چکیده
Identifying risks in flood-prone areas is necessary to support risk management decisions. This research was conducted establish a vulnerability model of flood hazards the city Pontianak. The based on scoring and weighting biophysical factors. AHP method logical formulations were used model. result showed that accuracy by determine floods 80% Pontianak City. using level 84%. Kappa value 1 76.7%. explains most City has very high vulnerability, which 31,440,568.8 m2 or 29.11% total area 108,003,319.8 m2. vulnerable 29,945,485.7 27.73%, less safe 22,126,936.3 20.49%, with being 24,490,328.7 m2or 22.67% area. contributes government policies regarding urban development future, as an effort mitigate against flooding.

Optimal Flood Mitigation over Flood Propagation Approximations
Globally, flooding is the most frequent among all natural disasters, commonly resulting in damage to infrastructure, economic catastrophe, and loss of life. Since the flow of water is influenced by the shape and height of topography, an effective mechanism for preventing and directing floods is to use structures that increase height, e.g., levees and sandbags. In this paper, we introduce the Op...
متن کاملIntroducing the Flood Vulnerability Index (FVI) as a flood crisis management tool
Background and objective: Floods are among the most dangerous natural disasters that causes loss of life and property every year. The destructive effects of floods are more documentedو due to climate change and increasing economic and social development. Social and infrastructural vulnerabilities have also increased due to human settlement adjacent to river floodplains. Therefore, to prevent mo...
متن کاملLand Use Scenario Modeling for Flood Risk Mitigation
It is generally accepted that flood risk has been increasing in Europe in the last decades. Accordingly, it becomes a priority to better understand its drivers and mechanisms. Flood risk is evaluated on the basis of three factors: hazard, exposure and vulnerability. If one of these factors increases, then so does the risk. Land use change models used for ex-ante assessment of spatial trends pro...
متن کاملFlood Characteristics and Mitigation Issues
Among various natural disasters floods make the largest impact in terms of number of casualties, people affected and property lost. Flood data during the past 30 years show that flood events that cause significant impacts have increased at a steady rate. Available data suggest that this increase could be attributed to increasing population and exposure, increasing property values located in vul...
متن کاملInvolving Homeowners in Flood Mitigation
Early efforts to mitigate flood hazards emphasized structural solutions such as dams and levees. More recent strategies have stressed regulatory, nonstructural measures. In neither case, however, has homeowner involvement been given a very important role. Frustrated with the limited success of past efforts, floodplain managers recently have become more interested in encouraging homeowners to ta...
