Environmental impact of tidal power in the Eastern Scheldt Storm Surge Barrier : Appendix A: Impact on tidal range due to tidal turbine installation

In this report the results are presented of the investigation to the impact of the tidal turbine operation on the tidal range in the Eastern Scheldt. The study is a continuation of a study conducted in 2014 in which the situation before installation was assessed based on the statistical dependency of the tidal range (i.e. the difference between consecutive high and low waters) between Roompot Buiten and Roompot Binnen. For individual years and relevant periods a (first-order, y = ax + b) linear fit between the tidal differences for the two stations was made. From the analysis the variation over the years was assessed. In this study the analysis was extended with the years 2014, 2015 (before installation) and a representative period for which an array of tidal turbines have been in operation.
