Robustness quantification for navigation locks that are part of the primary flood defense: A study into the effect of increasing the reliability requirement of structural elements on the robustness of the structural system

Robustness is a hard-to-grip concept within engineering. This master thesis uses a framework to quantify the level of robustness that has been proposed by the Joint Committee on Structural Safety to assess the influence of the reliability requirement of a structural element. The lock complex at Weurt (the Netherlands) has been used for a case...

Design and feasibility study for the application of an inflatable rubber structure in a navigation lock

Introduction In navigation locks levelling is executed under free flow. The net flow from the upper section into the lower section of the waterway is considered as a water loss. An innovative water saving concept is an IRS Lock. IRS stands for inflatable rubber structure. The concept consists of an air filled IRS applied in a lock chamber. In...
