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...

The evaluation of potential damage of future floods is an essential part of flood management project appraisals. Analysis results reliability is an important issue when comparing flood risk reduction project scenarios. Geographic Information System (GIS) technology plays a crucial role on flood risk analyses. On one hand, the evaluation process requires data on flood hazard and on vulnerability...

Indonesia, as a developed country, has water-related disaster problems. Flood is one of them and it occurs in mostly province, including Banten province. Lebak Regency the region Province history flood occurrences. According to Provincial BPBD (2021), among 2015-2020 period, twenty-nine events occurred Regency. The severest that period 2020. A total 2389 residents’ homes forty-five units public...

Cities increasingly face flood risk primarily due to extensive changes of the natural land cover built-up areas with impervious surfaces. In urban areas, impacts come mainly from road interruption. This paper proposes an map hydrological and mobility data, considering megacity S\~ao Paulo, Brazil, as a case study. We estimate susceptibility through Height Above Nearest Drainage algorithm; poten...

Mechanism of flood forecasting is a complex system, which involves precipitation, drainage characterizes, land use/cover types, ground water and runoff discharge. The application of flood forecasting model require the efficient management of large spatial and temporal datasets, which involves data acquisition, storage, pre-processing and manipulation, analysis and display of model results. The ...

Floods are threats seriously affecting people’s lives and property globally. Risk analysis such as flood susceptibility assessment is one of the critical approaches to mitigate impacts. However, inadequate field survey lack data might hinder mapping susceptibility. The emergence user-generated content (UGC) in era big provides new opportunities for risk management. This research proposed a mode...

the flood is one of the natural disasters that doesnt create itself but the landuse change will be caused it that makes a lot of human and financial losses every year. in this study in gonbad chi basin to assess the impact of watershed mechanical operation on flood mapping used fuzzy method and ahp method and composition of slope mapping, landuse, permeability and flow accumulation that called ...

Floods are one of the most abundant and destructive natural disasters that every year are caused heavy losses of life and property. Due to human activity in river systems and construction in rivers, flood damage has an upward trend. One of the most important actions to reduce flood damage is the provision of flood hazard zoning maps and their use in spatial planning. In this study, the risk of ...
