Mapping flood inundation can be done by different methods, of which GIS analysis and flood modeling can be considered as the most popular ones. The modeling approach often requires more data but produce more detail results comparing to the GIS. Based on the assessment of current applied methods for building flood inundation map in the Mekong delta provinces in general and Long An in particular as well as based on some recent results of using GIS, 1 D ISIS model and 1-2D Mike Flood model applied in Long An province, the author show advantages as well as disadvantages of each methods and especially the results’ confidence. As the result, the author presents some challenges in mapping flood inundation maps under climate change and sea level rise. Integrating hydraulic construction (e.g. dyke, sluice, storage areas) and adaptation measures in the current and future in the analysis are typical challenges.
