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.

Quantification of tidal power in a highly dynamic estuary
Author : STEPHEN NASH(1) & ANNA PHOENIX(2)
ABSTRACT
Site selection for tidal turbine deployment is primarily dependent on the available tidal stream power. A number of different approaches have been used in literature to estimate the available resource. The main differences between approaches are the type of velocity data used and the means of calculation of the available power. A weakness of many of the published resource studies is that they ignore the directionality of the tidal flows. This research presents a methodology for determining the tidal stream resource in an estuary which incorporates the prevailing direction of flow at a site and therefore results in a more accurate assessment. Two traditional methods of resource assessment are employed and the results compared with those of using the authors¡¯ methodology. The Shannon estuary on the west coast of Ireland is used as a case study. Relative to the authors¡¯ approach, the other methods of assessment were found to significantly overestimate the available resource.
