CFD analysis to verify the design of a submerged roller bucket for Oxec II, Guatemala

Oxec II is a greenfield hydro project on the Cahabón river in the Department of Alta Verapaz, in the north central region of Guatemala. It is owned by Energy Resources Capital (ERC) and was constructed by the design-build contractor Solel Boneh Guatemala (SBG). Hatch was SBG’s engineer for the project. As well as a brief outline of the project, the paper focuses on studies relating to the flood discharge works, and reasons for the adoption of a submerged roller bucket for the spillway discharge, rather than a stilling basin.
