Schematization uncertainties in the macrostability safety assessment: Case study for primary dikes in the Alblasserwaard

The current macrostability safety assessment for primary river dike trajectories in the Netherlands is applied to approach the failure probability of a dike during high water events. However, in the current schematization process that is described in the Wettelijk Beoordelings Instrumentarium (WBI) to assess the macrostability, aleatory and...

Assessment method of multiple flood protection improvements in a water system governed by a storm surge barrier: The case of Ramspol Barrier

Climate change is adding more and more pressure to the water systems. The area which is protected by the storm surge barrier of Ramspol have high probability of flooding for climate projections in 2050 and 2100. <br/>Nowadays, the development of the technology is providing with numerous tools and analytical models for the engineers. However, in...

Developing a method to include flood defenses explicitly in flood hazard maps based on limited available information

Flooding is one of the most damaging natural disasters worldwide, and presents a signi_cant risk for a large amount of the global population. For the development of ood disaster management strategies, policy makers make use of ood hazard maps to inform investment strategies to reduce risk. In many current ood hazard mapping methods, the role of...

A new generation flood defences: Dam with tidal power station including pumping capacity: A feasibility and optimisation study

A dam including a tidal power station with pumping capacity is a new type of flood defence. The negative ecological impact normally associated with closure dams is partially mitigated by including a tidal power station in the structure. Water can move through the tidal power station resulting in a reduced tidal stroke at the created lake. This...

Glass Flood Defences: A theoretical and practical assessment of the impact resistance of Glass Flood Defences to floating debris

In the far south of the Netherlands, the erratic river Meuse flows through the landscape. It recently flooded twice in the 1990s, causing much economical damage. Emergency measures, such as a demountable flood wall, were taken to prevent future flooding. And while this solution was to the liking of the inhabitants, the update in the flood safety...

Technical and value obstacles faced by Building with Nature flood defence solutions: A case study on technical feasibility in relation to value conflict in Building with Nature flood defence solutions for the Houtribdijk reinforcement project

Building with Nature (BwN) is a relatively novel way of thinking for flood protection. Unlike traditional flood protection solutions that are poised to bring forces of nature to a halt, the BwN’s philosophy is to use natural dynamic processes for engineering advantage as a protection against natural disasters and events. Yet, the BwN design...

Wind Turbines near Flood Defences: Study on the impact craters of falling nacelles hitting a dike

Building wind turbines near flood defences has numerous advantages over other locations on land. The water authorities, which own the land of the flood defence, will only permit the turbines if the flood protection assessment satisfies the safety standard after the wind turbines have been constructed. There are three types of failure of a wind...
