Abstract: According to the characteristics of fine-grained depositing sediment, and in association with the theory of flow along pipeline with uniform draw-off, the solution of engineering sediment problem by using desilting corridor along the path is proposed. The structure, operational mode, and advantages of the desilting corridor are described, and a solution for potential problems is put forward. Similar methods in engineering application are briefly introduced. If further studies and the following results could prove that the desilting corridor has good applicability, the measure could be an important desilting approach in waterways, reservoirs, power plants, ship locks and other hydraulic projects.

Key words: desilting corridor along the path, desilting hole, sediment deposition, waterhead, pump station
