The climatic and geographic features of central Vietnam frequently contribute to annual floods, and several disastrous floods have been recorded in the last few decades. The most recent and disastrous flood, in 1999, is still memorable within the affected area, due to the magnitude of catastrophe inflicted by floodwaters. However, the flooding effects in rural areas are not often reported in detail. This study aims to clarify flood-adaptation measures and the vulnerability of housing conditions in the flood-prone area, based on a field survey of a lagoon village. The surveyed houses can be classified into four different types that have similar spatial layouts. Most of the surveyed houses show characteristics of adapting well to annual floods; for example, floor levels are conventionally raised to adjust to the height of annual floodwaters in each location. Nonetheless, housing conditions are still vulnerable to future disastrous floods, as efficient flood-prevention features—such as the provision of two-story durable housing—often prove too expensive for most villagers. Thus, villagers need to develop other measures to prepare themselves better for disastrous flooding.
