CFD modelling for dams and reservoirs – best practice workflows, specification and review

This paper identifies the need for industry guidance for the application of computational fluid dynamics (CFD) to the dams and reservoirs industry and lays out the primary components of such a model study, providing guidance for procurement and review. First, workflow is discussed to give an overview to those unfamiliar with the process. The key areas are explicitly explained for the layperson. The later part of the paper identifies key issues that reviewers should focus on and discusses areas such as accuracy. Support is offered to owners and those procuring model studies in the form of sample text recommended for specifying CFD studies. Finally, the paper recommends a high level of quality control and expert review when issues of dam safety are concerned.
