 promoting mathematical modelling improvements to approach safety- related problems that cannot at present be properly analyzed;  issuing guidelines to be used for educational purposes in the current practice. The Committee is strongly committed to contribute in the process of a suitable transfer of experience, skill and knowledge across generations. The work done by the Committee during its long activity has given rise to the issuing of three Technical Bulletins (N. 94, Computer software for dams. Validation, 1994; N. 122, Computational procedures for dam engineering, 2001; N. 155, Guidelines for use of numerical models in dam engineering, 2013). Moreover, the Committee has promoted the organization of benchmark- workshops (BWs), with the aim to guide dam engineers in the correct use of computer programs. The benchmarking program started in Bergamo (Italy) in 1991 and continued up to 2017 with the 14th workshop held in Stockholm. Bergamo (Italy), 1991-1992. Seismic analysis of Talvacchia dam: the dam seen from the left abutment; the FE model; some results of the seismic analyses The benchmarking activity represents a reference for the whole dam community, and in particular for young engineers engaged in the challenging task of dam safety assessment and design. To facilitate the accessibility and a critical review of the proceedings related to the 14 BWs held so far, a capitalization activity of the tremendous amount of data at disposal has been recently started. The preparation of a new Bulletin to provide a synthesis of the BWs results and comments on the progresses achieved on the numerical modelling methods and the strategies to be used to tackle most of the dam engineering problems is foreseen for the end of 2019. 2
