Biography

My contribution both as engineer and researcher is to understand the middle ground between man and nature. Flood defences protect us from the water but are also integrated with many other functions such as housing and nature. Depending on the location, some functions are more common than other ones (see photo). This shared-use of the flood defences often comes with conservative estimates for a robust design that guarantees the flood safety. While having multi-functional flood defences generally impose restrictions on the design, some elements in the natural foreshores or flooded areas near the dike can contribute to reducing flood risk. For example, vegetated foreshores in coastal areas can damp the amount of wave energy that reaches the dikes. Aside from natural values, coastal salt marshes can also capture clay over time which may be used in future dike reinforcements. With the new probabilistic risk approach recently adopted in the Netherlands, we may be able to quantify the effects on flood safety of both standard and nature-based reinforcement measures. Yet, an integrated risk assessment framework is required.

The objective of my research project is to gain more insight into the shared-use of flood defences on flood risk reduction. I do so by using the new probabilistic risk approach to determine the safety level of flood defences that are shared with traditional functions such as housing. I further assess the effects on flood safety of some nature-based measures applied in innovative dike reinforcements.

All-Risk

Since 2017 new safety standards came legally into place following a risk-based approach. Under the umbrella of the Flood protection program (in Dutch named to as HWPB), the ambition is to offer basic protection for the population living behind the dike and prevent substantial economic damage. Therefore, the government will reinforce about 2/3s of the 3.500 kilometers of the primary flood defences over the next two decades.

Our shared ambition with the Flood protection program naturally led to the question: How can we support the reinforcement of flood defences at an increased pace and decreased cost while considering the implementation’s governance and legal aspects? This question initiated the five years’ research of the All-Risk program, starting from 2017 until the end of 2021.
