Session C2: Translating Regulation Into Outcome, Andy Don

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The Environment Agency (EA), a nondepartmental public body charged with environmental protection and regulation in England, implemented strategy and process to deliver tangible improvements to eel passage and screening across a range of impacting Sectors and individuals.

The Eels (England and Wales) Regulations 2009 came into force on 15 January 2010 to support the UK in implementing EC Council Regulation (1100/2007). Under this European Regulation, the UK must take actions to halt and reverse the decline in the European eel stock, aiming to meet a target set for the number of mature adult eels leaving each river basin to …

Session E2: Benefits Of New Management Of The Haringvliet Sluices And The Effects On Fish Migration, André Breukelaar

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The Rhine West Water Council is responsible for the regional implementation of the Water Framework Directive (WFD) and contributes to the River Basin Management Plan of the Rhine. The Rhine-West river basin is situated in the most western part of the Netherlands. It is highly industrialized and urbanized. Yet it is of major ecological importance with several ecologically important areas and main open connections from the sea to the rivers of the Dutch Delta. Thus, the Rhine-West region is a gateway to Europe, both economically and ecologically.

In this duo-presentation, we would like to focus on:

• The Rhine-West Roadmap …

Session B1: Lessons Learned From Tropical Storm Irene 2.0: How Flood Resiliency Benefits Of Stream Simulation Designs Are Changing Policy Within The U.S., Nathaniel Gillespie, Robert Gubernick, Dan Cenderelli, Mark Weinhold, Brian C. Austin, Daniel Mckinley, Amy Unthank, Kurt Gernerd

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

Stream simulation design is a geomorphic, engineering, and ecologically-based approach to designing road-stream crossings that creates a natural and dynamic channel through the crossing structure similar in dimensions and characteristics to the adjacent, natural channel, allowing for unimpeded passage of aquatic organisms, debris, and water during various flow conditions, including floods. A retrospective case study of the survival and failure of road-stream crossings was conducted in the upper White River watershed and the Green Mountain National Forest in Vermont following record flooding from Tropical Storm Irene in August 2011. Damage was largely avoided at two road-stream crossings where stream …

Session D1: Towards Effective, Bi-Directional Selective Fish Passage, Thomas Pratt, Rob Mclaughlin, Andrew Muir

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Barriers interfere with aquatic connectivity by preventing or limiting migratory fishes from spawning and other life history processes, and there is increasing pressure to restore connectivity. However, conflicting management objectives exist in many jurisdictions where barriers to fish movement inhibit the restoration of native fishes but protect native fish communities above barriers from undesirable invasive species. In the Laurentian Great Lakes, barriers are an important management tool in the control of invasive Sea Lampreys. Sea Lampreys remain highly destructive in the Great Lakes, and are a constant threat to a 7 billion dollar fishery. Developing selective, effective bi-directional fish …

Session D1: Experimental Study On Flow Patterns In Vertical Slot Fishways, Verena Höger, Martin Henning, Franz Nestmann

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The vertical slot fishway is one of the most commonly used fish passage facilities in Germany. The flow conditions within fishway play an important role in the establishment of ecological connectivity, because they determine whether fish can pass, with regard of their given swimming performance.

Earlier studies have shown that two different types of flow patterns, separated by a transition area, may develop in the pools depending on the width-to-length (B/L) ratio of the pools and the slope of the fishway.

In order to gain insight in the formation of different flow patterns, an extensive study of different geometric …

Session A1: Effects Of Sluices On Migrating Elvers And Other Fish In A Dutch Salt Water / Fresh Water Gradient, Bas Van Den Boogaard, Joost Bergsma, Bart Schaub, Lucienne Vuister

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

Many of the formerly gradual transitions between marine and freshwater habitats have been severely altered by man-made constructions. In the Netherlands, water managers are implementing numerous measures to decrease the negative effects of these barriers on fish migration (e.g. constructing fish passages). Adjusting sluice management to restore a salt water / fresh water gradient, however, is a novel way of accommodating fish migration. To effectively apply this measure, more knowledge is required on how fish migration is influenced by sluices.

At Spaarndam (the Netherlands), a complex of pumping stations and sluices separates salt water and fresh water. Within this …

Session B1: Fish Passage In Large Rivers: Challenges And Solutions, Walter Reckendorfer, Gerd Frik, Roland Schmalfuss, Sabine Käfer, Gerog Loy

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

Understanding and facilitating fish passage in large rivers is a major challenge. This challenge stems in part from the scarcity of surveys of large river, due the inherent difficulties associated with studying them. In addition large rivers host a great number of fish species differing in size, ecological requirements and swimming abilities. Notwithstanding the limited information regarding these topics, EU and national legislation require passage facilities for all species and size classes to reach the “good ecological status” till 2027.

VERBUND, the largest power plant operator in Austria, is responsible to implement these measures on a variety of big …

Session B1: Fish-Friendly Management Of First Dams In The Tidal Area Of The Gironde Estuary (France, Sw), Vanessa Lauronce, William Bouyssonnie, C. Rigaud

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

The particular case of the first dams met by the European eel migrating in the tidal area of the Gironde estuary is examined here. For these obstacles, typological elements are proposed, based on the nature of the hydraulic dams, but also on that of its downstream and upstream areas. Various technical tries are already performed to minimize impact of these dams, in tidal areas. These obstacles exist to prevent and limit entrance of salt or brackish water in the swamp and to prevent floods. Glass eel and tidal and marine young species colonize theses areas carried by the stream. …

Session C1: Assessing Longitudinal Connectivity Affected By Cross-Sectional Barriers In A Riverine Bidirectional Network, Gonzalo Rincón Sanz, Carlos Alonso, Joaquín Solana, Santiago Saura, Diego G. De Jalón

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Disruption of longitudinal connectivity is a main problem in most of the world rivers. Spain, as a country with one of highest rates of cross-sectional obstacles per river, needs a strategy to restore longitudinal connectivity in riverscapes. Graph theory based approaches have proven as a suitable tool to measure the connectivity in the landscape. Unlike terrestrial habitats, where it has been profusely used, riverine systems still remain scarcely studied under this focus. There is a need to adapt the currently available knowledge on terrestrial habitat connectivity assessment to the management of river networks. In our study the broadly used …

Session D1: Modelling The Efficiency Of A Vertical Slot Fishway For Anadromous Fishes, Gabriela R. Cardoso, Ana F. Belo, Catarina S. Mateus, Carlos M. Alexandre, Esmeralda Pereira, Ana Telhado, João Ferreira, Felisbina Quadrado, Bernardo R. Quintella, Pedro R. Almeida

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Several types of fish passage are increasingly being installed in river barriers to restore the longitudinal connectivity of fragmented riverine habitats. A vertical slot fishway installed in the Açude-Ponte weir at Coimbra (River Mondego, Portugal) was monitored to model the efficiency of this infrastructure for anadromous fishes (i.e., sea lamprey Petromyzon marinus L.; allis shad Alosa alosa L. and twaite shad Alosa fallax Lacépède, 1800) throughout 2013 and 2014 spawning seasons.

Fish passage was assessed using a video recording system. Simultaneously, eight abiotic parameters, considered as potential predictors of fishway’s use by anadromous fishes, were continuously recorded during …

Session B1: German Participatory Forum On Fish Protection And Downstream Migration, Eleftheria Kampa, Ulf Stein, Stephan Naumann

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

Fish protection and downstream fish migration has been an item of intensive and often controversial discussions in recent years in Germany, both from an environmental policy perspective and a technical point of view. In response, the Federal Environment Agency, with support from Ecologic Institute, initiated a Forum on Fish Protection and Downstream Fish Migration in 2012.

The Forum includes participants from federal and regional water resource management authorities, nature and angler NGOs, consultancies, water managers and hydropower. More than 200 stakeholders have engaged in a dialogue process on the following jointly-identified key topics: environmental policy and legal framework; river …

Session D1: Classification Of Flow Patterns In A Nature-Oriented Fishway Based On 3d Hydraulic Simulation Results, Rebekka Czerny, Peter Oberle, Franz Nestmann

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

In order to fulfill the requirements of the EU Water Framework Directive concerning the restoration of fish passage in rivers, various types of (near-natural and technical) fishways have been built in recent years. For optimization of planned structures as well as for monitoring of the performance of existing fishways, their hydraulics has to be studied. 3D hydrodynamic numerical modelling is a useful tool to predict hydraulic quantities and analyse flow pattern. Many studies using hydraulic simulations deal with technical fishways. In contrast, nature-oriented fishways have rarely been numerically modelled so far.

In the framework of R&D activities at Karlsruhe …

Plenary Speaker: Universal Lessons From Fish Passage Research, Design And Application In Australia, Martin Mallen Cooper

International Conference on Engineering and Ecohydrology for Fish Passage

Dr. Mallen-Cooper has been a specialist fishway biologist for 30 years and has designed over 200 fishways in Australia and overseas, from fish locks and fish lifts on large dams to low-level pool-type and nature-like fishways. His approach to projects is to clarify ecological function, develop migration models and integrate fish behavior into all aspects of dam, weir and fishway design. A key aspect of this is integrating biology, hydrology and hydraulics, which has led to new approaches and applications in fishway design and improved ecological function.

In the last 10 years Dr. Mallen-Cooper has had a significant focus on …

Plenary Speaker: Fish Passage In An Era Of Broken Rivers: New Approaches A Reason For Hope?, Zeb Hogan

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Fish passage in an era of broken rivers: new approaches a reason for hope?

In an era of decline of large-bodied, migratory fishes, river connectivity has been shown to be increasingly important for the conservation of native biodiversity. From North America to Asia, Europe to South America, issues with river connectivity influence – for better or worse - the life cycle, and population status, of migratory fishes. In the Mekong River Basin, the world’s largest fishes, including the Critically Endangered Mekong giant catfish Pangasianodon gigas and giant pangasius Pangasius sanitwongsei, face extinction because of mainstream dams on the lower …

Jonathan will present his experience using biochar as a powerful growing medium in aquaponic systems. Aquaponics being the culturing of fish and plants together ecologically in closed systems (the merging of aquaculture and hydroponics). Biochar grow media benefits aquaponic systems in multiple ways, including its light weight, local sourcing, bio-chemical qualities, ecological nature, and affordable price. Through pictures and discussion he will show how his experiment has faired, and offer ideas for economic opportunities of aquaponic biochar in the Northeast.
