Among the various factors that contribute to flood risk, heavy storms, inadequate storm drainage systems, and the concentration of population and assets have usually been considered to be fundamental factors affecting flood damage. Climate change is also a real threat, bringing heavier and more frequent storms. This study presents a methodology for comparatively evaluating the impact of the flo...

The worsening condition of floods in Malaysia, in terms of frequency and impact, calls for improvement in all aspects of flood management. In addition to technology enhancement of, and developing expertise, it is hoped that improvement on the governance of flood management could alleviate the problems relating to floods. Governance of flood management aims to address the issues related to flood...

flood risk zonation is necessary to control and predict the amplitude of flood damage.the purpose of this research is to evaluate the rate of flood risk vulnerability and the flood damage assessment in tabriz. specific variables of this study are land use , population density , river beds , slope classes residential density , cn coefficient , runoff coefficient , open spaces and old buildings.m...

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...

Floods are one of the most common hazards in the world, affect ing people’s lives and livelihoods. Flood hazard mapping and flood shelters suitability analysis are v ital elements in appropriate land use planning for flood-prone areas. This paper describes application of Remote Sensing (RS) and Geographical Information Systems (GIS) in identifying flood hazard zones and flood shelters and are t...

Inland riverine flooding from tropical cyclones (TCs) is responsible for significant economic losses in the United States. Yet, most hurricane loss assessment efforts are focused on coastal areas. Hurricane Irene, which struck the U.S. east coast in 2011, provides a recent and poignant example: while intense media coverage and preparation and evacuation activities focused on the projected coast...

Flood hedging reservoir operation is when a pre-storm release creates a small flood downstream to reduce the likelihood of a more damaging but uncertain larger flood in the future. Such pre-storm releases before a flood can increase reservoir storage capacity available to capture more severe flood flows, but also can immediately increase downstream flood damage and reduce stored water supply. T...

Fitting flood prediction curves by eye to the data of return period plots is an intuitive approach to estimating «-year flood discharge magnitudes from single-site data. However, the subjective nature of this "procedure" means that it is unlikely to be adopted as a recognized flood estimation technique. An experiment with a group of volunteers demonstrates that some individuals are capable of s...

Flood mitigation measures implemented by private households have become an important component of contemporary integrated flood risk management in Germany and many other countries. Despite the growing responsibility of private households to contribute to flood damage reduction by means of private flood mitigation measures, knowledge on the long-term development of such measures, which indicates...
