Building Resilience: Analyzing Beira’s Drainage Network and Flood Management: The impact of failure mechanisms on flooding in informal settlements

This research analyses and evaluates the performance of the drainage system in Beira, Mozambique. It considers its formation, maintenance, failure modes and connections, to recommend improvements on its performance. The research identifies six primary failure modes - vegetation overgrowth, human interference, waste accumulation, sedimentation,...

Flood Risk Prediction under Global Vegetated Hydrodynamics: A Bayesian Network

The increasing frequency and intensity of extreme events due to global warming and climate change is increasing flood risk. To act, rather than react, nature-based solutions (NBS) involving vegetation and wetlands are being explored on top of conventional solutions like dikes. WHY? There was a dire need for global study quantifying the potential...

Quantifying the effect of woody vegetation on the wave loads on a dike using remote sensing: Large scale physical model tests

It is already acknowledged that Nature-based Solutions can be used to attenuate waves, however it is still uncertain to what extent the vegetation can contribute to decreasing the flood risk. So far mainly small-scale tests have been performed to quantify wave attenuating properties of vegetation. To quantify the effect of more extreme wave...

Reliability of willows for wave load reduction on river dikes: Design and maintenance principles for willow vegetation based on the quantified natural and knowledge uncertainties

Flood defenses are important to keep large parts of the Netherlands dry. These primary flood defences<br/>are every twelve years assessed on safety during the Dutch national safety assessment. In 2017, the new<br/>safety standards (WBI2017) were introduced. These stricter standards caused that in total 251 km of the<br/>primary flood defences...
