This paper reports the research conducted in the framework of a project, which focused on the flooding issues in the Haor region in the north-east of Bangladesh. Section 2 introduces to the study area, Section 3 presents the set up of the simulation models, Section 4 introduces to flood index used subsequently in characterising flooding in the study area and Section 5 presents the results. The probable impact of climate change is discussed in Section 6.. 2 Study area
