Unazuki Dam, Gravity dam in Kurobe, Japan

The concrete structure of Unazuki Dam extends 190 meters in length and rises 97 meters above the Kurobe River, controlling water flow through its massive frame.

The construction of Unazuki Dam, completed in March 2001, marked the final addition to a series of five dams along the Kurobe River system.

Engineers and water management professionals from various regions visit the dam to study its advanced sediment control methods and technological implementations.

The dam maintains a reservoir capacity of 24.7 million cubic meters and reduces peak water discharge from 6,900 to 700 cubic meters per second.

Annual coordinated flushing operations between June and August align with natural flood periods to maintain sediment balance throughout the river system.
