In general, these methods can be classified into two groups: (i) direct-qualitative (survey methods, integrated map ...) and (ii) indirectly-quantitative (method index). The set of indicator plays a very important role in the successful application to any method and brings reliable results. Each basin or area with different natural geography, economics and society and so on, requires a different set of indicator. However, assessing any river basin in Vietnam needs the basic indicator.

文摘Along with the concept, the method of assessing the vulnerability is becoming more and more diversified in many directions and fields. In general, these methods can be classified into two groups: (i) direct-qualitative (survey methods, integrated map ...) and (ii) indirectly-quantitative (method index). The set of indicator plays a very important role in the successful application to any method and brings reliable results.

This study will establish the basic indicator for the construction of flood vulnerability index in Vietnam.
