Relevance. At present the application of numerical analyses to real problems of dam engineering has suffered at times from the gaps between the specialists of mathematical modeling and dam engineers and managers. The first group usually includes information system specialists because they are able to develop the computer models to their full potential. The professionals belonging to the second group often prefer to revert to traditional methods of calculation and empirical methods based on their proven experience. The aim of the work - based on recommendations of International workshops seminars, organized by the ICOLD Committee on Computational Aspects of Dam Analysis and Design, help dam engineers to interact with mathematical modeling specialists and to work with them without language barriers or gaps in knowledge. In this relation the assessment of reliability and applicability of numerical analyses of dams allows engineers to develop the optimal dam design. Methods. Assessment of the reliability of numerical methods of analyses of dam behavior was based on data of 10 International benchmark-workshop seminars, organized by the Committee in Italy (1991 and 1992), France (1994 and 2009), Spain (1996), USA (1999), Austria (2001), Romania (2003), China (2005), Russia (2007), in which specialists of these countries also took part.

Актуальность. В настоящее время применение численных расчетов к реальным проблемам плотиностроения часто страдает от расхождений между специалистами по математическому моделированию и инженерами и менеджерами по плотинам. Первая группа обычно включает в себя специалистов по информационным технологиям, так как они способны разработать эффективные компьютерные модели для численных расчетов плотин. Специалисты второй группы часто предпочитают обращаться к обычным методам расчета и эмпирическим методам, основанным на их проверенном опыте. Цель - на основе рекомендаций Международных рабочих семинаров, организованных Комитетом СИГБ по компьютерным аспектам расчета и проектирования плотин, помочь инженерам по плотинам взаимодействовать со специалистами по математическому моделированию и работать с ними без языковых барьеров или расхождений в знаниях. В этой связи оценка достоверности и применимости численных расчетов плотин позволяет инженерам разработать оптимальный проект плотины. Методы. Оценка достоверности численных методов расчетов поведения плотин основана на данных десяти Международных рабочих семинаров, организованных Комитетом СИГБ в Италии (1991 и 1992), Франции (1994 и 2009), Испании (1996), США (1999), Австрии (2001), Румынии (2003), Китае (2005), России (2007), в которых специалисты этих стран также принимали участие.
