Hydraulic Structures: a Challenge to Engineers and Researchers

The IAHR Hydraulic Structures Section, jointly with the Instituto Superior Técnico (IST) and the Portuguese Water Resources Association (APRH), organised the international workshop, which addressed conventional and innovative aspects of hydraulic structures design, operation, rehabilitation, and interaction with the environment. The main themes of the workshop embraced the hydraulics of dams and hydropower schemes, river structures, hydraulic structures in urban drainage and sewer systems, as well as coastal protection systems. Eight countries - Australia, Germany, Italy, Netherlands, Portugal, Spain, Switzerland, and the USA - were represented in the event.

Workshop topics included : Research Quality, Publications and Impact in Hydraulic Engineering, Dynamic Behaviour of Jets Issued from Howell-Bunger Valves, Experimental Investigation of Air Circulation Patterns in Classical Hydraulic Jumps, Labyrinth Spillways Design Methods and Consideration of Non-Standard Approach Conditions and Geometries, Discharge Capacity and Residual Energy of Labyrinth Weirs, Energy Dissipation in Vertical and Stepped Sewer Drops in a Circular Channel, Hydrodynamic Pressure Field on Steeply Sloping Stepped Spillways, Experimental Investigations on the Stability of Riprap Slope Protection Layers on Overtoppable Earth Dams, Non-Aerated Skimming Flow Properties on Stepped Chutes over Embankment Dams, Determination of Design Parameters for Coastal Dikes on the German North Sea, Contribution to the Design of Artificial Surfing Reef Breakwaters for Coastal Protection, Waves caused by Landslides into Reservoirs and their Impacts on Dams, Advanced Post-Processing and Correlation Analyses in High-Velocity Air-Water Flows, PIV Limitations in Water- Pump Intake Measurements, Technologic Innovation in Data Acquisition Systems applied to Environmental Monitoring, and Photographs of Hydraulic Structures.

Each paper was peer-reviewed. The full proceedings are freely available online.
