Towards emission-free sea dike revetments: Making sustainable design choices by employing probabilistic safety assessment and integrating the environmental cost indicator in the parametric design process of sea dike revetments

Large parts of the Netherlands lay below mean sea level. An extensive network of flood protection measures is in place to prevent flooding. Periodic safety assessment and reinforcement are required to guarantee a resilient system. Currently, in the Netherlands, an extensive sea dike reinforcement program is underway to meet the safety standards...

Reducing hydraulic loads on river dikes by construction of longitudinal mounds of local soil

For the past 2000 years river training works have been performed on the Dutch rivers. These training works have shaped the river system of today. Another result of the river training works, especially over the last two centuries, is a decrease in biodiversity. To protect the biodiversity some floodplains in the Netherlands have been classified...

Fragility Curves for Dikes in the Western Scheldt: Assessing the Applicability of Typology-Based Fragility Curves in assessing Dike Reinforcement Cost for Coastal Dikes

The sea level is rising, possibly by one meter, by the end of this century. The Netherlands is preparing for this scenario through Kennisprogramma Zeespiegelstijging (KP-ZSS). One of the goals is to determine the hydraulic effects of sea level rise (SLR) on the current system. For the flood risk analysis within<br/>KP-ZSS, the current strength...

Financial feasibility of large-scale adaptation strategies for future SLR in northern Europe: NEED vs dike reinforcement

The effects of climate change are felt all around the world. An increased sea level goes hand in hand with an increased risk of flooding. To combat this, the coastlines must be reinforced to withstand future sea levels. However, repeatedly reinforcing coastlines to keep up with the sea level rise (SLR) could prove extremely costly. An...

Final Report Levee Challenge: Team Hans Brinker

In this assignment we simulate a two meters wide dike stretch which is subjected to overflow. Three failure mechanisms could occur due to overflow: full erosion of the soil of the dike, macro instability of the levee if too much soil is eroded away, leading to insufficient counterweight on the inside of the levee, and surface slip failure due to...

Enhancing reliability of dikes: An approach for assessing benefits of pore pressure monitoring and pressure relief wells in spatially variable soils

The Netherlands is a country prone to flooding. Recent assessments led to the insight that protection levels of many flood defences should be increased. Integrating reinforcement measures is a difficult task as many dikes are situated in densely populated areas. Conventional reinforcement measures include berm construction or the implementation...

The capabilities of the Plaxis Shotcrete material model for designing laterally loaded reinforced concrete structures in the subsurface

A hot topic in the Netherlands is the safety reassessment of dikes. Currently several (river)dikes are being reinforced to withstand a given normative high water level. The environment of those dikes is often characterised by small floodplains and urban areas right next to the dike, wherefore standard geo-technical measures cannot be applied....
