Target class: dam construction project Context triple: [Boulder Canyon Project, instanceOf, dam construction project]
-
A.
concrete dam
A concrete dam is a massive engineered barrier constructed primarily from concrete to hold back and control the flow of water in a river or reservoir.
-
B.
arch dam
An arch dam is a curved concrete dam that transfers the water pressure primarily into the abutments through arch action, allowing a thinner structure than gravity dams.
-
C.
lock and dam structure
A lock and dam structure is an engineered system on a waterway that combines a gated dam to control water levels with a lock chamber to raise and lower vessels between different elevations for safe and efficient navigation.
-
D.
reservoir dam
A reservoir dam is a large engineered barrier built across a watercourse to store and regulate water in an upstream reservoir for purposes such as water supply, flood control, irrigation, and power generation.
-
E.
infrastructure project
chosen
An infrastructure project is a large-scale, organized effort to plan, design, and construct foundational physical systems—such as transportation, utilities, and public facilities—that support a community’s or region’s economic and social activities.
- F. None of above.
