Simulation of flooding due to embankment breaches by Delft3D Flexible Mesh: Case study of coastal area in Shanghai

As a low-lying city, Shanghai faces threats from typhoon and spring tide under the condition of climate change and land subsidence. With high water level at the toe, the sea embankment is likely to be overtopped and breached, finally resulting in inundation inland.  The objective of this research is to study climate change...

Behavioural analysis and modelling of family gathering during the 2011 Tohoku tsunami evacuation

The conventional evacuation modelling assumes that that family members are to be together in the face of tsunamis and evacuate as a household or each person evacuate individually. This assumption, however, can cause an inaccurate prediction when taking family gathering behaviour into account, which was reported to have occurred during the 2011...

Multi-Hazard Risk Assessment due to Hurricane Activity: Case Study of St. Martin, the Caribbean

Every year hundreds of thousands of people are affected by natural disasters that occur due to various physical phenomenon. They include earthquakes, tsunamis, volcanic eruptions, and hurricanes. In this research the focus is on hurricane events and the impact they have on a community. The ability for a community to bounce back is defined by...

Structural damage to Dutch terraced houses due to flood actions

’De Watersnood van 1953’, the largest Dutch flood in recent history, caused the death of 1795 people in the Netherlands directly from the flood conditions, while in the UK, 315 were recorded. Most of them were among those whose residence collapsed due to high water depth, quick rise rate of the water or strong flow velocity. Based on historical...

Tidal energy generation in Kalpasar

In the future, two enormous challenges face humanity: decreasing the carbon emissions and supporting the growing energy demands in the developing regions of the world. These challenges highlight the need for a greater amount of implementation of renewable energy projects. This thesis tackles one such potential project, the modeling of a tidal...

Undular bore development over coral reefs: An experimental study

A series of laboratory experiments were designed for a schematized 1/20 fringing reef. Both regular and bichromatic wave experiments were carried out. The focus lies on the regular waves experiments. Six regular wave experiments were carried out. During the first two experiemnts, cnoidal waves were generated with typical swell scales, while the...

Experimental research on hydrodynamic failure of river bridges on spread footings

Collapse of partially or fully submerged river bridges as a result of river floods is investigated. To this end, post-failure analysis of a bridge in Japan’s Iwate Prefecture that collapsed in 2013 is conducted. Failure of this particular bridge is atypical because piers have also toppled over, which can be attributed to the spread footing...

Modular Hybrid Coastal Protection Structure: Pilot site: Montego Bay, Jamaica

Tourism is one of the main sources of income of Jamaica. . However, at the moment the beaches are retreating. An example is the erosion of Hellshire Beach, showing a retreat of ten meters in only seven years. To preserve the beaches effectively, a new concept is requested. The main requirements of the system are wave attenuation and the marine...

Offshore pumped hydropower storage: Technical feasibility study on a large energy storage facility on the Dogger Bank

To combat global warming a transition towards renewable energy sources (RES) is essential. Although RES have much lower life-cycle emissions, they do not offer a continuous and fully predictable output like their fossil-fuelled counterparts. Energy storage is paramount in order to include the growing share of these intermittent sources into the...
