Flood monitoring technique using adjustable histogram equalization is proposed. The technique overcomes the limitations (overenhancement, artifacts, and unnatural look) of existing technique by adjusting the contrast of images. The proposed technique takes pre- and postimages and applies different processing steps for generating flood map without user interaction. The resultant flood maps can b...

Flood is considered as a major threat among natural disasters in the world. This case becomes more important and has a higher risk in urban areas due to the existence of important uses. Therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. Considering the development in Iran has been carried out in high risk...

My work within a research project studying flood-risk management in Hungary is described, with special attention on loss-spreading instruments, mainly insurance. I argue that computer simulation tools are useful in catastrophe policy making. Computer simulation provides a method for estimating the consequences of different potential policy strategies. In decision making processes it also forces...

Urban flooding has become an increasingly important issue in many parts of the world. In this study, an integrated flood assessment model (IFAM) is presented for the coastal urban flood simulation. A web based GIS framework has been adopted to organize the spatial datasets for the study area considered and to run the model within this framework. The integrated flood model consists of a mass bal...

abstract although many studies have been carried out about dam break, this phenomenon still is one of the most important issues in the field of hydraulic engineering due to its hazards to human societies. predicting the critical conditions including coincidence of flooding and dam break indicates more field studies requirement. in this research the mutual effects of coincidence of negative surg...

A common problem encountered by catchment managers is the estimation of design peak flow quantiles. Current practice, as discussed by Pilgrim (1987), is based either on the use of statistical approaches such as an at-site flood frequency analysis, or the use of a catchment modelling system to simulate catchment response to design rainfall. For many practical problems, the option of an at-site f...

Flood risk analysis is more complex in urban areas than that in rural areas because of their closely packed buildings, different kinds of land uses, and large number of flood control works and drainage systems. The purpose of this paper is to propose a practical framework for flood risk analysis and benefit assessment of flood control measures in urban areas. Based on the concept of disaster ri...

Floods are among the most devastating natural hazards in society. Flood forecasting is crucially important in order to provide warnings in time to protect people and properties from such disasters. This research applied the high-resolution coupled hydrologic–hydraulic model from the University of California, Irvine, named HiResFlood-UCI, to simulate the historical 2008 Iowa flood. HiResFlood-UC...

Historical flood events have shown that the level of damage does not solely depend on exposure to flood waters. Vulnerabilities due to various socio-economic factors such as population at risk, public awareness, and presence of early warning systems, etc. should also be taken into account. Federal and state agencies, watershed management coalitions, insurance companies, need reliable decision s...
