Hydraulic structures located in rivers, in coastal areas and even in sewer systems, condition the flow behaviour, affecting sediment transport, water quality, air entrainment and chemical aspects. Flow processes are inherently complex, offering challenges in their observation, understanding, and prediction. Their study in recent years has been supported by a development of monitoring equipment and instrumentation used in experimental facilities within different scales, and in prototype applications. There are also been significant progress in numerical model applications and tools to produce improved meshes and allow enhanced plots.
However there is no data base on the characterization of different hydraulic structures that could facilitate future uses and applications, simulations and predictions. This workshop aims to share data validation results around different types of hydraulic structures from experimental facilities, from prototypes and from numerical models, defining flow patterns, actions on structures and complex interactions. Different approaches to the conventional and innovative aspects of hydraulic structures design, operation, rehabilitation, and interaction with the environment are welcome, namely experimental, theoretical and numerical modelling.
