1.5 Day Workshop – Saturday June 24-Sunday June 25

Description

It is time for stream channel assessment and design to move beyond a template approach to a method that explicitly uses water and sediment supply in an explicit framework that incorporates uncertainty, supports alternatives analysis, and accommodates traditional hydraulic geometry relations in an appropriate supporting role. This short course presents a design approach that begins with specification of desired channel dynamics and then uses estimates of water and sediment supply to explore design alternatives. The method builds on the classic definitions of threshold and alluvial channels. A threshold channel is one for which the bed material is immobile at a design discharge. An alluvial channel is one for which transport capacity is balanced against the rate and grain size of sediment supply. A third type of channel is defined and combines the first two – over-capacity threshold – in which transport capacity exceeds supply but design flows do not exceed threshold limits for channel erosion. This type of channel is more common than often realized, is unintentionally designed in many cases, and offers both advantages and disadvantages that can only be weighed if the design objectives are specifically defined. Uncertainty in water and sediment supply is explicitly included in assessing channel performance. A risk framework is developed for threshold channels and alluvial channels are evaluated in terms of the probability of undesirable aggradation or degradation. At small sediment supply rates, channel performance is relatively insensitive to uncertainty in sediment supply and principles of flow competence may be used to design a threshold-like channel. At large sediment supply rates, the potential for storing or evacuating channel-changing quantities of sediment is much larger. A computational tool will be presented that assists in estimating the sensitivity of channel performance to uncertainty in sediment supply. The tool includes river state diagrams useful for reconnaissance evaluation and channel stability diagrams useful at the planning stage.

The method presented includes a number of important components: (i) it is based on specified channel behavior, such that rates of water and sediment supply and their uncertainty can be directly incorporated in the design process, (ii) it accommodates traditional empirical observations of channel geometry in an appropriate supporting role, (iii) it uses a surface-based mixed-size sediment transport relation that accommodates transient conditions, and (iv) it identifies design channel geometry using the full range of water and sediment supply, rather than a single design discharge.

Reading materials will be distributed in advance of the course. Spreadsheet models will be made available and used in classroom portion of the course. Students should bring their own laptops for use during the workshop. An afternoon field trip will provide an opportunity to evaluate the principles taught in the course for local stream channels.

1 Full Day Workshop – Sunday June 25

Description

GEO Morphix Ltd. is partnering with the Natural Channel Initiative to provide a full-day workshop on ‘Fish Passage, Fish Behaviour, and Fish Passage Design’, with particular emphasis on applications in channel design and stream crossings. This course outlines concepts in hydraulics, aquatic ecology, fish behavior and physiology, fish passage design, and real-world applications.  The first half of the course will follow a seminar-style format.  The second half will include physical demonstrations to reinforce the foundations covered during the seminar.

Specific topics include:

• Introduction to simple, open-channel hydraulics
• Fish behaviour
• Techniques to mitigate fish passage issues
• Eco-hydraulics and the application of simple hydraulic models to address fisheries questions
• Field measurement techniques
• Modelling of hydraulics to assess fish passage

This seminar provides professionals with a greater understanding of hydraulics and fish passage as they pertain to channel design and stream crossings. Fish behaviour/response to different flow conditions is also reviewed as it provides tools to understand and assess fish passage. Several simple hydraulic approaches for assessing fish passage are reviewed. Methods for instream treatments (e.g. vortex weirs, armoured beds) are also discussed in the context of channel hydraulics and ecological benefit. This course assists agency and municipal personnel to ensure that the proper questions are asked when assessing channel designs and other activities that impact fish passage.

Physical Demonstrations

Physical demonstrations with different culvert and channel configurations will reinforce the discussions on hydraulics and fish passage discussed in the first session.

Learning Objectives

Upon the completion of this workshop, participants will be able to:

• Understand and appreciate hydraulic calculations and their application in assessing fish passae
• Understand and apply strategies to address hydraulic constraints for passage

Instructors

This workshop is prepared and delivered by Dr. Paul Villard of GEO Morphix Ltd and Mark Heaton of Ontario Streams.

Dr. Villard has extensive local and international experience in fluvial geomorphology and channel design from both an academic and applied perspective. His recent activities include design and implementation of large-scale valley and channel realignments and research on fish passage, habitat suitability, and stability of natural channel designs.

Mark Heaton is an experienced fish and wildlife biologist with a demonstrated history of working with the government sector. As one of Ontario Streams’ founding members, he was instrumental in steering the organization towards specializing in rehabilitation of aquatic habitats. An aptitude for creative mitigation and habitat restoration in urban design, his career experiences include numerous  planning and design, construction, maintenance operation and monitoring projects for fish passage in the watersheds of the GTA. Heaton is a co-author of Ontario Stream Rehabilitation Manual and was the recipient of Conservation Ontario’s 2017 Latornell Leadership Award.
