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...

Severe floods triggered by intense precipitation are among the most destructive natural hazards in Alpine environments, frequently causing large financial and societal damage. Potential enhanced flood occurrence due to global climate change would thus increase threat to settlements, infrastructure, and human lives in the affected regions. Yet, projections of intense precipitation exhibit major ...

Natural hazards are basically the changes that occur in environmental conditions, causing a disruption of the natural life of the people and their exposure to hazardous and degradable elements and elements. Establishing cities and residential areas on landforms has created new perspectives. The development of these areas has altered the geostationary balance of many landforms, and the response ...

Varkesh-Chai River with approximately 69 kilometer and north-south trend, in one of the main and permanent rivers of Tabriz city, That 10 villages with worn out texture have established in its main bed. Field studies show that, villages’development has been without knowing the rules governing hydraulic behavior, prediction of river hydrological behavior, and no respecting the main bed of river,...

Flood susceptibility mapping using frequency ratio and weight of evidence technique: a case study of Kermanshah Province   abstract Flood is considered as one of the most destructive natural disasters worldwide, because of claiming a large number of lives and incurring extensive damage to the property, disrupting social fabric, paralyzing transportation systems, and threatening natural ecosy...

A flash flood and landslide in the Leh region of the Indus Valley in the Indian state of Jammu and Kashmir on 5–6 August 2010 resulted in hundreds of deaths and great property damage. Observations have led to the hypothesis that the storm, which formed over the Tibetan Plateau, was steered over the steep edge of the plateau by 500-hPa winds and then energized by the ingestion of lower-level moi...

This paper presents a complex approach for modelling of a tandem reservoir systems for water drainage management. The model has been built over a segment of a river with a certain parameters of water inflow, water outflow, required power production and max possible flood occurrence. Then the segments may be replicated with specific parameters to simulate whole system of the river. The model has...

Flood disasters and snow disasters are frequent disasters in China, causing considerable economic loss and serious damage to towns and farms. The problems of how these two disaster types distribute and what disaster-forming environments are important to their occurrence are the most pressing problems in disaster risk assessment and salvage material arrangement. The present study aims to establi...

Floods are one of the most common natural disasters which causing financial and life losses, yearly. Therefore, to reduce the harmful effects of flood occurrence, it is necessary to prepare vulnerability maps for flood management. The aim of the present study is flood inundation mapping of Jahrom Township, Fars Province using multi-criteria decision making techniques such as AHP and TOPSIS and ...
