Reedijk, BAM Infra TU Delft Faculty of Civil Engineering an Geosciences Date: 12-1-2018 3 4 PREFACE After more than seven years studying at the faculty of Civil Engineering at the TU Delft, this master thesis finalizes my master programme in Hydraulic Engineering at the Delft university of Technology. This master thesis represents a conceptual design of a Tidal Power Plant in the Brouwersdam, in the province Zeeland, the south-west of the Netherlands. In the search of a satisfying graduation topic, I found myself back at BAM, one of the largest contractor of The Netherlands. After completing an internship at BAM International in Dubai in 2015, I decided to elaborate my thesis at BAM Infraconsult. BAM provided me with a design topic, a Tidal Power Plant in the Brouwersdam. Special thanks for Bas Reedijk and Erik ten Oever for providing me with information and their knowledge of previous performed research to the Tidal Power Plant. Secondly, I would like to thank my daily supervisor from the Delft University of Technology: ir. W.F. Molenaar. Thanks to his advice, knowledge, encouraging me to keep up the pace and the pleasant meetings, I was able to write this thesis. I would also like to acknowledge Dr. ir. Drs. C.R. Braam for helping me with the structural elements in this thesis. Furthermore, I would like to thank Prof. dr. ir. S.N. Jonkman for chairing my committee and for the critical advice during the meeting. Finally, during the months spent at the section Coastal Engineering at BAM Infraconsult in Gouda, I had the pleasure of collaborating with many interesting and very kind colleagues. My gratitude extends to every one of the Coastal Engineering department for contributing to the pleasant time I have had. 5 CONTENTS Summary
