To remove one of the remaining bottlenecks on the Common Meuse, a hydraulic structure needs to be built in a levee near Heerenlaak. This document is a dissertation on the subject of this hydraulic structure, consisting of a labyrinth weir integrated in a culvert. A tentative Qh-relation was derived by Flanders Hydraulic Research during a desktop study. Due to the uncertainties of this study, additional research is required.
To estimate the stage-discharge relation of the hydraulic structure, experimental measurements have been performed on a scale model of the proposed design and a variety of other configurations. Conclusions can be made regarding the different regimes which occur in the stage-discharge relations by comparing the results of the different configurations. Where possible, theoretical formulas are compared to the experimental data.
Based on the results obtained from the scale model tests and using the conclusions drawn from a literature review, an estimation of the discharge capacity of the design is given and recommendations for possible improvements and additional research are made.
