Abstract. Given the current challenges in flood risk management and vulnerability assessment of buildings exposed to flood hazards, three-dimensional numerical modelling of torrential floods and its interaction with buildings are presented. By means of a case study application, the FLOW-3D software is applied to the lower reach of the Rio Vallarsa torrent in the village of Laives (Italy). A single-family house on the flood plain is thereby considered very detailed and exposed to a 300 yr flood hydrograph. Different building representation scenarios, amongst an entire impervious building envelope and the assumption of fully permeable doors, windows and cellar shafts, are analysed. The modelling results give insight into the flooding process of the building’s interior, the impacting hydrodynamic forces on the exterior and interior walls and, further, quantify the impact of flooding a building on the flow field on the adjacent flood plain. The presented study means a step towards the development of a comprehensive physical vulnerability assessment framework. For pure water floods, it shows possibilities and limits of advanced numerical modelling techniques within flood risk management and, thereby, the planning of local structural protection measures.

Abstract. Given the current challenges in flood risk management and vulnerability assessment of buildings exposed to flood hazards, this study presents three-dimensional numerical modelling of torrential floods and its interaction with buildings. By means of a case study application, the FLOW-3D software is applied to the lower reach of the Rio Vallarsa torrent in the village of Laives (Italy). A single-family house on the flood plain is therefore considered in detail. It is exposed to a 300-year flood hydrograph. Different building representation scenarios, including an entire impervious building envelope and the assumption of fully permeable doors, light shafts and windows, are analysed. The modelling results give insight into the flooding process of the building's interior, the impacting hydrodynamic forces on the exterior and interior walls, and further, they quantify the impact of the flooding of a building on the flow field on the surrounding flood plain. The presented study contributes to the development of a comprehensive physics-based vulnerability assessment framework. For pure water floods, this study presents the possibilities and limits of advanced numerical modelling techniques within flood risk management and, thereby, the planning of local structural protection measures.

Integrated Risk Analysis

From the point of flood integrated risk analysis and risk dynamic management, analysis and discussion the reason of flood disasters occur frequently. Flood risk management is divided into six types: flood risk, flood control project risk, flood investment risk, flood plain risk, flood eco-environment risk and flood control decision risk management. Furthermore, a risk assessment model was established, and this paper puts forward four targets of flood risk management, eventually forming flood risk management flow, which provides a framework for flood integrated risk analysis and risk management.

The River Thames tidal defences have provided protection against the increasing threat of tidal flooding from the North Sea for more than 2000 years. The flood of 1953 was the catalyst for the construction of the current system of River Thames tidal defences, which includes the Thames Barrier, and has provided one of the best standards of flood defence in the UK for over 20 years. Substantial growth is planned through ‘Thames Gateway’, a regeneration initiative of the United Kingdom government. These new developments will fundamentally change the developed footprint in the Thames Estuary flood-plain, and will be in place for at least the next 100 years. This presents a challenge of planning future defence against a background of uncertainty over climate and other environmental change, while ensuring that correct decisions are made concerning the nature and location of new building in the tidal flood-plain. Through its ‘Thames Estuary 2100’ project, the Environment Agency is developing a long-term strategy for flood risk management in the estuary. Implementation of major construction works on the River Thames could commence from around 2015. Alternatively, it may be decided that minimum works are undertaken to provide security and major investment is delayed until uncertainties over climate change have abated. Whatever long-term option is chosen, this must be preceded by a period of collaboration with the Thames Gateway developments to ensure appropriate and sustainable flood defences are incorporated in new riverside construction.

Objectives of this study is to identify the real issues and challenges of flood related agencies in Malaysia. By using qualitative thematic analysis, this study found that limited authorities, lack of enforcement power, lack of cooperation among agencies, lack of man-power and assets for logistics, insufficient funding for flood risk management and communication problems are the issues faced by the flood-related agencies. The government needs to solve the issues and challenges in order to strengthen the flood-related agencies capacities.Keywords: flood risk management; flood-related agencies; issues; authorityeISSN: 2398-4287 © 2020.
