Study on the use of cellular cofferdam for permanent hydropower use
Cellular cofferdams are temporary constructions consisting of interlocking steel-sheet piling driven as a series of interconnecting cells. Cellular cofferdams have been employed mainly as provisional “water exclusion devices” for water diversion projects to permit dry construction of dams, locks, bridge footings and piers, hydroelectric power plants, and other in-water structures. This dissertation presents the results of a comprehensive study on the potential use of cellular cofferdams as basis for the design and construction of water retaining structures to sustainably and cost-effectively ...
