It is important that those developed models are well validated with measurements to demonstrate the usefulness of the models. This research is a validation of the Delft3D-FLOW model which is a model that is often used in practice. For the validation, detailed measurements of flows through a sharp bend (radius/width < 2 a 3) flume, performed at the EPFL (Lausanne, Switzerland) and Large Eddy Simulations (LES) conducted at the TU Delft are used. The objective of this study is to analyze to what extent Delft3D-FLOW is able to predict the hydrodynamic processes in sharp open channel bends. This study contains the comparison of several important quantities of Delt3D-FLOW simulations, measurements and LES Subject shar-bend flowturbulencesecondary circulationDelft3D-FLOWLESequilibrium-bedhorizontal-bed To reference this document use: http://resolver.tudelft.nl/uuid:00bcacca-f04e-4c17-8955-ad922bf0fbc7 Embargo date 2010-07-07 Part of collection Student theses Document type master thesis Rights (c) 2010 Van Sabben, A.J.
