José Rocha Afonso
Institute of Water (INAG)

Dams and appurtenant hydraulic structures in Portugal. Some recent projects

José Rocha Afonso
José Rocha Afonso received a degree in Civil Engineering from the Technical University of Lisbon, in 1976. He worked in the fields of dam safety and hydraulic projects, in the Ministries of Public Works and of Environment. Since 1993, in the latter ministry he headed departments dealing with projects and works in rivers and coastal areas, dam safety and infrastructure management, at the Institute of Water (INAG), the National Water Authority. In 2005 he became Vice-President of INAG, with a scope of intervention broadened namely to water resources planning and management and Water Directives, both at national and European Union levels. He participates in several professional and international associations, including the Portuguese Water Resources Association and the Portuguese Water Partnership. He currently is the Secretary General of the Portuguese National Committee on Large Dams.

Dave Campbell
Schnabel Engineering, USA

Spillway hydraulic modelling – Personal adventures and peeks behind the curtain

Dave Campbell
Dave Campbell is Schnabel Engineering’s Director of Dam Engineering. He has more than 35 years of experience in dam engineering and water resources planning, including in-depth capabilities for water supply planning, designs for new and existing dams, hydrologic analysis and hydraulic design.  Dave founded dam engineering services at Schnabel Engineering in 1994. Schnabel’s Dam engineering services has grown to include 75 dam engineering personnel, who are regularly supplemented by the firm’s geotechnical, geostructural and geologic engineering expertise.

Dave has broadly published on dams and contributed to an AWWA-sponsored water resources planning book, Water Resources Planning – M50 (2001, 2007 and 2013 in progress).  He led development and presentation of a FEMA sponsored one week course on dam safety. Additionally, Mr. Campbell has been honored with the ASDSO National Award of Merit and Villanova University’s John Gallen Memorial Award for his contributions to dam safety.

Laurent David
Institut Pprime, CNRS- Université de Poitiers – ENSMA, France

Fishway hydrodynamics and global approaches for insuring the upstream migration around dams

Laurent David
Laurent David is Professor of fluid mechanics at the University of Poitiers since 2006. His PhD degree and his accreditation diploma to supervise research (HDR) were obtained respectively in 1996 and in 2005. Since 2010, he is at the head of the Hydrodynamics and Environmental flow section composed to 14 permanent researchers and involved in environmental hydrodynamics, open channel flows, solid transport and mixing, and flow rheology.

The research interests cover fundamental aspects of unsteady flows with moving structures, turbulent free-surface flows, environmental flows and mixing through different national and European programs. Fundamental contributions to optical flow measurements include PIV and stereoscopy PIV measurement techniques and recently free surface measurement and volumetric measurement techniques.
