Abstract: 

Hydraulic structures, such as dams fulfill many societal functions including water supply, flood mitigation and generation of hydropower. Their safety is paramount and a failure can be catastrophic. The design of hydraulic structures must therefore be conducted with the highest technical standards using state-of-the-art measurement approaches. Despite their significance, current design practice for flood release and energy dissipation facilities is limited to small scale physical modeling combined with numerical modelling while significant limitations exist due to scale effects and missing prototype validation data. In recent years, some new advances have been made in the use of instrumentation and post-processing methods that can provide more confidence in the design of hydraulic structures and that may change the way we design structures in the future. Herein, this talk provides an overview about recent developments in the instrumentation relevant for hydraulic structures including phase-detection intrusive probes, remote sensing with LIDAR and camera technology as well as lagrangian-type sensors for fish safety assessment.

Abstract: 

Until the late 1990s, the particles found in the upper tropospheric / lower stratospheric (UTLS) were an area of uncertainty in atmospheric science. At about the same time, instruments were developed that could be flown on high altitude research aircraft to determine particle composition and large chambers were built that allowed us to mimic the conditions in this remote region of the atmosphere. This talk will review how aircraft measurements and laboratory studies have been, and will continue to be, used in concert to better understand atmospheric chemistry, precipitation and our climate.
