IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Scope

Hydraulic Structures includes a broad spectrum of applications to engineering practice. The purpose of the Committee is to champion the subject area of hydraulic structures in an era of increasing specialization in the hydraulic profession. There are important new developments in the planning, design, construction, and life cycle maintenance of hydraulic structures.
The Hydraulic Structures Committee was established with the following objectives:
  • to champion the area of hydraulic structures in an era of increasing specialization;
  • to bridge the gap between researchers and practitioners;
  • to identify knowledge gaps where hydraulic research can be applied;
  • to address the subtle changes in the use of hydraulic structures to manage water in an environmentally sound manner;
  • to provide a solid knowledge and experience base for design of hydraulic structures;
  • to encourage continuing education in hydraulic structures through specialty conferences; short courses and educational curriculum;
  • to gather competent data bases from laboratory and field to encourage hybrid modeling (numerical/physical);
  • to collaborate with other organizations in the advancement and understanding of hydraulic structures in the natural environment.
The flow fields in and around most hydraulic structures are complex, three-dimensional, and highly turbulent and can cause phase changes resulting in air entrainment or sediment transport. Safety evaluation of existing structures is another growing area of need as materials age, hydrologic methods improve, and evaluation technologies improve.
The topic of hydraulic structures is changing as an engineering and research area. In recent years, the focus has expanded to include water management as well as improvements in the design, construction and operation and maintenance of locks, dams, spillways, and outlet works. The Committee will embrace the traditional use of hydraulic structures in water resource development and in addition focus attention on the role hydraulic structures have in improving water management practices, water quality, and restoration of natural habitats. It is hoped that a practice oriented research agenda will draw the attention of the global design community.
To meet these objectives, the Committee presents workshops and symposia to advance the science and understanding of hydraulic phenomena near hydraulic structures, which will assist in applying new technologies to practice. Examples of past workshops and symposia include:
  • International Workshop on Hydraulics of Stepped Spillways (March 22-24, 2000, Zurich, Switzerland)
  • Special Seminar on Key Hydraulic Issues of Huge Water Projects (September 17-18, 2001, Beijing China)
  • International Symposium on Hydraulic and Hydrological Aspects of Reliability and Safety Assessment of Hydraulic Structures (May 29-June 2, 2002, St. Petersburg, Russia)
  • International Workshop on Rock Scour due to High Velocity Jets (September 25-28, 2002, Lausanne, Switzerland)
  • International Conference on Hydraulics of Dams and River Structures (April 26-28, 2004, Tehran, Iran)
  • International Junior Researcher and Engineer Workshop on Hydraulic Structures (September 2-4, 2006, Montemor-o-Novo, Portugal)
  • International Symposium on Hydraulic Structures (October 12-14, 2006, Cuidad Guayana, Venezuela)
  • 2nd International Junior Researcher and Engineer Workshop on Hydraulic Structures (July 30 – August 1, 2008, Pisa, Italy)
  • 3rd International Symposium on Hydraulic Structures (October 20-23, 2008, Nanjing, China)
It is our desire to collaborate with other IAHR Committes as well as international associations such as the Environmental and Water Resources Institute (EWRI) of ASCE to organize workshops and symposia as well as technical publications, thus improving the practice of hydraulic engineering as it relates to structures.

Research Agenda 

  • Study the interaction between near-field and far-field interaction - The flow within and around hydraulic structures involves near-field hydraulics, which is often embedded in a far-field environment, and the interaction between the two fields is of great interest in the combination of near-field scale model and far-field numerical model.
  • Fluid phase changes and multiphase flows – The flow is in most cases complex, three-dimensional, highly turbulent, and the pressure and turbulence in the field can cause phase changes and air entrainment or sediment transport.
  • Effect of hydraulic structures on natural systems – Interaction is needed with other disciplines such as environmental scientists (fishery issues associated with hydraulic structures), soil and rock mechanics (scouring criteria), etc.
  • Safety criteria for existing dams with respect to climate change and extreme floods, which can require new innovative structures, modifications to structures or changes in operational procedures.
  • Sluices and navigation locks in salt-fresh water environments.
  • Management of reservoir siltation caused by hydraulic structures.
  • Dam breaches and their effect on downstream valleys in terms of erosion and aggradation.
  • Advancement of research and technology in hydraulic engineering and structures, combining leading research scholarship and world-class engineering practice.
  • Consider developing a web-based international Network on hydraulic structures where practitioners can exchange engineering practice and research ideas.
  • Learning from past incidents.
