Probabilistic Flood Risk Assessment Under Climate Change Scenarios in the Humber River Watershed
Flood frequency is expected to increase due to climate change. This research uses the CAPRA method to perform flood risk assessment in the Humber River watershed. The economic and social damages are quantified under current and future climate conditions. First current and future stochastic …

A participatory GIS approach to flood risk assessment of informal settlements the case of Cape Town
… most of these settlements are prone to flooding after prolonged rainfall. Current flood risk management techniques implemented by the authorities of the Cape Town City Council (CTCC) are ideal for formally planned settlements but are not designed to support informal settlements...This …

Flood risk assessment using multi-sensor remote sensing, geographic information system, 2D hydraulic and machine learning based models
Flooding events threaten the population, economy and environment worldwide. In recent years, several spatial methods have been developed to map flood susceptibility, hazard and risk for predicting and modelling flooding events. However, this research proposes multiple state-of-the-art approaches to …

MODELLING, ASSESSMENT, AND REDUCTION OF FLOOD RISK IN NEPAL
There is a lack of modelling methods for flood risk assessment models that are applied for data-scarce flood-prone areas and where flood risk is quantified as economic damage. In addition, there is a lack of flood risk assessment models towards flood risk reduction in data-scarce flood-prone areas …

Risk-Based Decision Making Model for the Selection of Flood Mitigation Alternatives
… disasters such as wildfires, hurricanes and flooding, resulting in big economic, environmental, and social impacts. In the case of flood events, impacts such as community anxiety, loss of life, water pollution, and contamination of agricultural land have been found to be equally, if not more …

A novel approach for large-scale flood risk assessments
In the past, floods were basically managed by flood control mechanisms. The focus was set on the reduction of flood hazard. The potential consequences were of minor interest. Nowadays river flooding is increasingly seen from the risk perspective, including possible consequences. Moreover, the …

Analysing urban flood risk in low-cost settlements of George, Western Cape, South Africa : investigating physical and social dimensions
… both the physical and social dimensions of urban flood risk. The following analytical questions are therefore considered: i) What constitutes urban flooding? ii) What processes influence the urban flood hazardscape? iii) What makes people vulnerable to urban flooding? iv) How does one assess urban …

Understanding trans-basin floods in Germany : data, information and knowledge
Large Central European flood events of the past have demonstrated that flooding can affect several river basins at the same time leading to catastrophic economic and humanitarian losses that can stretch emergency resources beyond planned levels of service. For Germany, the spatial coherence of …
