Flood is one of the most dangerous natural disaster in Vietnam. Assessing flood hazard is a long term ambition of the society, especially in low-land cities where almost its communities expose to flood caused by heavy rainfall over its upstream river basin.

The paper reviews three major schools of thought concerning (i) vulnerability and resilience are two sides of the same coin, (ii) resilience is a part of vulnerability, and (iii) they are two separated concepts with some overlaps. Limitations of the schools of thought were assessed based on four main criteria: (i) vulnerability and resilience must reflect all social, economic and environmental aspects, (ii) they exist regardless of hazards, (iii) they are processes than outcomes, and (iv) they entail multiple objectives.

Geographic Information Systems (GIS) has emerged as one of the most important and widely used softwares for the social scientists in last two decades. Economists, sociologists, political scientists, public administrators, and geographers alike use GIS for capturing, storing, analyzing, and presenting spatially referenced socio-economic data. Election campaigns have been using GIS in a rapidly increasing manner. It has also been substantially used by urban and regional planners, natural resources scientists, and civil engineers.
