This paper presents an approach to enhance the role of local stakeholders in dealing with urban floods. The concept is based on the DIANE-CM project (Decentralised Integrated Analysis and Enhancement of Awareness through Collaborative Modelling and Management of Flood Risk) of the 2nd ERANET CRUE funding initiative. The main objective of the project was to develop and test an advanced methodolo...

Volunteered Geographic Information (VGI) has been used to complement or substitute authoritative data in flood management domain. The main issue regarding the use of volunteered information is to estimate its quality, mainly because it may suffer from heterogeneous quality. Therefore, several methods have been developed in the past few years in order to assess VGI quality. However, existing wor...

the response of karoun basin in lumped and semi-distributed simulation were compared. also, the flood intensity of the sub-basins and the effects of physical parameters on flood hydrograph have been investigated. results demonstrated that there was no significant difference between the characteristics of flood hydrograph in lumped and semi-distributed simulation. also, results showed that the f...

Introduction Coastal floods account for a large proportion of the damage to life and property due to natural disasters world-wide. Out of the 15 greatest natural disasters in the world in terms of monetary losses between 2004 and 2008, 14 were coastal (Kron 2008). However, despite the enormity of a particular flood event, people often return to a flood-prone area after a disaster (Cigler 2007; ...

Flooding is one of the most damaging of natural disasters. Structural approaches to flood management consist of reservoirs and dams equipped with floodgates, along with protocols for their operation. However, in spite of the infrastructure being in place, floods can occur because of flaws in the floodgate operation protocols or human error in its implementation. Hybrid automata are a formalism ...

Flood defence maintenance strategies require understanding of the time-dependent behaviour of flood defences. Quantitative risk and reliability methods provide a rational decision-making basis for flood defence management. Failure mechanisms influencing the flood defence reliability are expressed by a limit state equation and organised in a fault tree. One or more random variables in the limit ...

In October 2000, the flow of the River Murray entering South Australia was increased from 32 000 to 42 050 ML day 1 by release of water from an offstream reservoir, and a downstream weir was raised by 500 mm to impound the flood and enhance local floodplain inundation. The flood was maintained for about two weeks, although the duration of inundation was longer at low elevations on the floodplai...

An exhaustive knowledge of flood risk in different spatial locations is essential for developing an effective flood mitigation strategy for a watershed. In the present study, a risk-vulnerability analysis to flood is performed. Four components of vulnerability to flood: 1) physical, 2) economic, 3) infrastructure and 4) social; are evaluated individually using a Geographic Information System (G...
