“…Risk is therefore a spatial notion, since it varies according to the space in question, as do possible flooding and potential damage. Flood risk management deals with the outcomes, which are the combinations of the probabilities of an event occurring and the impacts associated with that event (Ran and Nedovic-Budic, 2016). However, flood risk assessment deals with the estimation of the flood hazard, the potential impact on human activities, and the latter is usually identified as the product of exposure and vulnerability (Alfieri et al, 2015).…”

This paper represents an index model developed for the assessment of risk caused by river floods. The main purpose of this model is to evaluate the flood risk in the western coastal region of Mazandaran Province/Iran. The model assesses the risk at triple components, i.e. the flood occurrence probability, vulnerability and consequences, through identification and evaluation of effective criteria categorized into seven indexes (environmental, technical, economic, social, depth, population and sensitivity ones) that are involved in all stages of flooding (source, pathway and receptor). The flood risk in the developed model is defined by a dimensionless magnitude called as risk score between 0 and 100 for each zone of the area under assessment by calculating and combining of two newly defined factors: occurrence and vulnerability factor and impact factor. The model was applied in a case study, the Nowshahr flood in 2012. The results showed that: (i) the flood risk zoning was compared with observed data for aspect of the damages, and general agreement between them was obtained; (ii) for urban zones, which surrounded by two rivers, would easily be in critical condition and rescue operations face difficulties; and (iii) it is necessary to review the location of the emergency services, according the flood risk zoning.

“…It regulates the physical space and guides the course of future activities as stipulated by guiding principles (Ran and Nedovic-Budic, 2016). The main merit of integrating land use planning with flood risk management is its appeal to different stakeholders (Roth, 2012, Zyl, 2006, Galderisi and Menoni, 2015.…”

This study examines how discriminatory land use planning predisposes the low income residents to flood disaster risks in Karonga town, Malawi. Using a qualitative research design, in-depth interviews were conducted with ten government and non government institutions engaged in land use planning and disaster risk management and traditional leaders. The study showed that theoretical aims of land use planning to improve the living environment remain partial and in certain cases exacerbate risks posed by floods because the planning tool divides the urban landscape into formal and informal spaces. Such separation which coincided with incomes levels forced the marginalised and urban poor to occupy flood-prone areas While literature on flood control promotes an integrated approach to flood risk management, land use planning practice is singled out as a regulatory measure which ironically not only fails to meet the needs, but also increases vulnerability to flood risks, of the urban poor residents. The study further revealed that land use planning has failed to reduce flood disaster risks in informal spaces because it is not compatible with the needs of the urban poor.

“…The number of floods, and enhanced damage due to suitability of urban growth and light industry development [32]. Additionally, some researchers studied flood-risk assessment as a prominent component of urban planning [33][34][35]. Thus, a spatial, multi-criteria index has been proposed to characterize such areas by integrating the technology of remote sensing and GIS to measure the physical parameters of flood vulnerability.…”

Flooding has been increasing since 2004 in Japan due to localized heavy rainfall and geographical conditions. Determining areas vulnerable to flooding as one element of flood hazard maps related to disaster management for urban development is necessary. This research integrated Remote Sensing data, the Geography Information System (GIS) method and Analytical Hierarchy Process (AHP) calculation to determine the physical flood-vulnerable area in Okazaki City. We developed this research by applying data from the Geospatial Information Authority of Japan (GSI) to generate the slope map and drainage density; AMEDAS (Automated Meteorological Data Acquisition System) from the Japan Meteorological Agency (JMA) to generate the rainfall data; Soil map from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) data; and Sentinel-2 imagery to generate the land cover map. We applied the AHP calculation for weighting pairwise the parameters by comparing five iterations of the normalized matrix. We utilized the spatial analysis tool in ArcGIS to run the pairwise comparison to adjudicate the distribution of flooding according to the AHP procedure. The percentage of relative weight was slope (43%), drainage density (20%), rainfall intensity (17%), then both infiltration rate and land cover (10%). The consistency value was reasonable: consistency index (CI-0.007) and consistency ratio (CR-0.6%). We generated high accuracy for flood vulnerability prediction; 0.88 for Probability of Detection (POD), 0.28 for Probability of False Detection (POFD), 0.44 for Critical Success Index (CSI), 1.9 for Bias, and 95 of Area under Curve (AUC). The flood vulnerability was matched to the flood inundation survey of Okazaki City in August 2008 and indicated an excellent Relative Operating Characteristic (ROC).
