摘要:The main lines of work on numerical simulation at INA Hydraulics Lab during its three decades of existence are briefly reviewed. They are rooted in four main subjects: hydrodynamics, sediment dynamics, pollutant dynamics and heat dynamics. Software development and applications are also mentioned. It is emphasized that these lines of work are problem-driven, i.e. they are defined by the practical requirements of the social media. This policy has led to participation in a variety of studies of significant social impact, which are briefly mentioned. The present lines of work are not only directed to the use of more sophisticated techniques, but also to exploit existing tools in order to provide results ready to be used for long-range planning by decision-makers.
