Pre-Congress Workshop


Workshops 

  1. Workshop on Nonlinear Weir Design: Theory and Practice

Prior to 38th IAHR World Congress, a full-day workshop on the design and construction of nonlinear weirs will be offered on September 1, 2019.

Inadequate conveyance capacity, significant hydrologic loadings on embankments and structures, and operation and maintenance are common challenges and safety issues that often instigate the need for risk-reduction measures and/or rehabilitation.  Labyrinth and piano key weirs are a particularly efficient approach to reduce these concerns.  These weirs provide a crest length greater than the width of the channel and are commonly used in a variety of applications, including dam rehabilitation and new dam projects.  In some cases, these structures may be complimentary to or even an alternative to gated spillways, which require operation and maintenance and can cause downstream flooding if misoperation or failure occur.  Because of their hydraulic performance and site-adaptive geometries, these types of weirs are of increasing interest to those involved in water infrastructure, including practitioners, researchers, regulators, and owners.  However, these types of weirs have complex geometries and hydraulic behaviors and can pose a challenge when developing an efficient design.

The workshop – organized by experts from research and practice – will cover all relevant stages of a labyrinth and a piano key weir project, from the first theoretical design to detailed studies and practical considerations related to the construction. The workshop will be divided in two parts, each related to a specific type of weir. During both parts, several real examples in France and the USA will illustrate the technical presentations and time will be devoted to Q/A and discussion. An application exercise will be proposed to the workshop participants for both types of weirs. Comprehensive workshop material will be provided to all attendees.

  1. Workshop on Nature Based Solutions

 Nature Based Solutions for water management are increasingly becoming a viable alternative to traditional (‘technical’) solutions in water management. Working with natural processes rather than against them allows for better adaptation to a changing climate and the related water management challenges caused by this. Especially for flood management natural processes such as water retention in upstream catchment areas and the development of coastal and riverine wetlands can help combat the expected changes in flood risk. Also, other Nature Based Solutions to improve e.g. urban challenges related to climate change, droughts and related low flows and water quality issues in rivers can be thought of.

We invite you to a special workshop during the IAHR world congress in Panama in which the potential for Nature Based Solutions are further explored. We will specifically focus on the Middle and South American situation, but of course taking examples from the larger international community as a means to make more professionals in the field of water management aware of these new developments.

  1. Workshop on Engineering The Water Cycle

 The field of hydraulics focuses on the flow and storage of water in catchments, rivers, channels, lakes, estuaries and coastal seas, the source of which is rainfall, hail and snow in the catchments. Global warming and land clearing is leading to large changes in the characteristics of these water sources around the world, large decrease in some areas and large increases in others. Rather than simply trying to accommodate these very dramatic changes in quantity and quality of the water sources, by building more infrastructure, it may be economically more efficient to understand the water source changes and then modify the sources to best match the existing infrastructure and or satisfy development requirements. The purpose of this workshop is to bring together the world’s leading researchers in the field of water resources and catchment management to:

  • Present reviews of the state of the art of the individual components of the water cycle.
  • Identify knowledge gaps in the science of the water cycle.
  • Identify scientific programs needed to make the science accessible to engineers.
  • Outline possible engineering technologies, that if developed will allow the control of the amount, the timing and the intensity of water from the sky, as well as humidity for the benefit of nature and humanity.

It is hoped that this workshop will provide the foundation for a new field of research and so provide a new stimulus for IAHR as an organization, foster interest from academics and PhD students, funding agencies and the general public via international the media.

Deliverables:  Answer to the following questions:

  • Are the currently experienced water source changes severe and urgent enough to warrant concern?
  • Can the observed water source changes be reversed using local engineering technologies, under a business as usual global warming scenario?
  • Is IAHR the right organization to take on these questions?
  • How best to we foster international research and funding coordination?

  1. Sustainable Water Resources Planning and Management Under Climate Change

The short course will be conducted by the members of Water Resources Management Committee Leadership Team (WRM-LT) of International Association for Hydro-Environment Engineering and Research (IAHR) which deals with water related engineering and management under changing climate. The course will be organized and delivered by members of the WRM LT. The duration of the course will be approximately four to five hours before or during the Congress. The short course will also feature case studies and experiences of the researchers from different regions of the world to showcase the variety of climate related issues that are addressed by different countries for water resources management.

The course will focus on the water resources planning and management under changing climate with emphasis on the following topics:

  • Climate Variability and Change: Implications for Hydrologic Design and Water Resources Management
  • Impacts of Climatic and Land use Changes on Hydrologic Cycle.
  • Improving Water Resources Management incorporating Hydrologic Prediction and Climate Information
  • Adaptation to Climate Change- Decision Making and Economic Impacts
  • Climate Change and Strategies for Policy Development
  • Adaptation to Climate Change- Institutional Analysis

Instructors:

IAHR WRM -LT members. Six to seven members of IAHR WRM LT will be lecturing for this short course. http://iahr.org/Portal/About_US/Technical_Division/Water_Resouce_Management.aspx

Short Course Coordinators/Contact:
