The high-risk areas of the river basin were identified using a flood risk map. AHP in combination with the GIS framework can be used as an alternative method for flood inundation or for developing the map of flood-prone zone of data-scarce river basins....
the model are to synthesis the spatial-referenced data and create the risk zone. The diffusion of Geographical Information Systems (GIS) technology opens up a range of new possibilities for hazard mitigation and disaster management. Microzonation is greatly facilitated by the kind of automation that...

This study examined the flood prone areas within Metro Manila to find out their degrees of disaster risk. More specifically, the study considered the population densities of Metro Manila barangays, the smallest political units of the country, the gender and age population, the structural materials ...
A GIS database of indicators for the evaluation of hazard and vulnerability was created. Each indicator was analyzed, standardized, and weighted; after which, the weights of the indicators were combined to obtain the final flood risk index map. Using the flood risk index, the study area was ...
Geographical Information System (GIS) is integrated with Multicriteria Decision Analysis (MCDA) to evaluate the potential flood risk areas. Some of the causative factors for flooding in watershed are taken into account as annual rainfall, basin slope, drainage network and the type of soil. The ...
Step 2: Prepare the data for analysisNow that you’ve collected your data, you need to prepare it to find risk areas. In this case you will use proximity to evacuation routes, proximity to flood zones, and vehicle ownership to determine risk. All of the risk zones will be within the ...
This can be better accomplished using a Rapid Flood Risk Assessment (RFRA) approach which requires minimal data and modelling work. The approach is GIS‐based, using only data on land use and elevation as input, and does not require hydrodynamic computations. A small section of the River Elbe...
this paper assessed flood risk in the Dongting Lake region, Hunan Province, Central China, an area where flood hazards frequently occur. The model was designed using spatial multi-criteria analysis (SMCA) techniques in a Geographic Information System (GIS). A GIS database of indicators for the...
Application of GIS and factor of safety in determining landslide risk area in Tapi watershed, Changwat Nakhon Si Thammarat It is increasingly recognized that a comprehensive understanding of the existing flood system is necessary to effectively manage coastal flood risk. This involves consideration of ...
