Scope

Hydraulic structures engineering is one of the most important fields of civil and environmental engineering with challenges arising from new and complex environmental issues, refurbishment of aging infrastructure and increasing resilience to climate change. Such challenges will require the combined efforts of both researchers and practitioners in future years.  The purpose of the Hydraulic Structures 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 that are to be addressed by both researchers and practitioners. To help facilitate these efforts, the Hydraulic Structures Committee has the following objectives:

  • to champion the area of hydraulic structures in an era of increasing specialization;

  • to help with the adaptation of hydraulic structures to reduce footprint and impact and instead harmonise with the surrounding environment;

  • to bridge the gap between researchers and practitioners by engagement with government water agencies, participation in codes and standards committees and writing and promoting technical publications;

  • to identify knowledge gaps where hydraulic research can be applied;

  • 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 the laboratory and field to encourage advancements in modelling, theory, observation and technology;

  • to collaborate with other organizations in the advancement and understanding of hydraulic structures in the natural environment.

Active Research Areas

The flow fields in and around most hydraulic structures are complex, three-dimensional, highly turbulent and can cause phase changes resulting in air entrainment or sediment transport. To provide important design advancements, research of hydraulic structures engineering must therefore be addressed from various perspectives.

The multidisciplinary research activities of the Hydraulic Structures Committee are guided by the sustainability of hydraulic structures engineering in the 21st century addressing important research questions in an era of rapid technological development, urgency in reducing the carbon footprint and maintaining a secure water infrastructure for humanity. In particular, the Committee actively pursues research in the following areas:

Theories

Theories

Providing fundamental solutions for complex three-dimensional flow processes associated with hydraulic structures including multiphase flows and process-based approaches for turbulent flows.

Education

Education

Educating the next generation of hydraulic engineers and contributing to life-long learning within the hydraulic structures community.

Modeling

Modelling Tools

Exploring the newest physical and numerical modelling tools to expand the fundamental and applied knowledge base for betterment of hydraulic structures design.

Multidisciplinary

Multidisciplinary Research

Conducting multidisciplinary research at the interface of hydraulics and (fish) biology and/or chemistry to provide guidelines for fish passes at hydraulic structures or for hydraulic structures in wastewater treatment plants.

Technology Advancements

Technology Advancements

Embracing technological advancement and employing and developing new instrumentation to provide unique insights into flows across hydraulic structures.

Observations


Observations

Continuing the tradition of sound physical modelling together with advanced numerical modelling tools to provide practical solutions to water infrastructure design, while embracing field and full-scale observations of hydraulic structures to bridge the validation gap.

Current Practices and Design Standards


Current Practices and Design Standards

Applying best standards for current practice and to enhance these standards for future challenges to provide practical solutions to a changing climate and associated impacts on hydraulic structures.

Regulations and Requirements

Regulations and Requirements

Improving current legislation to embrace the need for more sustainable and nature based hydraulic structure solutions for the benefits of future generations.

Collaborative Activities

It is our desire to collaborate with other IAHR Committees as well as international associations such as the Environmental and Water Resources Institute (EWRI) of ASCE or the International Commission on Large Dams (ICOLD) to organize workshops and symposia as well as technical publications, thus improving the practice of hydraulic engineering as it relates to structures. Our Committee also hosts the Working Group on Reservoir Sedimentation, which was formally launched in 2019 during the 38th IAHR World Congress in Panama.  

Phil H. Burgi Best Paper Award

Given the 20th anniversary of the IAHR Hydraulic Structures Technical Committee in 2018, the Leadership Team decided to create the Philip H. Burgi Best Paper Award, named after the first chair of the Technical Committee Philip H. Burgi. This award aims at rewarding the best technical paper presented during the International Symposium on Hydraulic Structures.

The award has been delivered for the first time during the 7th International Hydraulic Structures Symposium in Aachen. The recipient receives a certificate and possibly a gift. The previous winners are:

  • ISHS2022: Mauricio Angulo, Arturo Rivetti, Cecilia Lucino & Sergio Liscia, 'Anti vortex device to operate pump intakes below the minimum submergence' and Akash Jaiswal, Zulfequar Ahmad & Saroj Mishra, 'Effect of diameter and inlet-depth on hydro-suction performance of a suction pipe'

  • ISHS2020: due to COVID-19, no award was presented

  • ISHS2018: Svenja Kemper & Andreas Schlenkoff, 'Numerical simulation of intake structures like street inlets with supercritical flow conditions
