【 摘 要 】

The vulnerability, flood hazards, and exposure are three indicators to calculating and assessing flood risk in the Mekong Delta river. Flood risk assessments allows managers to understand the probability and implications of potential damage caused by floods. The vulnerability index is based on three criteria, including sensitivity and adaptive capacity related to the economic, social, and environmental aspects and benefits that floods bring to the Mekong Delta river. The flood events occurred in the years that the flood peak at Tan Chau was over 4 m, causing the most severe damage in this area. This paper will use the vulnerability index method which is the sum of the components including the sensitivity, resilience and benefits of floods to calculate and assess the flood vulnerability of 155 communes in 11 districts of An Giang province. The results showed that there are four communes were affected by average vulnerability and 151 communes with high vulnerability.
