In its simplest form, a tainter gate is a segment of a cylinder mounted on radial arms that rotate on trunnions anchored to the piers. Because of its simple design, relatively light weight, and low hoist-capacity requirements, the tainter gate is considered one of the most economical and most suitable gates for controlled spillways.

T-type flood walls:

Cantilever T-Type Reinforced Concrete Wall consists of a concrete stem and base slab which form an inverted T. The structural members are fully reinforced to resist applied moments and shears. As necessary to resist under seepage during a flood event, a steel sheet pile cutoff wall is cast into the base slab of the T-Wall. The T-wall may need to be supported on a pile foundation if soft soils exist. The piles can be made of either steel or concrete and derive their support to the T-wall from friction of the soil surrounding the pile or through end bearing at a deeper stronger soil strata.
