Role of household climate change adaptation in reducing coastal flood risk: The case of Shanghai

Climate change intensifies the frequency and severity of floods - the most devastating and costly climate-induced hazard. Government adaptations such as dikes or beach nourishments are important, yet insufficient in the face of worsening hazards. They reduce the hazard probability, but the local actions at the household level determine the...

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...

Urban flood hazard management - Case study: Shanghai

Shanghai is one of the numerous megacities worldwide that experience severe flood events triggered by torrential rainfall. To deal with the undesirable consequences of these events and mitigate the flood hazard, the research of flood reduction measures is necessary. In this effort, the hydrodynamic modelling is a useful tool.<br/>In this master...

Rainfall – runoff model of the Huangpu River in Shanghai

Shanghai is a city located in a coastal region and to understand the flood risks it is exposed to, it is of most importance to first understand the processes that control the water levels for the different flood scenarios. Historically, the Huangpu River has reached its highest levels during landfalling typhoon events, which create a combined...

2D urban flood modelling using a numerical model of Delft3D flexible mesh: A case study in downtown of Shanghai city, China

In this additional thesis a 2D urban flood model in the downtown area of Shanghai was investigated. Therefore a numerical model of Delft3D flexible mesh (DFM) was used. Since the model was investigated from scratch, a lot of data analysis and pre-processing was required to have reasonable input data. As input data a surface elevation map, a map...

Protection of Shanghai from Flooding: 'Open or closable navigational section?’

Due to Shanghai’s unique location, it is sensitive to sea level rise and land subsidence, which are directly related to urban flood protection. Flooding of Shanghai can be caused due to the following three factors: storm surge by typhoon, high tidal levels and sustained higher water levels in the Yangtze River and the Huangpu River as a result...

Flood probability analysis of the Huangpu barrier in Shanghai

The Huangpu River meanders through downtown Shanghai City and links China's third largest Lake with the Yangtze River estuary. Typhoons passing Shanghai from June to October annually are the main trigger for flooding of the Huangpu River. When storm surges due to a tropical cyclone meet the local astronomical tide, the water levels in the river...
