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.

A review of recent advances in ecohydraulics
Author : CHRISTOS KATOPODIS
ABSTRACT
Recent ecohydraulic advances in both quantitative ecology and hydraulics have enabled the development of effective
measures to mitigate or compensate for negative environmental impacts of water resources projects. Determining what
drives aquatic species abundance and distribution is a central theme in quantitative ecology, while quantifying species
abilities and behaviour is pivotal in biology. Progress and innovation in instrumentation, especially in tracking and observing
aquatic life in field and laboratory settings, as well as the more quantitative integration of ecological, biological and detailed
hydraulic aspects, have accelerated ecohydraulic advances. The ecohydraulic trinity, dealing with (1) aquatic animal
migrations, (2) e-flows (i.e. instream, environmental, or ecological flow regimes), and (3) river restoration, has made
important contributions to the engineering and management of many projects around the globe. Notable advances have
been made with upstream and downstream movements of biota, especially different species of fish, as well as fish behaviour
observations in rivers, fish passage systems or controlled experiments with fish and velocity fields of high definition.
Sophisticated e-flow methods based on improved scientific understanding have been developed using more complex
ecohydrological statistics, morphodynamic and ice related aspects, as well as thermal, hydrodynamic and habitat suitability
modeling, for different species and stages of aquatic life. Furthermore, advances in habitat enhancements, rehabilitating or
re-naturalizing degraded rivers, or dam removal, have also been made. As a result of scientific advances and developed
technical tools, the interdisciplinary science of ecohydraulics, has made considerable strides forward. Ecohydraulics, which
integrates physical and ecological aspects, even in its present state, enables water use and management, while meeting
conservation objectives for ecosystem health, biological diversity, sustainable populations and recovery of aquatic species
at risk. With further research, particularly on increasingly quantitative ecological and biological aspects, including largescale
field experiments and climate change outlooks, ecohydraulics is emerging with new paradigms to meet the growing
water management and aquatic conservation challenges.
