International Good Practices of Embankment Upgrading with Limited Footprint Increase

This report investigates how embankments in Bangladesh could be upgraded with no or limited footprint increase. Many Bangladesh embankments need to be upgraded to improve flood protection. Traditionally, embankments are upgraded by adding more soil, heightening the crests while simultaneously widening the embankment maintain slope stability.<br/...

Dike stabilisation under uplift conditions using stabilisation columns: A study on the technical potential of stabilisation columns for improving inner slope stability under uplift conditions

The low lying areas in the Netherlands often consist of soft and low permeable soils like clay and peat on top of a sand layer. Due to high water pressures at the interface between the permeable sand layer and the low permeable top layers, the effective stresses decrease, which can cause lifting of the low permeable top layers. As a consequence...

Benefit of starting early: Impact of monitoring and soil investigation during different project phases of dike reinforcement.

To fulfil the new safety standards of the Netherlands against flooding in the future, a great deal of work needs to be performed to prepare the flood defences system, at a quicker pace than is currently achieved. For this reason the HWBP is researching methods which can improve the efficiency of dike reinforcement projects. This thesis was...

Evaluation of sheet pile behavior based on Eemdijk monitoring data

From the 3500 kilometers of primary flood defenses in the Netherlands, a third does not comply with the current standards. As a result, over 700 kilometers will be strengthened in the upcoming years. Traditional strengthening of dikes consists of strengthening with soil and requires space that is often not available. Further strengthening of...

Influence of Monitoring on Investment Planning of Flood Defence Systems

Many flood defences in the Netherlands will have to be reinforced in the coming decades. Many dikes do not fulfill the safety standard due to geotechnical failure modes, largely due to epistemic, reducible uncertainties. . The Value of Information is a measure to indicate beforehand whether an investment towards reducing epistemic uncertainty is...

Spatial integration of dike reinforcements: Development of a method that compares the spatial influence of design alternatives

In the Netherlands, a new assessment method for the required safety level of primary flood defences is introduced in the Water Act. It is estimated that currently roughly 1900 kilometres of flood protection does not meet the safety requirements for the future (Jonkman, Jorissen, Schweckendieck &amp; Van den Bos, 2017). Past flood defence...
