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.

Modelling the influence of a tidal barrage on the eutrophication potential and the estuarine ecosystems using a system dynamics approach

ABSTRACT
With a growing need for carbon neutral electricity, the Severn Estuary with its high tidal currents and tidal range could play
an important role by providing tidal renewable energy. Tidal energy usage would change the estuarine conditions
influencing important habitats. A qualitative input-output graph was used as a base description of the structure of the
system. Transfer functions and parameters were derived from DIVAST and other modeling result as well as from empirical
data. Linkages between tidal energy usage, the eutrophication potential and the estuarine foodweb were integrated into
the systems dynamics model for different tidal barrage scenarios including ebb-only and two-way generation. With this
approach it was possible to study connections between more localized effects in the estuary and global effects of tidal
energy along a timeline taking requirements from different stakeholders into consideration. This can help to reduce
negative effects, optimize mitigation measures and improve operation schemes for different tidal power devices.
